==History==
President Lyndon B. Johnson signed the Social Security Amendments 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; however, responsibility for enrolling beneficiaries into Medicare and processing premium payments remained with SSA.

The CMS has developed and used several systems to classify Medicare cases. Hospital cases are classified using the Diagnosis-related Group (DRG); outpatient cases are classified using the Ambulatory Patient Group (APG). These systems are used to determine how much Medicare pays the hospital or provider for each service or product.

==Workforce==
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., its 10 regional offices, and in various field offices located throughout the United States.

The head of the CMS is the Administrator of the Center for Medicare & Medicaid Services. The position is appointed by the president and confirmed by the Senate.<ref name="kliff2011">{{cite web |url=http://www.washingtonpost.com/national/health-science/medicare-administrator-donald-berwick-resigns-in-the-face-of-republican-opposition/2011/11/23/gIQA5S7mpN_story.html |title=Medicare administrator Donald Berwick resigns in the face of Republican opposition |author=Kliff, Sarah |work=The Washington Post |date=23 November 2011 |accessdate=23 March 2014}}</ref>
