Relating to health benefit plan coverage for certain treatments prescribed for autism spectrum disorder.

SB 1678 requires health benefit plans in Texas to cover specific autism-related treatments prescribed for autism spectrum disorder. The bill adds applied behavior analysis, speech therapy, occupational therapy, physical therapy, behavior management, developmental interventions, and medications or supplements used to address autism symptoms to the list of "generally recognized services" covered under insurance. This applies to health plans delivered, issued, or renewed on or after January 1, 2026, affecting both insurers and individuals seeking these treatments. The law takes effect September 1, 2025, with existing plans before that date governed by prior law.
