This legislation amends Title XIX of the Social Security Act to enhance the integrity of Medicaid enrollment by requiring states to regularly verify beneficiary eligibility. Beginning January 1, 2027, all 50 states and the District of Columbia must conduct a quarterly review of the Death Master File to determine if any enrolled individuals are deceased. This proactive measure aims to prevent improper payments and ensure that medical assistance is provided only to eligible, living beneficiaries. If a state identifies an individual as deceased through this process, it must treat the Death Master File information as factual confirmation, disenroll the individual from Medicaid, and discontinue all related payments for medical assistance. However, the bill also includes a crucial safeguard: if an individual is erroneously disenrolled due to misidentification, the state is required to immediately re-enroll them, with coverage reinstated retroactively to the date of disenrollment.
