AZ HB2506

Creates presumption that certain cancers (brain, bladder, rectal, colon, lymphoma, leukemia, adenocarcinoma, mesothelioma of respiratory tract, and others) diagnosed in firefighters and fire investigators are occupational diseases arising from employment if they passed pre-employment physical, worked hazardous duty for 5+ years, and meet other conditions.

Allows workers' compensation insurers covering firefighters and fire investigators to file one additional uniform percentage rate deviation (beyond the standard six allowed) to address anticipated increased losses from cancer-related claims under the new presumption.

Requires rate deviation filings for firefighter/fire investigator cancer coverage to be supported by actuarial analysis including anticipated loss ratios, claim frequency and severity, and may be based on data from various sources including the Industrial Commission of Arizona.

Mandates all insurance carriers, self-insuring employers, and workers' compensation pools report cancer-related claim information (cancer type, costs, reserves) to the Industrial Commission of Arizona, which must compile and share this data with insurers and rating organizations to assist with rate-setting.

Presumption applies to firefighters and fire investigators currently in service or former employees age 65 or younger diagnosed within 15 years of employment; presumption may be rebutted by clear and convincing evidence of a specific non-occupational cause.
