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. As of November 2017, more than 400,000 duals are enrolled in an MMP, the second-highest monthly enrollment since the demonstrations began, according to state and CMS enrollment reports.
