HB 1988 expands Oklahoma's Medicaid program to cover adults aged 19 to 64 with household incomes at or below 160% of the federal poverty level. This change directly affects low-income working adults and families who previously did not qualify for Medicaid under Oklahoma's current eligibility rules. The Oklahoma Health Care Authority must implement this expanded coverage starting November 1, 2025. The bill modifies eligibility criteria to include this income group without altering existing Medicaid benefits or funding mechanisms.
