HB 2414 expands workers' compensation benefits for first responders diagnosed with post-traumatic stress disorder (PTSD). The bill establishes a presumption that PTSD is a compensable injury if it stems from events occurring in the course of employment, unless proven otherwise. It applies to peace officers, firefighters, and emergency medical personnel employed by the state, local governments, or institutions of higher education. The bill also updates provisions on insurance carrier investigations, requiring faster claims processing and protecting employees from delays in medical benefits.
