Workers Compensation - As enacted, creates a presumption that the diagnosis of a law enforcement officer or emergency medical responder with post-traumatic stress disorder as the result of responding to certain incidents was incurred in the line of duty for purposes of workers' compensation coverage. - Amends TCA Title 7, Chapter 51 and Title 50, Chapter 6.

HB 310 creates a legal presumption that post-traumatic stress disorder (PTSD) diagnosed in law enforcement officers or emergency medical responders (like EMTs and paramedics) was incurred while performing job duties, making it automatically eligible for workers' compensation coverage. This applies to those diagnosed after responding to specific incidents, shifting the burden to employers to prove otherwise. The bill amends Tennessee workers' compensation laws (TCA Title 7, Chapter 51 and Title 50, Chapter 6) to explicitly include these professions under the presumption, removing prior exclusions of "firefighter" language. It directly affects first responders who develop PTSD in the line of duty, streamlining their access to benefits starting July 1, 2025.
