MI HB4764

Expands the definition of "personal injury" for workers' compensation to include full-time, part-time, and on-call county medical examiners, deputy county medical examiners, and medical examiner investigators, covering respiratory and heart diseases that develop during active service

Allows county medical examiners, deputy medical examiners, and medical examiner investigators with 60 or more months of active service to claim benefits from the Christopher R. Slezak first responder presumed coverage fund for certain cancers, effective January 1, 2026

Covered cancers for medical examiner personnel include respiratory tract, bladder, skin, brain, kidney, blood, thyroid, testicular, prostate, lymphatic, ovarian, breast, and non-HPV cervical cancer

Creates a rebuttable presumption that covered cancers arose from employment, which can only be overcome by scientific evidence of substantial tobacco use within 10 years prior to injury that significantly contributed to the cancer

Requires medical examiner claimants to first apply for pension benefits before filing for workers' compensation benefits under this provision
