What does CMS stand for?

• A. Centers for Medical Services
• B. Centers for Medicare Services
• C. Centers for Medicare and Medicaid Services
• D. Center for Medical and Medicaid Services

Answer: (C)

The main idea here is identifying the full name of the federal agency known by the abbreviation CMS. The correct expansion is Centers for Medicare and Medicaid Services, commonly written as Centers for Medicare & Medicaid Services. This agency, part of the Department of Health and Human Services, administers the Medicare program and oversees Medicaid in partnership with states, along with other health programs.

The other options mix up terms or spelling—Medical vs Medicare, omit Medicaid, or use a singular Center—so they do not reflect the actual agency name.
