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

HB 1667 expands workers' compensation coverage in Texas to include post-traumatic stress disorder (PTSD) for specific first responders. It defines "first responders" as peace officers, emergency medical personnel (EMTs/paramedics), and certified firefighters whose primary duties involve life-saving work. The bill requires that PTSD claims be based on a diagnosis linking the condition to employment-related traumatic events, not personnel actions like transfers or terminations. This policy change applies only to claims filed after the bill's effective date, creating a new pathway for affected workers to seek benefits under the state's workers' compensation system.
