CMS Medicare refers to the federal Medicare program that is administered by the Centers for Medicare & Medicaid Services (CMS), a federal agency within the U.S. Department of Health and Human Services. Medicare is primarily health insurance for people 65 and older, certain younger people with disabilities, and people of any age with End‑Stage Renal Disease.

What CMS Medicare Is

  • Medicare is a national health insurance program that helps cover hospital, medical, and prescription drug costs for eligible people in the United States.
  • CMS is the federal agency that runs Medicare, Medicaid, the Children’s Health Insurance Program (CHIP), and parts of the Affordable Care Act, providing coverage to over 100 million people.

The Four Main Parts

  • Part A (Hospital Insurance) : Covers inpatient hospital care, skilled nursing facility care, hospice, and some home health care; most people do not pay a premium for Part A because they paid Medicare taxes while working.
  • Part B (Medical Insurance) : Covers doctor visits, outpatient care, durable medical equipment, and many preventive services; most people pay a monthly premium for Part B.
  • Part C (Medicare Advantage) : Offers an alternative way to get Parts A and B through private plans approved by CMS, often including extra benefits like vision or dental.
  • Part D (Prescription Drug Coverage) : Helps pay for self‑administered prescription medications through private drug plans or Medicare Advantage plans with drug coverage.

Who Runs It (CMS Role)

  • CMS designs and administers Medicare rules, payments to providers, quality programs, and consumer tools such as Medicare.gov.
  • The Social Security Administration generally handles Medicare enrollment and premium collection, while CMS sets coverage policies and oversees health plans and providers.

Recent / Ongoing Updates

  • CMS has been modernizing Medicare.gov to make it easier to compare and choose coverage, including clearer language and more user‑friendly navigation.
  • CMS also issues ongoing updates each year to premiums, deductibles, and coverage rules for Parts A, B, C, and D, which are published on CMS.gov and Medicare.gov.
