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 benefits (duals) in nine states. California, Illinois, Massachusetts, Michigan, New York, Ohio, South Carolina, Texas, and Virginia have begun either voluntary or passive enrollment of duals for fully integrated Medicaid and Medicare benefits under a three-way contract with the Centers for Medicare & Medicaid Services (CMS) and health plans, known as Medicare-Medicaid Plans (MMPs). Rhode Island has also established a demonstration with CMS, but has not begun enrollment. As of June 2015, nearly 350,000 duals are enrolled in an MMP, based on state and CMS enrollment reporting.
