Relating to the eligibility of certain first responders for workers' compensation benefits for post-traumatic stress disorder.

HB 673 would expand Texas workers' compensation coverage to include post-traumatic stress disorder (PTSD) for specific first responders. It defines eligible individuals as police officers, emergency medical personnel (EMTs/paramedics), and firefighters certified under Texas law. The bill requires that PTSD be diagnosed as caused by work-related events, with medical evidence showing the condition was likely work-related, and sets the injury date as when the responder first suspected the connection to their job. This change updates existing workers' comp rules to explicitly cover PTSD for these professions, without creating new benefits or funding.
