TennCare - As introduced, directs the bureau to establish a temporary TennCare benefits program to provide medical assistance on a temporary basis to certain individuals who do not qualify for enrollment in TennCare, CoverKids, or a successor program; requires the bureau to submit a waiver to the federal centers for medicare and medicaid services by December 31, 2025. - Amends TCA Title 71, Chapter 5.

HB 18 proposes a temporary health coverage program for Tennesseans who don't qualify for existing TennCare or CoverKids. It would provide up to 60 months of medical assistance (resetting at age 21) to individuals under 21 with income ≤138% of the federal poverty level, or adults ≥21 with similar income, subject to strict 12-month/24-month usage limits. The program requires a federal waiver by December 2025, uses 90% federal/10% state funding, and explicitly states it does not replace eligibility for regular programs (benefits pause if enrollment becomes possible). The bill failed in the Insurance Committee on March 5, 2025, and remains inactive.
