Medicaid Program Improvement Act

The Medicaid Program Improvement Act requires states to regularly verify and update the addresses of Medicaid and CHIP (Children's Health Insurance Program) enrollees using reliable data sources, starting January 1, 2026. States must act on any address changes obtained through these sources, ensuring records remain accurate. Managed care organizations contracting with states must also transmit address information they receive directly from enrollees to the state. This applies to all 50 states and the District of Columbia, aiming to improve data accuracy for program administration.
