The Center for Medicare and Medicaid Innovation is an organization of the United States government under the Centers for Medicare and Medicaid Services (CMS). It was created by the Patient Protection and Affordable Care Act, the 2010 U.S. health care reform legislation. "The center is to test innovative payment and delivery system models that show important promise for maintaining or improving the quality of care in Medicare, Medicaid, and the Children's Health Insurance Program (CHIP), while slowing the rate of growth in program costs". The center "is to give priority to twenty models specified in the law, including medical homes, all-payer payment reform, and arrangements that transition from fee-for-service reimbursement to global fees and salary-based payment". It is "intended to overcome antireform inertia by creating a mechanism for the diffusion of successful pilot programs" without requiring Congressional approval.
The Center has often been called the CMMI, from its initials. Its own website uses CMS Innovation Center as a short informal name.
