In general, work that CMS currently performs helps to fulfill either its mission as a health care insurance provider or reflects its mandate to help improve health care quality. CMS’s core tasks include “processing billions of claims, addressing millions of inquiries and appeals, and conducting thousands of health care facility inspections and complaint investigations. CMS manages and supports its prescription drug plans, Medicare Advantage plans, employer-sponsored retiree health care coverage, and various administrative grants. The agency works with various states, regions, and providers to facilitate enrollment of millions of eligible recipients and to develop policies for cost-effective and quality health care.”2
