TX HB331

Expands workers' compensation presumption for firefighters, peace officers, and EMTs who suffer acute myocardial infarction (heart attack) or stroke resulting in disability or death to be considered work-related

Removes the requirement that physical activity be "nonroutine" - now any stressful or strenuous physical activity during emergency response or training qualifies for the presumption

Extends the coverage window from events occurring only while on duty to events occurring up to 8 hours after the end of a shift involving qualifying activities

Adds "law enforcement" explicitly to the list of qualifying emergency response activities alongside fire suppression, rescue, hazardous material response, and emergency medical services

Takes effect immediately with two-thirds legislative vote, otherwise September 1, 2025; applies only to claims filed on or after the effective date
