World of Medicare

Role of CMS

CMS’s mission is to provide effective health care coverage and promote quality care for people with Medicare.

The agency makes sure its contractors and state agencies properly administer Medicare. It also:

  • Issues policy for provider payment
  • Identifies and tests ways to improve health care management and treatment
  • Assesses the quality of health care facilities and services

CMS also works with states to oversee the Medicaid Program, the Health Insurance Marketplace, and the Children’s Health Insurance Program (CHIP).

CMS has regional offices throughout the nation. The CMS website offers more information about the Agency and Medicare.

Medicare system's network: CMS (featured), providers, contractors, organizations.
