Medicaid; expand eligibility under federal Affordable Care Act and under CHIP.

HB 55 would expand Mississippi's Medicaid program to cover two groups: (1) adults under 65 who aren't pregnant, don't qualify for Medicare, and earn up to 133% of the federal poverty level (about $20,000 annually for an individual), and (2) children under 19 whose families earn between 133% and 200% of the federal poverty level (about $30,000 annually for a family of three). The bill replaces Mississippi's existing Children's Health Insurance Program (CHIP) with federal standards under the Affordable Care Act, repealing seven previous state CHIP statutes. It directly affects low-income Mississippi residents who currently fall outside Medicaid eligibility due to income thresholds. The proposed changes would align Mississippi's coverage with federal Medicaid expansion guidelines.
