TennCare - As introduced, requires, on and after July 1, 2026, a minor who is enrolled in TennCare medicaid or the CoverKids program to remain eligible for such program until the minor reaches 18; prohibits the division of TennCare from subjecting the minor to a redetermination of eligibility or disenrollment, except under certain circumstances; requires the director of TennCare to submit any necessary federal waiver request by December 31, 2025. - Amends TCA Title 71.

SB 401 ensures minors enrolled in Tennessee's TennCare Medicaid or CoverKids program remain eligible until age 18, starting July 1, 2026, without requiring rechecks of their eligibility. The bill prohibits the TennCare division from removing minors from coverage except in specific cases like parental request, death, moving out of state, income exceeding limits, or enrollment fraud. The TennCare director must submit a federal waiver request by December 31, 2025, to implement this change. This directly affects minors under 18 currently covered by these programs, guaranteeing continuous healthcare access through age 18.
