Enrollment and Spending for Medicare-Medicaid Enrollees

This data collection draws on Medicare and Medicaid administrative data to present national and state-level information on people who are covered by both Medicare and Medicaid, referred to as Medicare-Medicaid enrollees (also known as dually-enrolled beneficiaries). Medicare-Medicaid enrollees qualify for Medicare coverage on the basis of age (65 and older) or disability. To qualify for Medicaid benefits, Medicare beneficiaries must meet eligibility criteria based on financial (related to income and wealth) and non-financial (generally, age or disability) requirements. For “partial benefit” enrollees, Medicaid pays Medicare premiums and, in many cases, also pays Medicare’s deductibles and cost-sharing on behalf of Medicare-Medicaid enrollees. Medicare-Medicaid enrollees who also receive the full range of Medicaid benefits that are not covered by Medicare are generally referred to as “full benefit” enrollees. This data collection includes the number of Medicare-Medicaid enrollees and Medicare and Medicaid spending on these enrollees.
