This 2007 decision by the Nevada Supreme Court clarifies that firefighters are presumptively entitled to occupational disease benefits as long as their disablement occurs at least five (5) years after full-time, uninterrupted work. Under Nevada firefighters workers’ compensation law NRS 617.457, it makes no difference if firefighters acquired the original medical condition or injury less than five years after working; instead, all that matters is the date of being disabled from the condition.
In the instant case, a firefighter was diagnosed with heart problems only three years after beginning what became a 25-year-long career. After retiring, his workers’ comp claim for occupational disease benefits was denied because he developed his heart condition less than five years after working as a firefighter. But the Nevada Supreme Court claimed that the workers’ comp administrators misinterpreted the statute, and that the only relevant date is when the worker became disabled, not when he/she originally developed a medical condition. Since the firefighter in this case had worked for well over five years before claiming he was disabled, he is presumptively entitled to benefits. (Then the court remanded the case so administrators can determine whether the firefighter is indeed disabled.)
This appeal involves, in part, determining the scope of NRS 617.457(1), which sets forth a conclusive presumption that entitles firefighters with heart disease to occupational disease benefits from the date of disablement, so long as the date of disablement occurs at least five years after full-time, uninterrupted work as a firefighter. During the administrative proceedings below, an appeals officer upheld the denial of a firefighter’s occupational disease claim under NRS 617.457(1), concluding that the firefighter was not entitled to that statute’s conclusive presumption because his heart disease predated the completion of five years’ qualifying employment, and his preexisting heart condition had merely progressed over many years, irrespective of his work as a firefighter. The district court later denied judicial review.
We conclude, however, that the statutory conclusive presumption applies to a claimant who contracts heart disease before completing the five-year vesting period, but whose date of disablement from the heart disease takes place after the five-year period has concluded. Accordingly, we reverse the district court’s order denying judicial review of the appeals officer’s decision. Since, however, the appeals officer did not determine whether the firefighter is actually disabled and therefore entitled to benefits, we remand this matter for further administrative proceedings.
Appellant Buddy Manwill was employed as a firefighter by the Clark County Fire Department from 1981 to 2006. During his 1991 annual physical examination, Manwill revealed that, when he was twenty-four-years old (around 1984), he was diagnosed as having had pericarditis (inflammation of the fibrous tissue that surrounds the heart). Nevertheless, he was cleared for full duty then and in subsequent years.
Starting in 1996, Manwill’s chest x-rays and electrocardiograms revealed abnormal findings. A physician suggested that Manwill might have hypertensive disease or congenital heart disease and recommended further evaluation. During the following years, Manwill continued to have abnormal test results and underwent several cardiac evaluations, which ultimately revealed calcification of his pericardium. While some light-duty job restrictions were intermittently imposed, Manwill was otherwise cleared for full-duty firefighter work.
In autumn 2005, magnetic resonance imaging showed constrictive pericarditis, and a physician recommended that Manwill undergo diagnostic catheterization and consideration for a pericardiectomy. Meanwhile, however, Manwill was released for full duty.
Shortly thereafter, Manwill filed an occupational disease claim for constrictive pericarditis, but his claim was summarily denied in a letter pointing only to NRS 617.457(1), the firefighters’ conclusive presumption statute. Under that statute, as noted above, the heart disease of a claimant who has been continuously employed as a full-time firefighter for five or more years “before the date of disablement [is] conclusively presumed” to be work-related.
Manwill administratively appealed the claim denial, and an appeals officer determined that, even though Manwill qualified for the conclusive presumption as a full-time firefighter employed with respondent Clark County for more than five years, the conclusive presumption statute did not apply to his claim because Manwill’s heart condition, first diagnosed in 1984, predated the completion of his five years’ employment vesting period in 1986 and, as medically expected regardless of employment, simply worsened over time. In other words, the appeals officer determined that “[w]hile the presumption of NRS 617.457 relieves a firefighter from having to demonstrate the extent to which his occupation may have contributed to his heart disease, [Manwill’s] occupation as a firefighter is not a contributing factor to the progression of his pericarditis and therefore the presumption does not apply”-“[a] congenital heart condition does not become an occupational disease based upon a firefighter[‘]s qualification for coverage under NRS 617.457.”2 After the district court denied judicial review, Manwill appealed.
Like the district court, this court reviews an appeals officer’s decision for clear error or arbitrary abuse of discretion.3The appeals officer’s fact-based conclusions of law are entitled to deference, and they will not be disturbed if supported by substantial evidence.4 Further, we may not substitute our judgment for that of the appeals officer as to the weight of the evidence on a question of fact,5 and our review is limited to the record before the appeals officer.6Nonetheless, we independently review the appeals officer’s purely legal determinations, including those of statutory construction.7 Here, based on our independent review of NRS 617.457(1), we conclude that the appeals officer clearly erred in construing that statute as requiring a claimant to demonstrate that his employment as a firefighter contributed to his heart disease, when that heart disease predated completion of the claimant’s five-year statutory vesting period, even if any date of disablement occurred long after the five-year period had passed.
In Nevada, a person seeking compensation for an occupational disease usually must establish, by a preponderance of the evidence, that the disease arose out of and in the course of employment.8 As noted above, however, NRS 617.457(1) waives this requirement for claimants who are disabled by heart disease after having continuously worked as full-time firefighters for five or more years, by conclusively presuming that the heart disease is a sufficiently work-related occupational disease:
Notwithstanding any other provision of this chapter, diseases of the heart of a person who, for 5 years or more, has been employed in a full-time continuous, uninterrupted and salaried occupation as a firefighter or police officer in this State before the date of disablement are conclusively presumed to have arisen out of and in the course of the employment.9
Under its plain language, this provision requires a firefighter seeking occupational disease benefits to show only two things: heart disease and five years’ qualifying employment before disablement.10 Thus, NRS 617.457(1) relieves a qualifying firefighter not merely “from having to demonstrate the extent to which his occupation may have contributed to his heart disease,” as the appeals officer concluded, but also from having to demonstrate that his occupation contributed to his heart disease altogether.11 As a result, once the firefighter shows that he has heart disease and five years’ qualifying employment before the date of disablement, his heart disease, whatever the cause-whether congenital, idiopathic, or otherwise induced-is covered, despite any preexisting symptom or condition.12 Consequently, the conclusive presumption under NRS 617.457(1) applies even when a claimant’s “occupation as a firefighter is not a contributing factor to the progression of [the disease]”; that is, any heart disease of a firefighter is deemed occupational, whenever contracted, so long as the firefighter qualifies for benefits under the terms of this statute.13
To qualify for NRS 617.457’s conclusive presumption, a firefighter must have worked in a full-time, continuous, uninterrupted, and salaried firefighter position for five or more years before the date of disablement.14 In this case, as the appeals officer found and the parties do not dispute, Manwill worked in a qualifying firefighter position for significantly more than five years before the date of his occupational disease claim. Accordingly, even if his heart disease was apparent before he had completed five years’ employment as a firefighter, so long as his date of disablement occurred after the five-year statutory vesting period ran, he was entitled to NRS 617.457’s conclusive presumption that his heart disease arose out of and in the course of employment.15 The appeals officer plainly erred in concluding otherwise.16
In denying the claim under NRS 617.457, the appeals officer did not determine whether, and if so when, Manwill was disabled from his heart disease. As we most recently reiterated in Employers Insurance Co. of Nevada v. Daniels,17 to receive occupational disease compensation, a firefighter must be disabled by the heart disease: “[a]n employee is not entitled to compensation ‘from the mere contraction of an occupational disease. Instead, compensation ․ flows from a disablement resulting from such a disease.’ ” 18 Because, here, the appeals officer did not determine whether Manwill was disabled from his heart disease for purposes of obtaining compensation, we remand this matter for further proceedings with respect to Manwill’s occupational disease claim.
NRS 617.457(l )’s conclusive presumption applies to heart diseases of qualifying firefighters, entitling them to occupational disease compensation from the date they are deemed disabled, so long as this date occurs after at least five years of full-time, continuous work as a firefighter. Any onset of the heart disease before the five-year vesting period is completed does not affect the statutory presumption. Because the appeals officer plainly erred in concluding that the conclusive presumption statute did not apply to Manwill’s claim because Manwill had developed heart disease before he completed five qualifying years as a firefighter, we reverse the district court’s order denying judicial review, and we remand this matter to the district court. On remand, the district court is instructed to grant judicial review and remand this matter for additional administrative proceedings to determine whether Manwill is entitled to occupational disease compensation in light of this opinion and NRS 617.457.
- We have determined, under NRAP 34(f)(1), that oral argument is not warranted in this case.
- It is unclear from the order whether, and if so based on what information, the appeals officer determined that Manwill’s heart disease was congenital. According to the physician reports noted in the order, various historical aspects of Manwill’s heart condition were “suggestive of hypertensive disease or congenital heart disease” and “most likely secondary to acute trauma, but the true etiology [could not] be determined at [that] time.” With respect to constrictive pericarditis, the noted report indicated that pericarditis can be related to infection, but in other cases, “the cause is unknown,” and thus, it is “difficult to state whether the heart disease is an occupational heart disease.”
