Advancing Enrollment and Reducing Drug Costs Act of 2023

This bill automatically extends Medicare Part D drug coverage subsidies to low-income Medicaid beneficiaries who turn 65. Specifically, it changes eligibility rules so that individuals enrolled in Medicaid under certain state plans (as defined in Section 1902(a)(10)(A)) with income below 200% of the poverty line will be treated as subsidy-eligible for Medicare Part D when they reach age 65. This eliminates the need for separate applications during the transition to Medicare. The change applies to Medicare Part D plan years starting January 1, 2024, directly affecting Medicaid beneficiaries who meet these income and enrollment criteria.
