HB 1393 requires Tennessee's governor to apply for a federal waiver within 180 days of the bill's effective date to expand TennCare coverage to low-income residents earning up to 138% of the federal poverty level. This would directly affect Tennesseans currently ineligible for Medicaid under existing income limits, potentially providing medical assistance to thousands. The bill amends state law to mandate this waiver application process, with coverage taking effect immediately upon federal approval. The legislation focuses on procedural changes to access federal Medicaid funding, not on altering current eligibility rules.
