WA HB2405

Establishes a pilot program through the Department of Labor & Industries to expand access to evidence-based treatment for workers with work-related posttraumatic stress disorder (PTSD), particularly those in high-risk occupations with repetitive trauma exposure.

Authorizes PTSD treatment before claim adjudication, including a diagnostic evaluation and up to 11 treatment sessions within 90 days of diagnosis, with costs for rejected state fund claims spread across risk classes with PTSD presumption coverage.

Allows up to six additional treatment sessions within one year of claim closure when necessary to maintain the worker's level of functioning.

Permits the department to fund grants for workplace behavioral health programs including suicide prevention, mental health training, and supportive workplace culture development using return-to-work project funds.

Requires the director to report recommendations to the legislature by July 1, 2030, on whether to extend or expand the pilot program, with the pilot expiring December 31, 2030.
