This week, our In Focus section reviews publicly available data on enrollment in capitated financial and administrative alignment demonstrations (“Duals Demonstrations”) for beneficiaries dually eligible for Medicare and Medicaid (duals) in 10 states: California, Illinois, Massachusetts, Michigan, New York, Ohio, Rhode Island, South Carolina, Texas, and Virginia. Each of these states has begun either voluntary or passive enrollment of duals into fully integrated plans providing both Medicaid and Medicare benefits (“Medicare-Medicaid Plans,” or “MMPs”) under three-way contracts between the state, the Centers for Medicare & Medicaid Services (CMS), and the MMP. Rhode Island is the latest state to launch its demonstration, with the first wave of opt-in, voluntary enrollment effective July 1, 2016. As of June 2016, more than 360,000 duals are enrolled in an MMP, according to state and CMS enrollment reports.
