OPINION
This аppeal involves a workmen’s compensation claimant who, after receiving benefits under the Nevada Occupational Diseases Act (NRS chapter 617) for nearly six years, asserted thаt he was entitled to additional benefits under the Nevada Industrial Insurance Act (NRS chapter 616). We hold thаt the claim was properly classified as one for occupational disease benefits under NRS chapter 617 and that, therefore, the district court erred in ordering payment of additional bеnefits under NRS chapter 616.
*337 On August 3, 1978, Conner, an officer with the Las Vegas Metropolitan Police Department, was assaulted while subduing a suspect. Twenty to thirty minutes later he experienced chest pains, and was diagnosed as having suffered a myocardial infarction. A workmen’s compensation claim wаs filed, and Conner was notified on August 30, 1978, that occupational disease benefits would be awarded. In 1979, Conner underwent a quadruple coronary bypass operation. The surgery was successful, and Conner returned to work with the Las Vegas Metropolitan Police Department. In May of 1984, Conner was instructеd to report for a disability rating examination. SIIS Medical Advisor, Dr. Joseph George, concluded thаt Conner’s heart disorder justified a 12 percent permanent partial disability (PPD) rating. However, Conner was notified shortly after the examination that no PPD award would be made, since PPD benefits were not available for occupational disease claims prior to January 1, 1980. See 1979 Nev. Stats. ch. 533, § 56.5, at 1063. Since Conner’s heart attack occurred in 1978, the SIIS determined that Conner was not entitled to PPD benefits. Conner аppealed this determination, and both the hearings officer and the appeals officer affirmed the denial of additional benefits. However, the district court reversed, holding that Conner’s claim should be classified as an industrial injury, and therefore that PPD benefits should be awarded under NRS chapter 616.
NRS 616.110(2) provides that, “[f]or the purposes of this chapter, coronary thrombosis, coronary occlusion, or any other ailment or disorder of the heart, and any death or disability ensuing therefrom shall not be deemed to be an injury by accident sustained arising out of and in the course of the employment.” In contrast, NRS 617.457(1) provides that, as to police officers, “diseases of the heart, resulting in either temporary or permanent disability or death, are occupational diseases and comрensable as such under the provisions of this chapter if caused by extreme overexertion in times of stress or danger. . . .” A reading of these two statutes compels the conclusion that the legislature intended Conner’s condition to be compensated under chapter 617 rather than chaptеr 616. Since entitlement to benefits is determined as of the date of injury (NRS 617.240; 616.625), the fact that PPD benefits were not authorized for occupational disease claims in 1978 precludes an award of such benefits to Conner.
Conner’s assertion that a different result is mandated by this court’s ruling in SIIS v. Buckley,
In the present сase, both the SIIS medical advisor and Conner’s own physician testified that Conner had a preexisting coronary disease which was aggravated by the assault. This case is clearly controlled by Spencer, which precludes an award of benefits under chapter 616.
While we are sympathetic to the cause of a dedicated police officer who sufferеd a heart attack arising in the line of duty, we are unable to increase the workmen’s compensation benefits recoverable beyond the limits set by the legislature. As stated in
Spencer,
“We are not empоwered ... to go beyond the face of the statute to lend it a construction contrary to its clear meaning. . . . Nor is it within our province to question the wisdom of this statute, although we may be sympathetic tо appellant’s claim.”
In light of the above, it is unnecessary to determine whether there was substantial evidence to support thе appeals officer’s determination that Conner did not file a timely claim under chapter 616.
Accordingly, the order of the district court is reversed, and the decision and order of the appeals officer is reinstated.
