Amends TCA Title 8; Title 56 and Title 71.

Tennessee SB1426, also known as "Lucca's Law," amends provisions related to health insurance coverage for pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) and pediatric acute-onset neuropsychiatric syndrome (PANS). The bill authorizes managed care organizations (MCOs) to provide coverage for medically necessary treatments prescribed by physicians, including antibiotics and behavioral therapies, effective January 1, 2026. Key changes include the removal of mandatory adherence to best practice standards for treatment and the elimination of lifetime or policy duration limits on coverage for these conditions.
