Medicaid; require Governor and Division of Medicaid to negotiate to obtain federal waiver to expand Medicaid coverage.

HB 546 requires Mississippi's Governor and Division of Medicaid to negotiate a federal waiver to expand Medicaid coverage. If approved, it would extend coverage to low-income adults aged 19-64 with incomes up to 138% of the federal poverty level (FPL), including parents earning 22-138% FPL. Key provisions include offering at least two private insurance options, capping cost-sharing at 2-5% of income, and creating "Mississippi Healthy Living Accounts" for enrollees earning 50-138% FPL to cover copays. The bill mandates that the state update its Medicaid plan to implement the waiver-approved expansion after CMS approval.
