CMS, previously known as the Health Care Financing Administration (HCFA), is a federal agency within the United States Department of Health and Human Services (HHS) that administers the Medicare program and works in partnership with state governments to administer Medicaid, the Children’s Health Insurance Program (CHIP), and health insurance portability standards.

The CMS employs over six thousand people, of whom about four thousand are located at its headquarters in Woodlawn, Maryland. The remaining employees are located in the Hubert H. Humphrey Building in Washington, D.C., the 10 regional offices, and in various field offices located throughout the United States. The CMS Head is the Administrator of the Centers for Medicare & Medicaid Services. The position is appointed by the president and confirmed by the Senate.
