Relating to group health benefit plan coverage for early treatment of first episode psychosis.

HB 1594 requires Texas group health benefit plans to cover early treatment for first episode psychosis for individuals under 26 years old. The bill defines "first episode psychosis" as the initial onset of psychosis symptoms caused by medical conditions, serious mental illness, or substance use. It mandates coverage for specific services including coordinated specialty care (such as psychotherapy and medication management), assertive community treatment, and peer support services like recovery mentoring. Coverage must be provided based on medical necessity and through a bundled payment model for treatment providers.
