HB 1988 would expand Oklahoma Medicaid eligibility to cover adults aged 19 to 64 with incomes up to 160% of the federal poverty level. This change directly affects low-income working adults and families who currently fall outside Medicaid coverage under existing rules. The bill requires the Oklahoma Health Care Authority to implement this expanded eligibility starting November 1, 2025. It creates a specific income threshold for coverage without altering other Medicaid program rules.
