Dually eligible for Medicare and Medicaid: two for one or double jeopardy?

This issue brief describes the characteristics of the population of individuals known as "dual eligibles," who are eligible for health insurance coverage through both Medicare and Medicaid. It also looks at the differences between "full Medicaid" and "supplemental Medicaid" dual eligibles and the ongoing challenges associated with enrollment and eligibility, integration and coordination, and managed care. The paper presents several examples of integrated care programs designed to better serve the dual-eligible population, including the Program of All-Inclusive Care for the Elderly, Evercare, social health maintenance organizations, and state/federal initiatives such as the Wisconsin Partnership Program, Texas STAR+PLUS, and others. Finally, it considers the implications for dual eligibles of the House and Senate Medicare prescription drug proposals.
