Cal. Lab. Code § 3212.5
In the case of a member of a police department of a city or municipality, or a member of the State Highway Patrol, when any such member is employed upon a regular, full-time salary, and in the case of a sheriff or deputy sheriff, or an inspector or investigator in a district attorney's office of any county, employed upon a regular, full-time salary, the term "injury" as used in this division includes heart trouble and pneumonia which develops or manifests itself during a period while such member, sheriff, or deputy sheriff, inspector or investigator is in the service of the police department, the State Highway Patrol, the sheriff's office or the district attorney's office, as the case may be. The compensation which is awarded for such heart trouble or pneumonia shall include full hospital, surgical, medical treatment, disability indemnity, and death benefits as provided by the provisions of this division.
Such heart trouble or pneumonia so developing or manifesting itself shall be presumed to arise out of and in the course of the employment; provided, however, that the member of the police department, State Highway Patrol, the sheriff or deputy sheriff, or an inspector or investigator in a district attorney's office of any county shall have served five years or more in such capacity before the presumption shall arise as to the compensability of heart trouble so developing or manifesting itself. This presumption is disputable and may be controverted by other evidence, but unless so controverted, the appeals board is bound to find in accordance with it. This presumption shall be extended to a member following termination of service for a period of three calendar months for each full year of the requisite service, but not to exceed 60 months in any circumstance, commencing with the last date actually worked in the specified capacity.
Such heart trouble or pneumonia so developing or manifesting itself in such cases shall in no case be attributed to any disease existing prior to such development or manifestation.
The term "members" as used herein shall be limited to those employees of police departments, the California Highway Patrol and sheriffs' departments and inspectors and investigators of a district attorney's office who are defined as peace officers in Section 830.1, 830.2, or 830.3 of the Penal Code.
