HEART-LUNG PRESUMPTION

Without a statutory exception, in heart attack cases, the claimant must show an injury by accident and an identifiable incident at a reasonably definite time. The claimant must prove that particular work activity caused or contributed to cause the heart attack. If the heart attack was a natural coincidence of preexisting heart disease or physical and emotional stress over a period of weeks, the heart attack is not compensable. D.W. Mallory & Co. v. Phillips, 219  Va. 845, 252 S.E.2d 319 (1979); Woody v. Mark Winkler Mgt., Inc., 1 Va. App. 147, 336 S.E.2d 518 (1985).

Statutory  Provision. §65.2-402. Presumption as to death or disability from respiratory disease, hypertension or heart disease.

A. Respiratory diseases that cause (i) the death of volunteer or salaried firefighters or Department of Emergency Services hazardous materials officers, or (ii) any health condition or impairment of such firefighters or Department of Emergency Services hazardous materials officers resulting in total or partial disability shall be presumed to be occupational diseases, suffered in the line of duty, that are covered by this title unless such presumption is overcome by a preponderance of competent evidence to the contrary. For purposes of this section, the term "firefighter" shall include persons who are employed by or contract with private employers primarily to perform firefighting services.

B. Hypertension or heart disease causing the death of, or any health condition or impairment resulting in total or partial disability of (i) salaried or volunteer firefighters, (ii) members of the State Police Officers' Retirement System, (iii) members of county, city or town police departments, (iv) sheriffs and deputy sheriffs, (v) Department of Emergency Services hazardous materials officers, (vi) city sergeants or deputy city sergeants of the City of Richmond, and (vii) game wardens who are full-time sworn members of the enforcement division of the Department of Game and Inland Fisheries shall be presumed to be occupational diseases, suffered in the line of duty, that are covered by this title unless such presumption is overcome by a preponderance of competent evidence to the contrary.

C. Leukemia or pancreatic, prostate, rectal, or throat cancer that is caused by a documented contact with a toxic substance that a volunteer or salaried firefighter or Department of Emergency Services hazardous materials officer having completed twelve years of continuous service has encountered in the line of duty and that causes (i) the death of such person or (ii) any health condition or impairment of such person resulting in total or partial disability shall be presumed to be an occupational disease, suffered in the line of duty, that is covered by this title, unless such presumption is overcome by a preponderance of competent evidence to the contrary. For the purposes of this section, a "toxic substance" is one which is a known or suspected carcinogen, as defined by the International Agency for Research on Cancer, and which causes, or is suspected to cause, leukemia or pancreatic, prostate, rectal or throat cancer.

D. The presumptions described in subsections A, B, and C of this section shall only apply if persons entitled to invoke them have, if requested by the private employer, appointing authority or governing body employing them, undergone preemployment physical examinations that (i) were conducted prior to the making of any claims under this title that rely on such presumptions, (ii) were performed by physicians whose qualifications are as prescribed by the private employer, appointing authority or governing body employing such persons, (iii) included such appropriate laboratory and other diagnostic studies as the private employer, appointing authorities or governing bodies may have prescribed, and (iv) found such persons free of respiratory diseases, hypertension, cancer or heart disease at the time of such examinations.

E. Persons making claims under this title who rely on such presumptions shall, upon the request of private employers, appointing authorities or governing bodies employing such persons, submit to physical examinations (i) conducted by physicians selected by such employers, authorities, bodies or their representatives and (ii) consisting of such tests and studies as may reasonably be required by such physicians. However, a qualified physician, selected and compensated by the claimant, may, at the election of such claimant, be present at such examination.

F. Whenever a claim for death benefits is made under this title and the presumptions of this section are invoked, any person entitled to make such claim shall, upon the request of the appropriate private employer, appointing authority or governing body that had employed the deceased, submit the body of the deceased to a postmortem examination as may be directed by the Commission. A qualified physician, selected and compensated by the person entitled to make the claim, may, at the election of such claimant, be present at such postmortem examination.

G. Volunteer lifesaving and rescue squad members, volunteer law-enforcement chaplains, auxiliary and reserve deputy sheriffs, and auxiliary and reserve police are not included within the coverage of this section.


Nature of the Heart-Lung Presumption--Burden of Proof is Shifted to Employer.

    The commission misapplied the legal precedent implementing the statutory presumption of Code Sec. 65.2-402 in finding claimant's respiratory disease was caused by his work as a firefighter and was thus a compensable occupational disease. Claimant served as a volunteer firefighter from age 15 until he became a full-time paid firefighter in 1972 and continuing until his death.  He smoked an average of three-quarters of a
pack of cigarettes a day from age 18 until approximately 1994 when he was diagnosed with squamous cell carcinoma (lung cancer).  Claimant died on September 4, 1996.  All the physician experts agreed claimant's cigarette smoking was a cause of his lung cancer.  The employer's experts, for various reasons, opined claimant's work as a firefighter did not cause his lung cancer.  The claimants' experts, other than Dr. Susan M. Daum, only opined that they could not exclude claimant's work-related exposure to toxins as a cause of the disease.  Dr. Daum explicitly opined claimant's occupational exposure was a cause of his lung cancer.  No evidence in the record established the quantity of claimant's exposure to possible disease-causing substances or fixed the toxicity of any exposure. In summary, the evidence was in conflict as to whether claimant's  possible exposure to hazardous substances as a firefighter was a cause of his lung cancer.
    Code Sec. 65.2-402  applies to designated public safety employees, including firefighters like claimant.  The statute establishes that respiratory diseases "shall be presumed to be occupational diseases suffered in the line of duty . . . unless such presumption is overcome by a preponderance of competent evidence to the contrary."  Code Sec. 65.2-402(A). [T]he purpose of the statutory presumption is to establish by law, in the absence of evidence, a causal connection between certain occupations and death or disability resulting from specified diseases. . . .To overcome the statutory presumption the employer must show, by a preponderance of the evidence, both that 1) the claimant's disease was not caused by his employment, and 2) there was a non-work-related cause of the disease.  Thus, if the employer does not prove by a preponderance of the evidence both parts of this two-part test, the employer has failed to overcome the statutory presumption. Bass v. City of Richmond, 258 Va. 103, 112-14, 515 S.E.2d 557, 562-63(1999) (citations omitted).
    In the case at bar, the commission properly found, and the claimants do not contest, that the employer met its burden as to the second prong of the Bass test:  there was a non-work-related cause of Woody's lung cancer which was his cigarette smoking
    As to the first prong of the Bass test, the commission held that the presumption precludes rebuttal by the employer where there is any evidence that a statutorily qualified employee had any level of exposure "to properties in the course and scope of their employment that cause respiratory disease." The commission's decision is in error as the commission failed to follow the plain language of Code Sec. 65.2-402(A), which establishes a rebuttable presumption, not a conclusive presumption.  Under the commission's rationale, any person who worked as a statutorily designated employee and who contracted a disease covered by the statute would conclusively be entitled to an award upon production of any evidence of any exposure to any potentially causative disease factor in the work environment.  It would be irrelevant whether that exposure had, in fact, any causative effect on the claimant.  In effect, the commission held that exposure, not proof of causation, was all a claimant need show to render the rebuttable presumption a nullity by conversion to a conclusive presumption.
    Had the General Assembly wished to write a conclusive presumption into Code Sec. 65.2-402, it could have done so.  It did not.  Instead, the legislature has directed the commission to determine cases according to the weighing of the evidence, and the commission is without authority to change that statutory provision.  Bass, 258 Va. at 114, 515 S.E.2d at 562-63. Henrico Division of Fire v. Estate of William Woody, Record No. 1254-02-4 (December 3, 2002). WP Version.

In Claude A. Bass, Jr. v. City of Richmond Police Department, Record No. 980612; John B. Patton, Jr. v. Loudoun County Board of Supervisors, Record No. 980861; City of Hopewell, et al. v. Michael W. Tirpak, Record No. 982126 (June 11, 1999), WP Version, Bass v. City of Richmond Police Dep't, 258 Va. 103, 515 S.E.2d 557 (1999), the Supreme Court clarified what is needed to overcome the statutory presumption. Under the statutory language, the employer may overcome the presumption by producing "a preponderance of competent evidence to the contrary." Code Sec. 65.2-402(B). To overcome the presumption the employer must show, by a preponderance of the evidence, both that 1) the claimant's disease was not caused by his employment, and 2) there was a non-work-related cause of the disease. See Fairfax County Fire & Rescue Servs. v. Newman, 222 Va. 535, 539, 281 S.E.2d 897, 899-900 (1981); Page v. City of Richmond, 218 Va. 844, 847-48, 241 S.E.2d 775, 777 (1978). Thus, if the employer does not prove by a preponderance of the evidence both parts of this two-part test, the employer has failed to overcome the statutory presumption. Id. In Code Sec. 65.2-402(B), the legislature included "[h]ypertension or heart disease" among those diseases that "shall be presumed to be occupational diseases . . . unless such presumption is overcome by a preponderance of competent evidence to the contrary." In Page v. City of Richmond, 218 Va. 844, 847, 241 S.E.2d 775, 777 (1978), the Supreme Court explained that the purpose of the statutory presumption is to establish by law, in the absence of evidence, a causal connection between certain occupations and death or disability resulting from specified diseases. The Court held that a claimant firefighter was entitled to compensation benefits because his employer had failed to overcome the statutory presumption by showing both that 1) the claimant's disease was not caused by his employment, and 2) there was a non-work-related cause of the disease. Id. at 847- 48, 241 S.E.2d at 777. The Supreme Court again applied this two-part test in Fairfax County Fire & Rescue Servs. v. Newman, 222 Va. 535, 281 S.E.2d 897 (1981). There, a firefighter who developed sarcoidosis, a disease affecting the lungs, relied on the statutory presumption of occupational disease provided by former Code Sec. 65.1-47.1. The employer produced medical testimony that the firefighter's employment did not cause his disease, but the employer failed to present any medical evidence of a non-work-related cause of the disabling disease. Since the employer failed to prove one of the two elements required to overcome the statutory presumption, the Court upheld the Commission's award of benefits. Id. at 539, 281 S.E.2d at 900; see also Berry v. County of Henrico, 219 Va. 259, 265, 247 S.E.2d 389, 392 (1978). In Doss v. Fairfax County Fire & Rescue Dep't., 229 Va. 440, 331 S.E.2d 795 (1985), the Supreme Court applied the two-part test to a firefighter's claim for benefits for a respiratory disease. The claimant relied on the statutory presumption and presented no evidence to counter the employer's medical evidence that 1) the claimant's job did not cause his respiratory disability, and 2) the claimant's condition was "more than likely a hereditary phenomenon." Id. at 441-42, 331 S.E.2d at 795-96. The Court held that the Commission did not err in ruling that the employer presented sufficient evidence to overcome the statutory presumption, and that the evidence concerning a "hereditary" cause was sufficient to meet the Page requirement that the employer produce evidence of a non-work-related cause of the disease. Id. at 442-43, 331 S.E.2d at 796-97. In Augusta County Sheriff's Dep't v. Overbey, 254 Va. 522, 492 S.E.2d 631 (1997), the employer acknowledged the applicability of the two-part test by conceding that, to overcome the statutory presumption of Code Sec. 65.2-402(B), the employer was required "to establish a non-work-related cause for [the claimant's] heart condition and that job stress was not the cause." 254 Va. at 526, 492 S.E.2d at 633. The claimant contended, however, that the presumption also imposed on the employer the burden of "producing a preponderance of evidence excluding the possibility that his heart disease was work related." Id. In rejecting the claimant's contention, the Supreme Court quoted from Doss, stating that, to overcome the statutory presumption, the employer merely "must adduce competent medical evidence of a non-work-related cause of the disabling disease." Overbey, 254 Va. at 527, 492 S.E.2d at 634 (quoting Doss, 229 Va. at 442, 331 S.E.2d at 796). This quotation was made in the context of the Court's holding that, to overcome the statutory presumption of Code Sec. 65.2-402(B), an employer is not required to exclude the possibility that job stress may have been a contributing factor in the development of a claimant's heart disease. Id. at 527, 492 S.E.2d at 634.

The commission improperly concluded that his employer presented sufficient evidence to overcome the occupational disease presumption established in Code Sec. 65.2-402(B) of the Workers' Compensation Act. 
    Dr. Stuart F. Seides, a cardiologist who, at the request of claimant's employer, examined claimant and reviewed some of his medical records, noted that claimant was found shortly after the heart attack to have "multi-vessel coronary atherosclerosis with critical obstruction of the 'culprit' right coronary artery." Dr. Seides further noted that claimant's "symptom onset did occur in the setting of his patrol duties," but added that it is highly likely that the myocardial infarction would have occurred in or around the same time frame regardless of his activities. Although "stress" is often considered to be an important trigger for myocardial infarction, most infarcts occur in the absence of an identifiable environmental event and in those cases where there is an apparent association, it may be simple coincidence. What is most important is the presence of the underlying substraight of atherosclerosis which is a multifactorial process developing over a period of many years in the setting of the risk factors outlined in this case. The relationship of occupation to the development of atherosclerosis is virtually nil.
   
In this case, the commission relied wholly upon Dr. Seides' medical opinion that the "relationship of occupation to the development of atherosclerosis is virtually nil" to conclude that claimant's heart disease was not caused by his employment. That opinion, however, merely rebuts generally the underlying premise of Code Sec. 65.2-402(B), which establishes the presumptive causal link between occupational stress and heart disease. Accordingly, Dr. Seides' opinion that the "relationship of occupation to the development of atherosclerosis is virtually nil" is not probative evidence for purposes of overcoming the presumption of Code Sec. 65.2-402, and the commission erred in relying on it. Disregarding that evidence, it cannot be concluded that the employer has rebutted the presumption. John B. Patton, Jr. v. Loudoun Co. Bd. of Supervisors, Record No. 1055-00-4 (August 28, 2001). WP Version.

To rebut the statutory presumption, "the employer must show, by a preponderance of the evidence, both that 1) the claimant's disease was not caused by his employment, and 2) there was a non-work-related cause of the disease." Bass v. City of Richmond Police Dep't, 258 Va. 103, 515 S.E.2d 557 (1999) (citing Fairfax County Fire & Rescue Servs. v. Newman, 222 Va. 535, 539, 281 S.E.2d 897, 899-900 (1981); Page v. City of Richmond, 218 Va. 844, 847-48, 241 S.E.2d 775, 777 (1978)). Evidence that job-related stress is one of several factors contributing to a claimant's heart disease, if found credible by the commission, is sufficient to prevent an employer from proving the first prong required to rebut the presumption. Id. (implicitly holding such evidence sufficient by remanding case with those facts to commission for application of the proper legal standard); Augusta County Sheriff's Dep't. v. Overbey, 254 Va. 522, 527, 492 S.E.2d 631, 634 (1997) (noting that a claimant is entitled to benefits under Code Sec. 65.2-402(B) when the evidence shows that at least one cause of the claimant's heart disease was "related to the employment"). Claimant's treating physician opined that job stress contributed to claimant's coronary artery disease. Accordingly, the commission did not err in holding that employer failed to rebut the presumption of Code Sec. 65.2-402 that claimant's heart disease was an occupational disease. Tazewell County Sheriff's Office v. Owens, Record No. 0005-99-3 (June 29,1999). WP Version.

After working as a firefighter for about eight years, claimant was diagnosed with asymptomatic complete heart block. The doctors who examined him believed the cause of his condition was unknown or unclear. The Supreme Court recently held that "[t]o overcome the presumption [contained in Code Sec. 65.2-402(B)], the employer must show, by a preponderance of the evidence, both that (1) the [employee's] disease was not caused by his [or her] employment, and (2) there was a non-work-related cause of the disease." Bass v. City of Richmond Police Dep't, 258 Va. 103, 515 S.E.2d 557 (1999). WP Version. Thus, it follows that "if the employer does not prove by a preponderance of the evidence both parts of this two-part test, the employer has failed to overcome the statutory presumption." Id. In this case there was no evidence of a non-work-related cause. The commission did not err in ruling that the record failed to establish by a preponderance of credible evidence a non-work-related cause of claimant's disease. City of Richmond Fire Department v. George J. Dean, Record No. 1731-98-2 (July 27, 1999) WP Version.

The commission did not err in finding that cardiac arrhythmia constituted a compensable occupational disease.  Determining whether a condition constitutes an occupational disease is a mixed question of law and fact and is subject to judicial review.  See A New Leaf, Inc. v. Webb, 257 Va. 190, 196, 511 S.E.2d 102, 104 (1999) (citations omitted). WP Version. In its decision, the commission was required to resolve conflicting medical opinions. The medical opinions differed on whether claimant's cardiac arrhythmia constituted an occupational disease.  The record supports its finding that claimant's cardiac arrhythmia was a compensable disease. Code Sec. 65.2-402(B) provides: Hypertension or heart disease causing . . . any health condition or impairment resulting in total or partial disability of . . . deputy sheriffs . . . shall be presumed to be occupational diseases, suffered in the line of duty, that are covered by this title unless such presumption is overcome by a preponderance of competent evidence to the contrary. In Bass v. City of Richmond Police Dep't, 258 Va. 103, 515 S.E.2d 557 ( 1999). WP Version, the Supreme Court held: "[t]o overcome the presumption, the employer must show, by a preponderance of the evidence, both that (1) the disease was not caused by his employment, and (2) there was a non-work-related cause of the disease."  Id. at 114, 515 S.E.2d at 562-63 (citation omitted). In this case, the commission considered both parts of that two-part test.  It noted that prior to Augusta County Sheriff's Dep't. v. Overbey, 254 Va. 522, 492 S.E.2d 631 (1997), "the employer had to pass a two-pronged test to rebut the presumption.  First, the evidence had to establish a probable non-work-related cause of the disease. . . . Secondly, the evidence had to exclude work-related factors as a possible contributing cause of the disease." The commission found that employer satisfied one prong of the test because it presented evidence that there were non-work-related causes of the disease, primarily claimant's consumption of nicotine, alcohol, and caffeine.  However, to satisfy the second prong of the test, employer had to exclude claimant's work as a factor in his condition.  This it failed to do.  To the contrary, the commission found "the evidence is sufficient to prove [claimant's] work was a proximate cause of his cardiac arrhythmia.” The record supports the commission's finding. Claimant's use of nicotine, caffeine and alcohol contributed to the origination and continuation of his cardiac arrhythmia. When medical opinions conflict, the general rule is that when an attending physician is positive in his diagnosis of a disease, great weight will be given by the courts to this opinion. See McPeek v. P.W. & W. Coal Co., 210 Va. 185, 188, 169 S.E.2d 443, 445 (1969). Based on the entire record, the commission properly concluded that claimant's cardiac arrhythmia was caused, at least in part, by the significant stress he experienced in the line of duty.  Employer failed to rebut the statutory presumption by excluding work stress as a contributing factor. Henrico County Sheriff's Office v. Paul T. McQuayRecord No. 2241-98-2 (August 17, 1999). WP Version.

The commission,  in its role as fact finder, found that employer's evidence failed to establish by a preponderance of the evidence a non-work-related cause of claimant's heart disease and that employer consequently failed to rebut the statutory presumption. We cannot conclude as a matter of law that the commission erred in its ruling. To rebut the presumption of Code Sec. 65.2-402(B), employer was required to produce affirmative evidence of a non-work-related cause of claimant's orthostatic hypotension. See Bass v. City of Richmond Police Dep't, 258 Va. 103, 115, 515 S.E.2d 557, 563 ( 1999). WP Version. Because employer's evidence did not prove by a preponderance of the evidence that claimant's family history or history of smoking caused him to develop orthostatic hypotension, the commission did not err by finding that employer failed to rebut the statutory presumption that claimant's condition is a compensable occupational disease. See City of Norfolk v. Lillard, 15 Va. App. 424, 426, 424 S.E.2d 243, 245 (1992) ("In the absence of competent evidence to the contrary, the statutory presumption controls and the claimant prevails.").The Workers' Compensation Act provides for coverage of occupational diseases arising out of and in the course of employment. See Code Sec. 65.2-101; A New Leaf, Inc. v. Webb, 26 Va. App. 460, 465, 495 S.E.2d 510, 513 (1998), aff'd, 257 Va. 190, 511 S.E.2d 102 (1999). WP Version. Under Code Sec. 65.2-402(B), a heart disease incurred by a deputy sheriff is "presumed to be [an] occupational disease[], suffered in the line of duty, that [is] covered by [the Act] unless such presumption is overcome by a preponderance of competent evidence to the contrary." The Supreme Court of Virginia recently re-affirmed the principle that an employer may rebut the presumption of Code Sec. 65.2-402(B) by proving by a preponderance of the evidence that: 1) the claimant's disease was not caused by his or her employment, and 2) there was a non-work-related cause of the disease. See Bass v. City of Richmond Police Dep't., 258 Va. 103, 115, 515 S.E.2d 557, 563 (1999). WP Version. When the commission determines that an employer has failed to overcome the statutory presumption, the claimant is entitled to an award of benefits. See Code Secs. 65.2-400 to 407. Even had the medical records established a family history of heart disease, employer failed to prove by a preponderance of the evidence that this risk factor actually caused claimant's orthostatic hypotension. "[T]he showing of 'risk factors' alone does not rebut the statutory presumption and does not establish competent medical evidence of a non-work-related cause of the disabling disease." City of Norfolk v. Lillard, 15 Va. App. 424, 429, 424 S.E.2d 243, 246 (1992).references do not constitute evidence that claimant's orthostatic hypotension was, in fact, of genetic or inherited origin, in whole or in part. See id. Cf. Augusta County Sheriff's Dep't v. Overbey, 254 Va. 522, 525, 527, 492 S.E.2d 631, 633, 634 (1997) (finding that employer established a non-work-related cause of claimant's heart disease based in part on the uncontradicted deposition testimony of the attending physician that several non-work-related risk factors "caused" the claimant's heart disease). Claimant also had a history of smoking as a risk factor. No evidence was admitted, however, concerning the actual effect of claimant's smoking on his cardiovascular health. No physician opined that smoking caused claimant's orthostatic hypotension. Although employer may have established that claimant's history of smoking was a risk factor for heart disease, employer failed to present sufficient medical evidence that claimant's smoking habits actually caused orthostatic hypotension. See Lillard, 15 Va. App. at 429, 424 S.E.2d at 246. City of Portsmouth Sheriff's Dept. v. Stephen Clark, Record No. 2667-98-1 (September 7, 1999). WP Version. 


The Supreme Court reaffirmed the standard for an employer seeking to rebut a law enforcement officer's use of the causation presumption. "[I]n order to overcome the statutory presumption, the employer merely 'must adduce competent medical evidence of a non-work-related cause of the disabling disease.'" Augusta County Sheriff's Dep't. v. Overbey, 254 Va. 522, 492 S.E.2d 631 (1997), (citing Doss v. Fairfax County Fire & Rescue Dep't, 229 Va. 440, 442, 331 S.E.2d 795, 796 (1985)). The Court announced that nothing in the statute or the several decisions of this Court dealing with rebuttal of this presumption suggests that the employer has the burden of excluding the "possibility" that job stress may have been a contributing factor to heart disease. Augusta County Sheriff's Dep't v. Overbey, 254 Va. 522, 492 S.E.2d 631 (1997) The purpose of the presumption provided by Code Sec. 65.2-401(B) is to establish a causal connection between, inter alia, disability from heart disease and the occupation of a state trooper. Page v. City of Richmond, 218 Va. 844, 847, 241 S.E.2d 775, 777 (1978); City of Norfolk v. Lillard, 15 Va. App. 424, 426, 424 S.E.2d 243, 244-45 (1992). The presumption of causation provided by Code Sec. 65.2-402(B) is "overcome by a preponderance of evidence to the contrary," and, "[i]n the absence of competent evidence to the contrary, the statutory presumption controls and the claimant prevails." Lillard, 15 Va. App. at 426, 424 S.E.2d at 245. The law is well settled that [i]n order to rebut the presumption, it is not sufficient that the employer merely adduce evidence that the heart disease was not caused by the employment; the employer must establish by competent medical evidence a non-work-related cause to rebut or overcome the statutory presumption that causation exists. Fairfax Co. Fire and Rescue Dep't v. Mitchell, 14 Va. App. 1033, 1036-37, 421 S.E.2d 668, 670-71 (1992) (citing Virginia Dep't of State Police v. Talbert, 1 Va. App. 250, 253, 337 S.E.2d 307, 308 (1985)); see also Page, 218 Va. at 848, 241 S.E.2d at 777.

Code Sec. 65.2-402 provides that "heart disease . . . resulting in total or partial disability of [a police officer] . . . shall be presumed to be [an] occupational disease, suffered in the line of duty, . . . unless such presumption is overcome by a preponderance of competent evidence to the contrary." Thus, to rebut the presumption, an employer must establish by competent medical evidence a non-work-related cause of the employee's heart disease. City of Norfolk v. Lillard, 15 Va. App. 424, 430, 424 S.E.2d 243, 246-47 (1992). "[T]he showing of 'risk factors' alone does not rebut the statutory presumption and does not establish competent medical evidence of a non-work-related cause of the disabling disease." Lillard, 15 Va. App. at 429, 424 S.E.2d at 246. No medical evidence proved either that a non-work-related factor caused Coleman's heart attack or that work-related stress was not a contributing cause of his disability.

To recover compensation for an ordinary disease of life as an occupational disease, a claimant must establish "by clear and convincing evidence, to a reasonable medical certainty, that [his illness] arose out of and in the course of his employment." Code Sec. 65.2-401. However, the legislature "has accorded policemen who suffer from heart disease or hypertension preferential status." Department of State Police v. Talbert, 1 Va. App. 250,253, 337 S.E.2d 307, 308 (1985). Code Sec. 65.2-402 creates a rebuttable presumption that a causal connection exists between an individual's employment as a police officer and certain diseases. "A presumption is a rule of law that compels the fact finder to draw a certain conclusion . . . from a given set of facts." Martin v. Phillips, 235 Va. 523, 526, 369 S.E.2d 397, 399 (1988) (citing Simpson v. Simpson, 162 Va. 621, 641-42, 175 S.E. 320,329 (1934)). "The primary significance of a presumption is that it operates to shift to the opposing party the burden of producing evidence tending to rebut the presumption." Martin, 235 Va. at 526, 369 S.E.2d at 399. "[T]he effect of the presumption is to eliminate the need for a claimant to prove a causal connection between his disease and his employment." City of Norfolk v. Lillard, 15 Va. App. 424, 426, 424 S.E.2d 243,244-45 (1992). "In the absence of competent evidence to the contrary, the statutory presumption controls, and the claimant prevails." Fairfax County Fire & Rescue Dep't v. Mitchell, 14 Va. App. 1033, 1035, 421 S.E.2d 668, 670 (1992). To trigger the presumption, claimant need only prove his occupation and his disability from heart disease or hypertension, the diseases identified in Code Sec. 65.2-402. Once claimant has established his prima facie case, "[t]he presumption shifts the burden of going forward with the evidence from the claimant to his employer." Id. Proof of claimant's disability from heart disease or hypertension depends upon medical evidence.

Fairfax County Fire and Rescue Services v. Newman, 222 Va. 535, 281 S.E.2d 897 (1981), held that the causation presumptions now codified at Code Sec. 65.2-402 cast "the ultimate risk of nonpersuasion" upon the employer, 222 Va. at 541, 281 S.E.2d at 901. It is fundamental and well settled that the "risk of nonpersuasion" is a direct reference to the burden of persuasion. See Darden v. Murphy, 176 Va. 511, 518, 11 S.E.2d 579, 580 (1940) (stating that "the burden of proof in the sense of the risk of nonpersuasion" is distinguishable from "the burden of going forward with the evidence").

(See Supreme Court case above: City of Hopewell, et al. v. Michael W. Tirpak, Record No. 982126 ( June 11, 1999), WP Version, placing the burden on the employer to prove by a preponderance of the evidence that the claimant's disease was not caused by his employment, and there was a non-work-related cause of the disease.) The Court of Appeals had held that whether an employer has rebutted the causation presumption is determined by the commission in its role as fact finder after weighing the evidence offered by both parties on the issue of causation. because the causation presumption shifts both the burdens of production and persuasion to the employer, whether proof of a non-work-related cause is sufficient to rebut the presumption depends upon how the commission weighs the evidence presented by the parties. If the preponderance of the evidence produced by the parties indicates to the commission, the trier of fact, that the heart disease was caused by non-work-related factors and that there was no proximate causal connection between the disease and the employment, then the causation presumption is rebutted. A claimant who proves that the causation presumption applies to his or her claim is entitled to full benefits if there is affirmative evidence deemed persuasive by the commission that the employment was a contributing cause of the claimant's heart disease. Thus, if the preponderance of the evidence indicates to the commission that the claimant's heart disease had multiple causes, at least one of which is related to the employment, then the presumption that the heart disease was "suffered in the line of duty" is not rebutted. City of Hopewell v. Michael W. Tirpak, Record No. 1369-97-2 (July 28, 1998).

The purpose of the presumption provided by Code Sec. 65.2-401(B) is to establish a causal connection between, inter alia, disability from heart disease and the occupation of a state trooper. Page v. City of Richmond, 218 Va. 844, 847, 241 S.E.2d 775, 777 (1978); City of Norfolk v. Lillard, 15 Va. App. 424, 426, 424 S.E.2d 243, 244-45 (1992). The presumption of causation provided by Code Sec. 65.2-402(B) is "overcome by a preponderance of evidence to the contrary," and, "[i]n the absence of competent evidence to the contrary, the statutory presumption controls and the claimant prevails." Lillard, 15 Va. App. at 426, 424 S.E.2d at 245. The law is well settled that [i]n order to rebut the presumption, it is not sufficient that the employer merely adduce evidence that the heart disease was not caused by the employment; the employer must establish by competent medical evidence a non-work-related cause to rebut or overcome the statutory presumption that causation exists. Fairfax Co. Fire and Rescue Dep't v. Mitchell, 14 Va. App. 1033,1036-37, 421 S.E.2d 668, 670-71 (1992) (citing Virginia Dep't of State Police v. Talbert, 1 Va. App. 250, 253, 337 S.E.2d 307, 308 (1985)); see also Page, 218 Va. at 848, 241 S.E.2d at 777. The issue here is whether the employer must establish a non-work-related cause to the exclusion of work-related factors. In Mitchell, the Court of Appeals held that where the employer's "rebuttal evidence fail[s] to exclude a work-related factor as a cause of the heart disease, the finding of the commission that the employer failed to rebut the presumption in claimant's favor is conclusive and binding on appeal." Mitchell, 14 Va. App. at 1034, 421 S.E.2d at 669; see also Talbert, 1 Va. App. at 253, 337 S.E.2d at 308; County of Amherst v. Brockman, 224 Va. 391, 399,297 S.E.2d 805, 809-10 (1982) (commission's award affirmed if rebuttal evidence does not exclude stress as possible "contributing cause").  Here, employer presented significant evidence of non-work-related factors which may have contributed to the claimants' conditions, but it did not exclude the claimants' work as a contributing factor. In proving causation in a workers' compensation case where the evidence demonstrates two or more potential causative factors, one of two conclusions follows. Either, a combination of factors contributed to cause the disability; or, one of the factors caused the disability to the exclusion of the others. The "two causes rule" addresses those cases "where a disability has two causes: one related to the employment and one unrelated." Smith v. Fieldcrest Mills, Inc., 224 Va. 24, 28, 294 S.E.2d 805, 808 (1982) (quoting Bergmann v. L & W Drywall, 222 Va. 30, 32, 278 S.E.2d 801, 803 (1981)); see also Shelton v. Ennis Business Forms, 1 Va. App. 53, 55, 334 S.E.2d 297, 299 (1985). Under the two causes rule, "full benefits [are] allowed when it is shown that `the employment is a contributing factor.'"   Smith, 224 Va. at 28-29, 294 S.E.2d at 808 (quoting Bergman, 222 Va. at 32, 278 S.E.2d at 803); see also Shelton, 1 Va. App. at 55, 334 S.E.2d at 299. The "more probable than not rule," addresses those cases where only one of a number of possible factors caused the disability. See id. Under the more probable than not rule, for the disability to be compensable, it must be more probable than not that it was caused by the work-related factor. Id. That is, a preponderance of evidence must show that work was the cause of the disability. Id. As in Smith and Bergmann, the evidence in this case proved that a number of factors contributed to the development of claimants' conditions. Under the "two causes" rule, causation, and therefore compensability, is established when it is shown that work contributed to the disability. For this reason,  in a case where the evidence demonstrates that multiple factors, including job stress, contributed to the development of a police officer's heart disease, the employer must exclude  work-related stress as a contributing factor to rebut the presumption of causation.  Here, both the deputy commissioner and the full commission found that employer's evidence failed to exclude job stress as a contributing factor. Cf. Doss v. Fairfax County Fire Dept., 229 Va. 440, 441-42, 331 S.E.2d 795, 795-96 (1985) (employer's evidence established a non-work-related cause to the exclusion of work-related factors); Cook v. City of Waynesboro, 225 Va. 23, 28-30, 300 S.E.2d 746, 748-49 (1983) (same). Finch Weston Duffy, et al. v. Commonwealth of Virginia/Department of State Police, Record No. 0945-95-4 (April 9, 1996).

Sec. 65.2-402(C) presumption requires proof of cause. After 30 years with the fire department, Claimant was diagnosed with prostate cancer, an ordinary disease of life of unknown etiology.  Claimant's evidence, however, documented an exposure to cadmium, a substance identified as carcinogenic by the International Agency for Research on Cancer (IARC), as a suspected cause of prostate cancer. Code Sec. 65.2-402(C), provides, in pertinent part, that “prostate cancer, caused by a documented contact with a toxic substance that a . . . fire fighter . . . has encountered in the line of duty and that causes . . . any health condition or impairment[,] . . . shall be presumed to be an occupational disease, suffered in the line of duty, that is covered by this title, unless such presumption is overcome by a preponderance of competent evidence to the contrary.  For the purposes of this section, a ‘toxic substance’ is one which is a known or suspected carcinogen, as defined by the International Agency for Research on Cancer [IARC], and which causes, or is suspected to cause, . . . prostate . . . cancer.” Code Sec. 65.2-402 (C) explicitly provides that the presumption of occupational disease applies to prostate cancer "that is caused by a documented contact with a toxic substance." Claimant was not entitled to the statutory presumption of occupational disease because he did not prove that exposure to the toxic substance cadmium "caused or contributed to cause, his prostate cancer." Newell E. Whitehead, Jr. v. City of Portsmouth FD, Record No. 2975-98-1 (July 27, 1999). WP Version.

    The full commission erred in finding that the employer had carried its burden of proving in each case, by a preponderance of the evidence, that Medlin's and Vass' work was not a proximate cause of their heart disease.
    In this matter of first impression before the Virginia appellate courts, the court addressed the question of whether testimony which only generally refutes the existence of a causal relationship between work-related stress and heart disease rebuts the statutory presumption established under Code Sec. 65.2-402(B). The court held that testimony of this nature is not probative on the issue.        
    Code Sec. 65.2-402(B) provides the following presumption in certain workers' compensation cases: Hypertension or heart disease causing the death of, or any health condition or impairment resulting in total or partial disability of [various specified law enforcement personnel] shall be presumed to be occupational diseases, suffered in the line of duty, that are covered by this title unless such presumption is overcome by a preponderance of competent evidence to the contrary. The statute requires that in order for the presumption to apply, the employee must have undergone a pre-employment physical examination, if requested by the employer, and must have been found to be free of hypertension or heart disease at the time of that examination. Code Sec. 65.2-402(D). 
    Medlin proved that the presumption applied to him. He was a member of the Henrico County Police Department at all times relevant to this claim. Although Medlin began his employment with the County in 1974, he was not asked to undergo a physical examination until 1976. At the time of the examination, he was found to be free of heart disease and hypertension. Finally, Medlin was diagnosed with heart disease in May, 1998 and was also found to be suffering from hypertension at that time. 
    Likewise, Vass proved the presumption applied to him. Vass has been employed by the Henrico County Police Department since 1974. In 1976, he was found to be free of heart disease and hypertension following a physical examination conducted at the direction of his employer. Finally, Vass was diagnosed with hypertension and heart disease in February, 1997. 
    After the claimant establishes that he is entitled to the presumption, the burden shifts to the employer to refute the presumption.
Fairfax County Fire and Rescue Dept. v. Mitchell, 14 Va. App. 1033, 1035, 421 S.E.2d 668, 670 (1992). The employer must prove, by a preponderance of the evidence, two factors: (1) a non-work-related cause for the heart disease; and (2) that work was not a cause of the claimant's heart disease. Bass v. City of Richmond Police Dept., 258 Va. 103, 112-13, 515 S.E.2d 557, 561-62 (1999).
     Medlin conceded that, in addition to work-related causes, there were non-work-related causes that contributed to his heart disease. Vass likewise conceded that both work-related and non-work-related causes contributed to his heart disease. Therefore, because a non-work-related cause was established, the remaining question is whether the employer proved, by a preponderance of competent evidence, that the work that Medlin and Vass performed as police officers did not contribute to their heart disease. 
    In finding that the employer had proved Medlin's work was not a cause of his heart disease, the commission relied, in part, on the testimony of Dr. Hess. Dr. Hess concluded that, as a general matter, occupational stress does not cause heart disease. In Vass' case, the commission relied, in part, on the testimonies of Drs. Hess and Seides in finding the employer had proved Vass' work was not a cause of his heart disease. Both doctors testified that, as a general matter, occupational stress is not linked to the development of heart disease. 
    The court found that because of the legislatively created presumption to the contrary, Dr. Hess' and Dr. Seides' opinions regarding the relationship between occupational stress and heart disease were of no probative value to the issues in these cases. See Page v. City of Richmond, 218 Va. 844, 847, 241 S.E.2d 775, 777 (1978). Code Sec. 65.2-402 "has long been recognized as a remedial statute, enacted by the legislature to overcome the difficulty that a [police officer] would otherwise have in proving causation." City of Norfolk v. Lillard, 15 Va. App. 424, 430, 424 S.E.2d 243, 247 (1992). In enacting the statute, "[t]he legislature knew that the causes of . . . cardiac diseases are unknown and that the medical community is split regarding the impact of stress and work environment on these diseases." Fairfax County Fire and Rescue Services v. Newman, 222 Va. 535, 540, 281 S.E.2d 897, 900 (1981); see also Stephens v. Workmen's Compensation Appeals Board, 20 Cal. App. 3d 461, 465 (Cal. Ct. App. 1971); Robertson v. North Dakota Workers' Compensation Bureau, 616 N.W.2d 844, 854 (N.D. 2000); Sperbeck v. Dept. of Industry, Labor & Human Relations, 174 N.W.2d 546, 548 (Wis. 1970). By enacting the statutory presumption, the General Assembly resolved the split in medical opinions in favor of the employee and adopted the presumption that the stress of working as a law enforcement officer causes or contributes to the development of heart disease. See Stephens, 20 Cal. App. 3d at 465; Linnell v. City of St. Louis Park, 305 N.W.2d 599, 601 (Minn. 1981); Cunningham v. City of Manchester Fire Dept., 525 A.2d 714, 718 (N.H. 1987); Robertson, 616 N.W.2d at 854.
    Testimony which merely refutes the premise of such a legislatively enacted presumption does not constitute proper evidence in rebuttal.
Where the General Assembly has concluded that there is a causal link between stress and heart disease, it is not for the commission or the courts to reconsider the issue, for to do so would defeat the intentions of the legislature. It thus follows that, "[i]t is impermissible for the [commission] to accept the opinion of a physician so disposed as the basis for disallowing a claim." Stephens, 20 Cal. App. 3d at 467; Swanson v. City of St. Paul, 526 N.W.2d 366, 368 (Minn. 1995); Cunningham, 525 A.2d at 718; Robertson, 616 N.W.2d at 854. Stated otherwise, the employer may not, in effect, "repeal" the statute "by seeking out a doctor whose beliefs preclude its possible application." Stephens, 20 Cal. App. 3d at 467; see also Linnell, 305 N.W.2d at 601; Sperbeck, 174 N.W.2d at 289. In Sperbeck, the court noted that "[e]vidence which only attacks the rationale of the statute . . . does nothing more than question the wisdom of the legislature." Sperbeck, 174 N.W.2d at 289. If the majority of the medical community concludes there is no link between stress and heart disease, the employer's remedy is to go back to the General Assembly. Sperbeck, 174 N.W.2d at 289. Accordingly, evidence that merely rebuts generally the underlying premise of the statute, which establishes a causal link between stress and heart disease, is not probative evidence for purposes of overcoming the presumption. The commission therefore erred when it relied, in part, on the testimonies of Dr. Hess and Dr. Seides, which did no more than refute the conclusion of the Virginia General Assembly. Because the weight the commission assigned to Dr. Hess' and Dr. Seides' opinions in reaching its decisions is unclear, both cases must be remanded to the commission to determine whether the employer has sufficiently rebutted the presumption in light of the remaining probative evidence in these cases. See Virginia Dept. of State Police v. Talbert, 1 Va. App. 250, 253, 337 S.E.2d 307, 308 (1985) ("We do not review the weight or preponderance of the evidence nor the credibility of the witnesses, except to consider whether there exists sufficient credible evidence to sustain the findings.").
    In City of Portsmouth Sheriff's Dept. v. Clark, 30 Va. App. 545, 518 S.E.2d 342 (1999). In Portsmouth, the court held that proof of a "risk factor" alone does not establish a non-work-related cause for a claimant's heart disease. Portsmouth, 30 Va. App. at 554, 518 S.E.2d at 346. The court found that the employer in that case had failed to prove that the claimant's family history risk factor actually caused his disease. Id.  The commission erred in its application of the holding in Portsmouth. Contrary to the commission's conclusion that "Dr. Schwartz speaks only of 'risk factors,'" the record shows that in Vass' case, Dr. Schwartz opined that Vass' occupational stress was a risk factor that "can be considered a contributing factor" in the development of his disability. Because it erroneously applied the holding in Portsmouth, the commission did not consider what weight, if any, it would accord Dr. Schwartz's opinion, as it is required to do. Hungerford Mechanical Corp. v. Hobson, 11 Va. App. 675, 677, 401 S.E.2d 213, 215 (1991) ("Medical evidence is not necessarily conclusive, but is subject to the commission's consideration and weighing."). On remand, the commission will have to reconsider Dr. Schwartz's opinion, together with all the remaining evidence in this case, in light of this holding.
    The commission also erred, as a matter of law, in concluding that because Drs. Bennett and Matthews stated that Medlin's work was a contributing factor in "the development, acceleration and/or aggravation" of Medlin's heart disease, that the disease must have pre-existed his employment. The commission similarly erred in Vass' case  with respect to the commission's treatment of Dr. Overmeyer's opinion.
    In both opinions, the commission cited Ashland Oil Co. v. Bean, 225 Va. 1, 300 S.E.2d 739 (1983), for the proposition that "[i]f work merely aggravates a disease, then the disease must have pre-existed the employment. Work, then, could not have been the originating cause of the disease, and the aggravation would not be compensable as an occupational disease." The Virginia Supreme Court held in Ashland Oil that an employee cannot recover "for aggravation of ordinary diseases of life," id. at 3, 300 S.E.2d at 740. Here, the uncontroverted evidence showed that Medlin and Vass began their employment in 1974 and were found to be free of heart disease and hypertension in 1976, following a physical examination conducted at the direction of the County. Therefore, Medlin's and Vass' conditions did not pre-exist their employment. In addition, the Code Sec. 65.2-402 presumption provides that if the employee can prove he was free of heart disease or hypertension at the beginning of his employment, his disease will be presumed to be an occupational disease. Therefore, the commission erred, as a matter of law, in misinterpreting Ashland Oil, and in concluding that Medlin's and Vass' disease pre-existed their employment.
    Because the commission improperly considered Dr. Hess' and Dr. Seides' opinions in reaching its decisions, both cases were remanded to the commission for reconsideration of the remaining evidence. James Isaac Medlin, Jr. v. County of Henrico Police, 34 Va. App. 396, 542 S.E.2d 32 (2001), Record No. 1047-00-2 (January 27, 2001); Stephen Douglas Vass v. County of Henrico Police, Record No. 1048-00-2 (January 27, 2001).WP Version.

    Medlin II. Medlin I (Medlin v. County of Henrico Police, 34 Va. App. 396, 542 S.E.2d 33 (2001)) does not require exclusion of expert testimony and opinion that is inconsistent with the Code Sec. 65.2-402 presumption.  That contention misreads Medlin IMedlin I holds only that "evidence that merely rebuts generally the underlying premise of the statute, which establishes a causal link between stress and heart disease, is not probative evidence for the purposes of overcoming the presumption."  Medlin I, 34 Va. App. at 407, 542 S.E.2d at 39 (emphasis added).  Under this holding, expert opinion that merely discounts the presumption is non-probative and irrelevant to refute the presumption.  To refute the presumption, evidence must deny that work was a cause or risk factor of the claimant's heart disease, see Bristol City Fire Dep't and Virginia Mun. Group Self-Ins. Ass'n v. Maine, 35 Va. App. 109, 117, 542 S.E.2d 822, 826 (2001), and must attribute the claimant's heart disease to a specific, non-work-related cause.
    The commission did not exceed its authority by re-examining the evidence on remand.  The direction of the Court of Appeals in Medlin I refutes this argument.  Holding that the commission erred in relying on Dr. Hess's testimony, the court gave the following instruction:  Because the weight the commission assigned to Dr. Hess's . . . opinions in reaching its decisions is unclear, we remand . . . to the commission to determine whether the employer has sufficiently rebutted the presumption in light of the remaining probative evidence . . . .Medlin I, 34 Va. App. at 408, 542 S.E.2d at 39.
    The law of the case doctrine also does not apply.  The law of the case doctrine provides that "[w]here there have been two appeals in the same case, between the same
parties, and the facts are the same, nothing decided on the first appeal can be re-examined on a second appeal."  Uninsured Employer's Fund v. Thrush, 255 Va. 14, 18, 496 S.E.2d 57, 58-59 (1998).  This doctrine does not apply to the case before us.  No determinations from the first case carried forward to this case.  The commission's original factual determinations were not addressed in Medlin I.  The case was remanded because those factual determinations were based on an erroneous application of law.
    The commission did not err in finding that the Code Sec. 65.2-402(B) presumption was not rebutted.  Medlin was free of heart disease and hypertension when he began working for the Henrico County Police Department in 1976.  Expert testimony that his May 2, 1997 attack and his heart disease were stress-related supports the presumption and the
commission's decision to award him benefits.  "Decisions of the commission as to questions of fact, if supported by credible evidence, are conclusive and binding on this Court."  Manassas Ice, 13 Va. App. at 229, 409 S.E.2d at 826.  "The fact that
contrary evidence may be found in the record is of no consequence if credible evidence supports the commission's finding."  IdCounty of Henrico Police v. James Isaac Medlin, Jr.Record No. 1891-01-2 (March 26, 2002). WP Version.

    The Workers' Compensation Commission ("commission") did not err in awarding temporary total and medical benefits to claimant. Employer did not rebut the presumption afforded by Code Sec. 65.2-402 and claimant presented evidence sufficient to prove that his heart disease arose out of and in the course of his employment.
    Claimant began work as a firefighter for employer in 1971. He was not given a pre-employment physical; however, the results of all later physicals done prior to his heart attack were within normal limits. Claimant described his employment history and the stressful situations he experienced as a firefighter. During the time period of September 27-30, 1996 claimant suffered a heart attack. He was treated by Dr. Mark A. Borsch, who performed two separate angioplasties. Dr. Borsch released claimant to return to full duty employment on March 31, 1997. The parties stipulated that claimant: (1) was entitled to claim the presumption afforded by Code Sec. 65.2-402; (2) was employed with Bristol City Fire Department at all times relevant to this case; (3) suffered a heart attack; and (4) was disabled for the period claimed.
    Bass v. City of Richmond Police Department, 258 Va. 103, 515 S.E.2d 557 (1999) clarified the decision in Augusta County Sheriff's Department v. Overbey, 254 Va. 522, 492 S.E.2d 631 (1997), and set out a two-prong test employers must meet to overcome the presumption of Code Sec. 65.2-402. "To overcome the presumption the employer must show, by a preponderance of the evidence, both that 1) the claimant's disease was not caused by his employment, and 2) there was a non-work related cause of the disease." Bass, 258 Va. at 112-13, 515 S.E.2d at 561-62. The commission found that employer failed to meet the second prong of the Bass test.
    Regarding this prong, both the claimant's treating physician, Dr. Borsch, and the employer's expert, Dr. Hess, identified non-work related causes of the claimant's heart disease. Dr. Seides, while identifying some risk factors, failed to specifically state that these risk factors caused the claimant's disease. On the other hand, Dr. Schwartz excluded both family history and elevated cholesterol as risk factors. Admittedly, Dr. Schwartz speaks in terms of statistical correlates vice [sic] causative factors. Thus, a positive identification by Dr. Schwartz of a risk factor may not constitute persuasive evidence of a cause of a disease. The converse, however, is not true. No physician has identified a cause of the claimant's disease without first finding the causative factor to be a risk factor. Accordingly, Dr. Schwartz' opinion that family history and cholesterol are not risk factors constitutes evidence that these factors are not causes of the disease.
    The medical opinions of Drs. Hess and Seides simply attempt to discount the presumption of Code Sec. 65.2-402, rather than evaluating whether work was a cause or risk factor of the heart disease. We have recently held "that because of the legislatively created presumption to the contrary, Dr. Hess' and Dr. Seides' opinions regarding the relationship between occupational stress and heart disease were of no probative value to the issues in these cases." Medlin v. County of Henrico Police, 34 Va. App. 396, 40, 542 S.E.2d 33, 38-39 (2001). Testimony which merely refutes the premise of such a legislatively enacted presumption does not constitute proper evidence in rebuttal. Where the General Assembly has concluded that there is a causal link between stress and heart disease, it is not for the commission or the courts to reconsider the issue, for to do so would defeat the intentions of the legislature. Id. at ___, ___ S.E.2d at ___. "Evidence that merely rebuts generally the underlying premise of the statute, which establishes a causal link between stress and heart disease, is not probative evidence for purposes of overcoming the presumption." Id. at ___, ___ S.E.2d at ___.Therefore, the commission did not err in giving greater weight to the medical opinion of Dr. Schwartz. He addressed claimant's situation specifically and opined that his family history and cholesterol levels were not risk factors in the development of his heart disease. Bristol City Fire Dep't. v.

       Application of the presumption to claimant's virally induced heart disease, coupled with evidence that work-related stress made claimant more susceptible to the virus and resulting heart disease, is constitutional under Fairfax County Fire & Rescue Services v. Newman, 222 Va. 535, 281 S.E.2d 897 (1981).   Quoting its earlier decision in Crenshaw v. Commonwealth, 219 Va. 38, 42, 245 S.E.2d 243, 246 (1978), it held that for the application of such a presumption to be constitutional, "(1) a 'natural and rational' evidentiary nexus must exist between the fact proved and the fact presumed and (2) the presumption must be rebuttable."  Newman, 222 Va. at 539-40, 281 S.E.2d at 900. In claimant's case, a "natural and rational nexus" exists between law enforcement occupations and heart disease in general.  Id. at 540, 281 S.E.2d at 900.  As the Court observed in Newman, the primary causes of many cardiac diseases are unknown, and the medical community is split regarding the impact of stress and work environment on these diseases.  Id.; see also, e.g., City of Portsmouth Sheriff's Dep't v. Clark, 30 Va. App. 545, 553-56, 518 S.E.2d 342, 346-47(1999)(discussing "risk factors" for coronary artery disease and noting absence of evidence of definitive causes of such disease); City of Richmond Fire Dep't v. Dean, 30 Va. App. 306, 312, 516 S.E.2d 709, 712 (1999) (noting that twenty to thirty percent of "heart block" cases are of unknown origin); Duffy v. Dep't of State Police, 22 Va. App. 245, 247, 468 S.E.2d 702, 703 (1996) (noting evidence that stress contributed to development of police officer's coronary artery disease).  The jobs of law enforcement officers, like firefighters, are often stressful.  Because at least some members of the medical community believe stress is a factor in the development of heart disease, a natural and rational nexus exists between the occupation and the disease, rendering Code Sec. 65.2-402(B) constitutional on its face.
        Further, a "natural and rational nexus" exists between claimant's duties as a police officer and cardiomyopathy, the specific heart disease from which he suffers.  Although some of the evidence was conflicting, claimant presented testimony accepted by the commission that his virally induced cardiomyopathy was work-related because it was more likely than not that he contracted it during close interpersonal contact required by his employment and because the stress inherent in his job made him more susceptible to contracting the virus.  Thus, although heart disease that is virally induced may be unusual, a "natural and rational" nexus exists between the presumption and the fact to be proved under the facts of this case.
        Finally, the presumption was not irrebuttable under the facts of this case.  Here, as in Newman, employer's inability to rebut the presumption resulted from the shortcomings of medical science, i.e., the difficulties inherent in trying to pinpoint the precise source from which one has contracted a virus and in determining the impact of job stress on the ability of one's immune system to resist such a virus.  The employer's difficulties in rebutting the presumption did not result from an evidentiary rule which, "for all practical purposes," excluded relevant evidence, which was the case with the presumption found unconstitutional in Crenshaw, 219 Va. at 42, 245 S.E.2d at 246. Thus, application of the presumption was not unconstitutional under the facts of this case.
        The evidence that claimant's heart disease resulted from a virus did not prove a non-work-related cause of the heart disease sufficient to rebut the presumption because the evidence supported a finding that  claimant could have contracted the virus, and more probably than not did contract it, through work-related exposure and that claimant's job stress increased his susceptibility to the virus.  Thus, the evidence supports the commission's conclusion that employer failed to prove a non-work-related cause. Employer failed to rebut the presumption.  The legal principles are simple.  Claimant established a prima facie case of coverage by proving he was a police officer and that he experienced a disability resulting from heart disease.  City of Norfolk v. Lillard, 15 Va. App. 424, 427, 424 S.E.2d 243, 245 (1992).  The burden then shifted to employer to prove by a preponderance of the evidence both that (1) the claimant's disease was not caused by his employment and (2) a non-work-related cause of the disease existed.  Bass v. City of Richmond Police Department, 258 Va. 103, 115, 515 S.E.2d 557, 563 (1999).  Employer failed to meet that burden.
        The commission found, as employer concedes it was entitled to do, that claimant's heart disease was caused by a virus.  The mere fact that claimant could have contracted the virus which caused his cardiomyopathy from a source unrelated to his employment is insufficient to establish the cause was, in fact, non-work-related.  Further, evidence before the commission indicated that the nature of claimant's work as a police officer in fact increased his risk of contracting the type of "community acquired" virus which caused his heart condition because it both (1) placed him in greater contact with the public and with their various bodily fluids and (2) increased the overall level of stress in his life, thereby rendering him more susceptible to all viruses.
        In arguing the constitutional question on brief, employer concedes that even without the presumption, a claimant may establish a connection between his employment and "all manner of viruses and bacterial infections."  Thus, employer's contention that the unknown, "community acquired" virus which caused claimant's cardiomyopathy was inherently non-work-related is disingenuous.  Carried to its logical extreme, employer's argument would prevent coverage for any disability resulting from a virus spread among the general population, even if a claimant could prove the required nexus between the virus and his employment.  If the legislature had wished to exclude from the coverage of the presumption those forms of heart disease with known causes or viral causes, it could have done so, but it did not.  Thus, credible evidence supports the commission's decision. Town of Purcellville Police v. Bromser-Kloeden, Record No. 2335-00-4 (April 10, 2001). WP Version.

    The commission did not err in finding that claimant had heart disease and did not err in holding that employer failed to rebut the statutory presumption of Code Sec. 65.2-402(B) that claimant's heart condition was an occupational disease covered by the Workers' Compensation Act.
    Claimant was a fifty-three-year-old police officer who had been on the force for approximately twenty six years. Thirty minutes after carrying a television into his home, he died. Without examining the body, claimant's
family physician for thirty years, Dr. Forbes, executed the death certificate, indicating that Coffey died as a result of acute myocardial infarction.  No autopsy was performed or requested. Claimant had not been diagnosed with heart disease prior to his death.
    The first issue is whether the evidence is sufficient to prove that claimant died as a result of a heart attack or heart disease.  See Code Sec. 65.2-402(B);  Page v. City of Richmond, 218 Va. 844, 847, 241 S.E.2d 775, 777 (1978). Six physicians rendered opinions as to the cause of claimant's death.  See Code Sec. 8.01-401.1 ("[A]ny expert witness may give testimony and render an opinion or draw inferences from facts, circumstances, or data made known to . . . such witness . . . .  The expert may testify in terms of opinion or inference and give his reasons therefor without prior disclosure of the underlying facts or data . . . ."); Cox v. Oakwood Mining, Inc., 16 Va. App. 965, 434 S.E.2d 904 (1993) (applying Code Sec. 8.01-401.1). "An expert's opinion which is neither based upon facts within his own knowledge nor established by other evidence is speculative and possesses no evidential value."  Gilbert v. Summers, 240 Va. 155, 160, 393 S.E.2d 213, 215 (1990).  However, a doctor's expert medical opinion is not speculative if based on an accurate understanding of the relevant facts.  See id.; cf. Clinchfield Coal Co. v. Bowman, 229 Va. 249, 252, 329 S.E.2d 15,16 (1985) (per curiam) (holding that a doctor's medical opinion was not credible when based upon a faulty premise); Spruill v. Commonwealth, 221 Va. 475, 479, 271 S.E.2d 419, 421 (1980) (stating that a medical opinion is speculative if based on a "possibility" but admissible and sufficient if based on a "reasonable probability"); Circuit City Stores, Inc. v. Scotece, 28 Va. App. 383, 387-88, 504 S.E.2d 881, 883-84 (1998) (adopting standard for admissibility of medical evidence articulated in Spruill).  In rendering their opinions, the physicians had access to claimant's medical records, the records of the emergency personnel who attempted to resuscitate claimant, and claimant's wife's deposition detailing the facts and circumstances immediately preceding claimant's death.  Several doctors attributed claimant's death to heart disease or conditions associated with it.  Although employer's experts advanced alternative causes for claimant's death, the physicians stated that such causes other than heart disease were unusual.  Therefore, credible evidence supports the commission's finding that claimant died of heart disease.
    The second issue is whether the employer rebutted the presumption of Code Sec. 65.2-402(B) that once the claimant had shown that the law enforcement official died as a result of heart disease, the heart disease shall be presumed to be an occupational disease unless this presumption is sufficiently rebutted by employer. The Supreme Court recently held that [t]o overcome the presumption [contained in Code Sec. 65.2-402(B)], the employer must show, by a preponderance of the evidence, both that 1) the [employee's] disease was not caused by his  employment, and 2) there was a non-work-related cause of the disease.  Thus, if the employer does not prove by a preponderance of the evidence both parts of this two-part test, the employer has failed to overcome the statutory presumption. Bass v. City of Richmond Police Department, 258 Va. 103, 114, 515 S.E.2d 557, 562-63 (1999) (citations omitted). Although employer's experts presented evidence of non work-related causes of claimant's heart disease, the the medical evidence was in substantial conflict.  Two of employer's experts impermissibly attempted to rebut the legislative presumption by negating any causal link between occupational stress and heart disease, and, thus, is not probative rebuttal evidence.  Medlin v. County of Henrico Police, 34 Va. App. 396, 40, 542 S.E.2d 33, 38-39 (2001). Although another employer expert conceded that stress was a "minor factor" in this case, he failed to exclude it as a significant factor causing his heart disease.  Accordingly, the commission did not err in finding that employer's rebuttal evidence failed to exclude claimant's occupational stress as a cause of his heart disease.  City of Waynesboro Police v. Sharon Coffey, etc.,  Record No. 1456-00-2 (April 17, 2001). WP Version

 

VIRGINIA BIRTH-RELATED NEUROLOGICAL INJURY COMPENSATION ACT

    The commission did not err when it found that the Virginia Birth-Related Neurological Injury Compensation Program (Program) failed to rebut the statutory presumption contained in Code Sec. 38.2-5008(A). The Virginia Birth-Related Neurological Injury Compensation Act (Act) was established to provide compensation to families whose neonates suffer "birth-related neurological injuries." See Code Secs. 38.2-5000 through 38.2-5021. Code Sec. 38.2-5001 defines a "birth-related neurological injury" as follows:          "Birth-related neurological injury" means injury to the brain or spinal cord of an infant caused by the deprivation of oxygen or mechanical injury occurring in the course of labor, delivery or resuscitation in the immediate post-delivery period in a hospital which renders the infant permanently motorically disabled and (i) developmentally disabled or (ii) for infants sufficiently developed to be cognitively evaluated, cognitively disabled.
    Code Sec. 38.2-5008(A) provides as follows: A rebuttable presumption shall arise that the injury alleged is a birth-related neurological injury where it has been demonstrated, to the satisfaction of the Virginia Workers' Compensation Commission, that the infant has sustained a brain or spinal cord injury caused by oxygen deprivation or mechanical injury, and that the infant was thereby rendered permanently motorically disabled and (i) developmentally disabled or (ii) for infants sufficiently developed to be cognitively evaluated, cognitively disabled. The presumption set forth in Code Sec. 38.2-5008(A) must be construed according to the "Morgan theory." Therefore, the presumption set forth in Code Sec. 38.2-5008(A) shifts to the Program both the burden of production and the burden of persuasion on the issue of causation. Tommy, who suffers from severe cerebral palsy, was born on March 30, 1989, after twenty-seven weeks gestation.  The Program has not carried its burden. Notwithstanding the opinions of Dr. Seeds, writing on behalf of the panel, and Dr. Partridge, it is clear that Tommy suffered from oxygen deprivation during the birth-process -- he was not breathing when he was born, the umbilical cord was wrapped around his neck, and he required seven minutes of CPR to resuscitate him. Although his condition improved for a few moments after resuscitation, he immediately decompensated in intensive care and for several hours the doctors were unable to obtain acceptable oxygen levels. As to the contribution of this oxygen deprivation to his disability, Dr. Brennan, a neurologist, and Dr. Bryant, who treated Tommy shortly after he was born, both attributed his problems in part to asphyxia. Dr. Brennan specifically referred to "initial asphyxia" as contributing to his neurological condition. Dr. Wells, another treating physician, simply described Tommy's cerebral palsy as a "birth injury." Dr. Partridge's report indicates that he was trying to discern the "asphyxia causation." Virginia Birth-Related Neur. Inj. Comp. v. Ada Young, 34 Va. App. 306, 311, 541 S.E.2d 298, 301 (2001), Record No. 0827-00-2 (February 13, 2001). WP Version.  

    The commission did not err in assuming jurisdiction and deciding his claim without affording the claimant legal counsel; but the commission erred in holding that the Birth-Related Neurological Compensation Program (the Program) had successfully rebutted the presumption set forth in Code Sec. 38.2-5008(A)(1).
    The commission's failure to appoint legal counsel to prosecute claimant's petition and a guardian ad litem to protect claimant's interests did not deny it jurisdiction to decide his claim.  The commission properly afforded claimant his procedural rights under the Act and that it had jurisdiction to decide his claim.
    The Act provides monetary relief to claimants who have sustained a "[b]irth-related neurological injury," which is defined as injury to the brain or spinal cord of an infant caused by the deprivation of oxygen or mechanical injury occurring in the course of labor, delivery or resuscitation in the immediate post-delivery period in a hospital which renders the infant permanently motorically disabled and (i) developmentally disabled or (ii) for infants sufficiently developed to be cognitively evaluated, cognitively disabled . . . [and which] disability [causes] the infant to be permanently in need of assistance in all activities of daily living. Code Sec. 38.2-5001. Recognizing the difficulty in proving when such an injury was sustained, the legislature enacted a presumption to assist potential claimants in obtaining benefits. Code Sec. 38.2-5008(A)(1) provides, in pertinent part, as follows: A rebuttable presumption shall arise that the injury alleged is a birth-related neurological injury where it has been demonstrated, to the satisfaction of the Virginia Workers' Compensation Commission, that the infant has sustained a brain or spinal cord injury caused by oxygen deprivation or mechanical injury, and that the infant was thereby rendered permanently motorically disabled . . . . If either party disagrees with such presumption, that party shall have the burden of proving that the injuries alleged are not birth-related neurological injuries within the meaning of the chapter. This is a "Morgan theory" presumption, which shifts "'both the burden of production and the burden of persuasion on the factual issue in question to the party against whom the presumption operates.'" Virginia Birth-Related Neurological Injury Compensation Program v. Young, 34 Va. App. 306, 311, 541 S.E.2d 298, 301 (2001).
    The Code Sec. 38.2-5008(A)(1) presumption is stated in essentially the same terms as the heart-lung presumption of Code Sec. 65.2-402(A), (B).  Thus, to defeat the Code Sec. 38.2-5008(A)(1) presumption, the Program must prove, to a reasonable degree of medical certainty, see Augusta County Sheriff's Dep't v. Overbey, 254 Va. 522, 527, 492 S.E.2d 631, 634 (1997), both (1) that the claimant's brain or spinal cord injury did not occur "in the course of labor, delivery or resuscitation in the immediate post-delivery period in a hospital" and (2) that there was a specific, non-birth-related cause of the injury.
   
No physician concluded, to a reasonable degree of medical certainty, that claimant's injuries did not occur at birth.  None of the medical opinions was stated to a reasonable degree of medical certainty. The three-physician panel concluded that claimant's "prompt response to resuscitation and his early neonatal course are inconsistent with birth-related neurological injury," but did not state this opinion to a reasonable degree of medical certainty.
    Assuming arguendo that the evidence supports a finding that claimant's injuries did not occur at birth, it fails to prove, to a reasonable degree of medical certainty, a specific, non-birth-related cause.  None of the medical opinions identified, to a reasonable degree of medical certainty, a non-birth-related cause of claimant's condition.
    The evidence failed, as a matter of law, to support the commission's holding that the Program had rebutted the Code Sec. 38.2-5008(A)(1) presumption.  Thus, the presumption carried claimant's burden of proof, and he is entitled to an award of benefits under the Act.  Devin M. Coffey, An Infant v. Virginia Birth-Rel. Neurolological Injury ProgramRecord No. 0529-01-4 (January 29, 2002). WP Version.

The commission did not err when it found claimant's claim did not meet the requirements of Code Sec. 65.2-406 because he filed the claim more than two years after he received a diagnosis of an occupational disease.  Claimant began working for the York County Fire and Rescue Department in 1973.  Claimant remained employed with the Fire and Rescue Department until 1999.  He filed a claim for benefits on October 21, 1999, alleging he had contracted an occupational disease, hypertension.
    In a 1995 examination claimant had a blood pressure reading of 190/100.  He was diagnosed with "hypertension, stage II."  Dr. Hollingsworth placed claimant on hypertension medicine, indicating he would discuss treadmill tests with the fire chief "before this patient can be cleared for the Fire Department."  On January 23, 1996, Dr. Bryant examined claimant. Dr. Bryant confirmed Dr. Hollingsworth's diagnosis of "hypertension" and again prescribed hypertension medication.  Claimant's blood pressure was 221/110.  On January 25, 1996 Dr. Bryant recommended the same hypertension medication, but at an increased dosage, and advised claimant "he would not be able to work if the [blood pressure] was not well controlled."  Dr. Bryant listed claimant's primary problem as "severe hypertension with poor compliance."  Claimant received follow up treatments for hypertension and related illnesses with Dr. Bryant on February 2, 1996, February 8, 1996, March 5, 1996, May 29, 1996, and February 25, 1997.  On January 13, 1998 the doctor diagnosed severe hypertension.  Dr. Bryant also had a "[l]engthy discussion with [claimant] on the importance of compliance with [medications], diet and exercise."
    Claimant testified that prior to his January 13, 1998 appointment with Dr. Bryant, he never received a diagnosis or information from any source, including Dr. Bryant, that he was suffering from hypertension.  Claimant testified he did not understand he was suffering from hypertension until January 1998, when Dr. Bryant allegedly told him that his hypertension was caused by his work at the fire department and that claimant needed to retire. Claimant had been president of his local union.  He worked with the International Association of Firefighters and the Virginia Professional Firefighters developing legislation on presumptive occupational disease claims.  Claimant testified he was aware, prior to January 1998, that he was afforded special workers' compensation coverage for the disease of hypertension. Claimant acknowledged he had known for at least fifteen years that hypertension "is a condition that's covered under the presumption under Workers' [Compensation Act] that you as a firefighter would be entitled to." Claimant testified that if a doctor had diagnosed him with hypertension prior to January 1998, he would have filed his claim earlier.
    Code Sec. 65.2-406(A) states, in part:
The right to compensation under this chapter shall be forever barred unless a claim is filed with the commission within one of the following time periods:
*      *      *      *      *      *      *
5.  For all other occupational diseases [including hypertension], two years after a diagnosis of the disease is first communicated to the employee or within five years from the date of the last injurious exposure in employment, whichever first occurs.
    This filing requirement is jurisdictional.  Hawks v. Henrico County Sch. Bd., 7 Va. App. 398, 401, 374 S.E.2d 695, 696 (1988); Musick v. Codell Constr. Co., 4 Va. App. 471, 473, 358 S.E.2d 739, 740 (1987) (citing Anderson v. Clinchfield Coal Co., 214 Va. 674, 675, 204 S.E.2d 257, 258 (1974)).  "Moreover, the burden is upon the claimant to prove compliance with the statute."  Hawks, 7 Va. App. at 401, 374 S.E.2d at 697.
    "Whether a diagnosis of an occupational disease was communicated and when the communication occurred are factual determinations to be made by the commission upon the evidence.  Upon appellate review, the findings of fact made by the commission will be upheld when supported by credible evidence."  Uninsured Employer's Fund v. Mounts, 24 Va. App. 550, 558, 484 S.E.2d 140, 144 (1997) (citations omitted), aff'd on other grounds, 255 Va. 254, 497 S.E.2d 464 (1998).  See also A. G. Van Metre, Jr., Inc. v. Gandy, 7 Va. App. 207, 215, 372 S.E.2d 198, 203 (1988).
    Credible evidence supports the commission's finding that claimant was diagnosed with hypertension as early as 1995.  See Dan River, Inc. v. Giggetts, 34 Va. App. 297, 302, 541 S.E.2d 294, 296 (2001). Claimant's own testimony proved he knew "hypertension was high blood pressure."  Even if he did not, "a physician is not required to utilize precise medical terminology to communicate the existence of occupational disease in order to trigger the obligation to file a claim."  Hawks, 7 Va. App. at 403, 374 S.E.2d at 697 (finding an employee received communication of the occupational disease interstital fibrosis when a doctor informed the employee that he had "scarring" of the lungs).  Claimant's medical records indicate Dr. Bryant repeatedly diagnosed hypertension, prescribing medications and behavioral changes to bring the condition under control.
    Code Sec. 65.2-406(A)(5) requires communication of two distinct facts:  (1) a diagnosis of the disease; and (2) the disease is an "occupational disease."  Code Sec. 65.2-400 defines an "occupational disease" as "a disease arising out of and in the course of employment, but not an ordinary disease of life to which the general public is exposed outside of the employment."
    A diagnosis of an occupational disease is not completely communicated to an employee until he receives information indicating the disease is "one 'arising out of and in the course of the employment.'"  Garrison v. Prince William County Bd. of Supervisors, 220 Va. 913, 917, 265 S.E.2d 687, 689 (1980) (citing Code Sec. 65.1-46, a previous version of Code Sec. 65.2-400)  (holding the statute of limitations did not bar a claim filed in 1978, where the employee was told he had hypertension in 1975, but he was not told hypertension arose out of and in the course of his employment).  The determinative issue here, therefore, is whether the diagnosis of hypertension  as an "occupational disease" was communicated to claimant prior to October 21, 1997, two years before the filing of his claim.
    No physician communicated to claimant that a nexus existed between his hypertension and his job prior to the appointment with Dr. Bryant in January 1998.   However, this fact does not end our inquiry.  It must be determined when claimant was informed that hypertension is an occupational disease.
    Communication of an occupational disease need not come from a medical doctor.  In Ratliff v. Dominion Coal Co., 3 Va. App. 175, 179, 349 S.E.2d 147, 149 (1986), the Court held a letter from the United States Department of Labor, informing a miner that he was disabled under the Black Lung Benefits Act, constituted "a medical determination of total disability due to pneumoconiosis" and triggered the running of the Virginia statute of limitations for workers' compensation benefits.  The Court rejected Ratliff's argument "that the Department of Labor letter was an administrative or legal determination, but not a 'medical determination.'"  Id.  The Court further explained that Ratliff knew or should have known after receiving the letter that, although the letter referred to federal standards, "it was,
nevertheless, incumbent upon Ratliff to file a Virginia claim" of disability due to pneumoconiosis within three years of receiving the letter.   Id. at 180, 349 S.E.2d at 149-50.
    Alexandria v. Cronin, 20 Va. App. 503, 458 S.E.2d 314 (1995), aff'd, 252 Va. 1, 471 S.E.2d 184 (1996)  is dispositive of this case.  In Cronin, Cronin received a formal diagnosis of coronary heart disease in October 1989 and soon thereafter filed with the city for service-connected disability retirement from his job as a firefighter.  Id. at 505, 458 S.E.2d at 315.  Cronin died on February 22, 1992, and his estate filed a claim for benefits with the commission.  Id. at 506, 458 S.E.2d at 315.  The commission concluded Cronin's estate was not barred by the limitation period because Cronin was "not 'medically advised that his condition was causally related to his work.'"  Id. at 507, 458 S.E.2d at 316 (citing the commission's decision).
    In overturning the commission, the Court held:  By interpreting the statute as requiring proof of a communication by a physician of the employee's occupational disease, the commission ignores the fact that, while many employees may receive a diagnosis of his or her disease from a physician, the claimants may receive the communication that such a disease is a compensable occupational disease from someone other than a physician, often an attorney or someone in charge of personnel or administering benefits.  The commission's ruling overlooks practical experience under the Act and the fact that the compensability of an occupational disease is a creation of the legislature.  A physician's diagnosis of an employee's
condition is not dispositive on the issue of compensability and physicians often reach
different conclusions about a condition's origin.
*      *      *      *      *      *      *
Neither the Court of Appeals nor the Supreme Court of Virginia has interpreted Code Sec. 65.2-406(A)(5) as requiring a communication from a physician to trigger the running of the limitations period.  Code Sec. 65.2-406(A)(5) does not require that an employee receive from a physician a communication that his disease requires that the employee, simultaneously with or sometime after the diagnosis of his condition, learn that the condition is an occupational disease for which compensation may be awarded.  See Ratliff v. Dominion Coal Co., 3 Va. App. 175, 349 S.E.2d 147 (1986). Id. at 508-09, 458 S.E.2d at 316-17.  The Court concluded, "Cronin received a medical diagnosis of his heart condition and acted upon such diagnosis to receive service-connected disability benefits.  This action proved that Cronin was informed for purposes of the statute."  Id. at 510, 458 S.E.2d at 317.
    As in Cronin, claimant here was not informed by a doctor that his hypertension was work-related.   However, claimant had known for ten to fifteen years that hypertension is an occupational disease which is presumptively compensable under Code Sec. 65.2-402(B).  He had lobbied for legislation to enact that presumption.  He was aware, prior to his diagnosis, that his work as a firefighter afforded him special workers' compensation coverage for hypertension.  Most significantly, claimant testified that if a doctor had diagnosed him with hypertension prior to January 1998, he would have filed his claim earlier, suggesting he knew such a diagnosis was an occupational disease.  This testimony also belies claimant's contention that he only had a "general knowledge" of the compensability of hypertension.  Overall, claimant's testimony actually underscored the fact that he did know hypertension was a presumptively compensable occupational disease.
    As in Cronin, claimant "receive[d] the communication that such a disease is a compensable occupational disease from someone other than a physician."  20 Va. App. at 508, 458 S.E.2d at 316.  He had this knowledge when the diagnosis was communicated to him, as he had known hypertension was an occupational disease for at least fifteen years prior to the diagnosis. 
    The evidence supports the commission's findings that a diagnosis of an occupational disease was communicated to claimant as of January 1995.  Therefore, his October 1999 filing falls far outside the two-year statute of limitations set forth in Code Sec. 65.2-406(A)(5).  The source of the communication of occupational disease is immaterial as long as claimant learned "that the condition is an occupational disease for which compensation may be awarded.Id. at 509, 458 S.E.2d at 317.  Kenneth R. Owens v. York Co. Fire & Rescue, Record No. 1898-01-4 (May 28, 2002). WP Version.

The commission did not err in denying claimant's October 7, 1997 claim for benefits under Code Sec. 65.2-402(A), but did err in denying his June 7, 2000 claim for benefits under Code Sec. 65.2-402(A). On October 30, 1995, Dr. Thomas L. Munzel diagnosed claimant, who had worked as a firefighter with the James City County Fire Department since June of 1976, as having "virtually reversible obstruction," which, according to Dr. Munzel, was essentially a mild asthma variant of "adult onset reversible obstructive airways disease." Claimant received treatment from Dr. Munzel for his asthma from 1995 to 1999 but did not miss work or have any work restrictions imposed on him during that period.  However, in early 2000, after working at a fire in December of 1999, claimant's progressively worsening lung condition became disabling.  On February 7, 2000, Dr. Munzel, having diagnosed claimant's pulmonary condition as irreversible chronic obstructive pulmonary disease and acute exacerbation of his asthma, directed that claimant not return to work as an active firefighter for at least two months.  Dr. Munzel explained that claimant was disabled from working as an active firefighter at the time "due to his asthma," which was "clearly exacerbated by the fire fighting."  From that point on, claimant never returned to work in an unrestricted capacity.  In December of 2000,  Dr. Munzel testified claimant had "continued to be disabled due to his asthma" and would never be able to actively fight fires again.
    Based on the first diagnosis, claimant filed a claim for benefits with the commission on November 14, 1995, for "virtually reversible obstruction" disease with a date of communication of October 30, 1995.  Although he sought no specific benefits, claimant filed the claim to "have [it] on the record for [the] future."  Claimant withdrew the claim on May 2, 1996, but timely refiled it on October 7, 1997.  In refiling the claim, claimant specifically indicated he had "not missed any work at [that] time."  Rather, he simply wanted to have his claim "on [the] record for [the] future."  On June 7, 2000, claimant notified the commission that he sought payment of his medical bills related to the virtually reversible obstructive disease communicated to him by Dr. Munzel on October 30, 1995. On June 7, 2000, claimant filed a second claim for benefits alleging "Chronic obstructive pulmonary disease (COPD)/small airways disease/asthma" with a date of communication of February 7, 2000.  In filing that claim, claimant sought disability and medical benefits for the period beginning February 7, 2000.
    Code Sec. 65.2-406(A)(5) provides that the right to compensation for occupational diseases shall be forever barred unless a claim is filed within two years after a diagnosis of the disease is first communicated to the employee.  Hence, "once an employee receives a communication of an occupational disease, it is incumbent upon him to file a claim" within two years of that communication. Parris v. Appalachian Power Co., 2 Va. App. 219, 225-26, 343 S.E.2d 455, 458-59 (1986) (footnote omitted).  "[I]f an employee receives a communication of a diagnosis of an occupational disease, and does not act on that communication prior to the
running of the statute of limitations, then he is barred from filing a later claim based on a later diagnosis."  Id. at 225, 343 S.E.2d at 458 (citing Anderson v. Clinchfield Coal Co., 214 Va. 674, 675, 204 S.E.2d 257, 258 (1974)).  "Once a claim is filed, it is the duty of the Commission to determine: (1) whether the disease is in fact an 'occupational disease' as defined in Code Sec. 65.1-46 [now Code Sec. 65.2-400], and if so, (2) whether that occupational disease is compensable."  Id. at 226, 343 S.E.2d at 459 (footnote omitted).
    In this case, claimant acted appropriately upon receiving a communication of a possible occupational disease from Dr. Munzel.  Once Dr. Munzel diagnosed him with virtually reversible obstruction on October 30, 1995, claimant, after withdrawing an earlier claim, filed a timely claim for virtually reversible obstruction with the commission on October 7, 1997.  Hence, it then became the commission's duty to determine whether
the claimant's disease was an occupational disease, and if so, whether that occupational disease was compensable.  Code Sec. 65.2-402(A) provides, in pertinent part: Respiratory diseases that cause . . . any health condition or impairment of [volunteer or salaried] firefighters . . . resulting in total or partial disability shall be presumed to be occupational diseases, suffered in the line of duty, that are covered by this title unless such presumption is overcome by a preponderance of competent evidence to the contrary. Thus, in order to establish the relevant prima facie case necessary to secure the benefit of the presumption in Code Sec. 65.2-402(A), a claimant must prove his occupation as a firefighter and his disability from a respiratory disease.  See
City of Norfolk v. Lillard, 15 Va. App. 424, 427, 424 S.E.2d 243, 245 (1992).  "Disability from a disease has been defined as the stage when the disease prevents the employee from performing his work efficiently."  Salyer v. Clinchfield Coal Corp., 191 Va. 331, 338, 61 S.E.2d 16, 20 (1950). Here, claimant failed to establish that the respiratory disease referenced in his October 7, 1997 claim rendered him totally or partially disabled.  Accordingly, the deputy commissioner and the commission did not err in holding the presumption in Code Sec. 65.2-402 had no application to claimant's October 7, 1997 claim and in concluding claimant failed to prove that virtually reversible obstruction was a compensable occupational disease.
   
However, claimant filed a claim for benefits on June 7, 2000, for "Chronic obstructive pulmonary disease (COPD)/small airways disease/asthma," with a date of communication of February 7, 2000.  In that claim, claimant sought disability benefits commencing February 7, 2000. The commission ruled that claimant's June 7, 2000 claim was not a separate claim and that the claimant sought "disability benefits beyond the running of the statute of limitations for his lung condition, which [was] not compensable."
    In Parris v. Appalachian Power Co., 2 Va. App. 219, 226, 343 S.E.2d 455, 459 (1986) after examining four prior cases involving multiple diagnoses of the "same" occupational disease, the Court of Appeals set out the "rule of law" discerned from those cases, stating as follows: "If the Commission determines that the claimant does not have an occupational disease, or that his occupational disease is not compensable, then the statute of limitations in regard to the first communication of the diagnosis forming the basis of that claim has no bearing on a subsequent diagnosis and a claim filed as a result of the communication of that diagnosis." See Cook v. Clinchfield Coal Co., 215 Va. 599, 212 S.E.2d 263 (1975). Here, claimant, after failing to prove he had a compensable occupational disease based on his first diagnosis and claim, received a second diagnosis and filed a timely second claim pertaining to the same condition, which had since worsened and become compensable.  Thus, applying the same rationale set forth in Parris to the instant case, we conclude the commission erred in denying and dismissing claimant's June 7, 2000 claim and, in light of employer's stipulation that it could not overcome the presumption in Code Sec. 65.2-402 as to that claim, in holding that the disease upon which the June 7, 2000 claim was based was not compensable.  It matters not, under Cook and Parris, that claimant's June 7, 2000 claim was based, as the commission found, upon the same condition upon which claimant's initial, denied claim was based.  Once the commission determined that claimant had failed to prove he had a compensable occupational disease, with respect to his first claim, the claimant was not barred from receiving an award on his June 7, 2000 claim based on the diagnosis communicated to him on February 7, 2000.  Melvin H.
