Amends TCA Title 4; Title 8; Title 33; Title 39; Title 49; Title 53; Title 56; Title 63; Title 68 and Title 71.

Tennessee HB1291 amends various sections of the Tennessee Code Annotated to revise requirements for health benefit plans regarding coverage for mental health, alcoholism, and drug dependency services. The bill removes the exemption that allowed plans to avoid coverage if costs increased by more than 1%, ensuring that mental health treatment remains on par with coverage for substance use disorders. Additionally, it expands the definition of health benefit plans to include coverage under TennCare or a successor program and modifies reporting requirements related to parity in coverage and reimbursement rates for these services.
