Medicaid; expand eligibility under federal Affordable Care Act.

HB 427 would expand Mississippi Medicaid eligibility to include non-pregnant adults under age 65 with incomes up to 133% of the federal poverty level (FPL), who currently do not qualify for coverage under existing rules. This directly affects low-income working adults in Mississippi who earn too much for current Medicaid but fall below the ACA's income threshold for coverage. The bill amends Section 43-13-115 to add this new eligibility category, excluding pregnant individuals and those enrolled in Medicare. It aligns Mississippi's Medicaid program with the federal Affordable Care Act's expansion, enabling thousands of uninsured adults to gain health coverage without requiring new state funding.
