Centers for Medicare and Medicaid Services


The Centers for Medicare and Medicaid Services (CMS), previously known as the Health Care Financing Administration (HCFA), is a federal agency within the United States Department of Health and Human Services (DHHS) that administers the Medicare program and works in partnership with State governments to administer Medicaid, the State Children's Health Insurance Program (SCHIP), and health insurance portability standards. In addition to these programs, CMS has other responsibilities, including the administrative simplification standards from the Health Insurance Portability and Accountability Act of 1996 (HIPAA), quality standards in long-term care facilities (more commonly referred to as nursing homes) through its survey and certification process, and clinical laboratory quality standards under the Clinical Laboratory Improvement Amendments.



President Lyndon B. Johnson signed the Social Security Act on July 30, 1965, establishing both Medicare and Medicaid. The Social Security Administration (SSA) became responsible for the administration of Medicare and the Social and Rehabilitation Service (SRS) became responsible for the administration of Medicaid. Both Agencies were organized under what was then known as the Department of Health, Education, and Welfare (HEW).

In 1977, the Health Care Financing Administration (HCFA) was established under HEW. HCFA became responsible for the coordination of Medicare and Medicaid. The responsibility for enrolling beneficiaries into Medicare and processing premium payments remained with SSA.

In 1980 the Department of Health and Human Services was created when HEW was divided into two agencies: the Department of Education and the Department of Health and Human Services (HHS). HCFA became an agency under the Department of Health and Human Services.

On July 1, 2001, HHS Secretary Tommy Thompson renamed HCFA the Centers for Medicare & Medicaid Services (CMS). Secretary Thompson explained that in order "to give the agency a new direction, a new spirit, it is necessary that we give it a new name - one that truly reflects the agency's vital mission to serve millions of Medicare and Medicaid beneficiaries across America."

The previous CMS Administrator, Mark McClellan, MD, PhD, was sworn in on March 25, 2004. On September 5, 2006, McClellan announced his resignation from the post. The current Acting Administrator as of September 20, 2007 is Kerry Weems.


The CMS employs approximately 4,100 employees, of which 2,700 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 listed below, and in various field offices located throughout the United States.
