The Center for Medicare and Medicaid Innovation conducts and sponsors numerous innovative demonstration projects and model tests to measure the effect of potential program changes. Our demonstrations and model tests study the likely impact of new methods of service delivery, coverage of new types of service, and new payment approaches on beneficiaries, providers, health plans, states, and the Medicare Trust Funds. Evaluation projects validate our research and demonstration/model findings and help us monitor the effectiveness of Medicare, Medicaid, and the Children's Health Insurance Program (CHIP).

This page provides information about Medicare Demonstrations conducted by CMS prior to the creation of the Center for Medicare and Medicaid Innovation.
