Medicare is a health insurance program that was an initiative taken by the federal government to provide health care coverage. The program has been designed for people who are older than 65 years , some people under 65 years of age, those who are receiving Social Security Disability Insurance (SSDI) for a specific time or those who are suffering from End-Stage Renal Disease (ESRD).
A federal agency named Centers for Medicare & Medicaid Services (CMS) is responsible for running the Medicare Program. The funding of the program is done through Social Security and Medicare taxes that all individuals pay on their income and through premiums paid by the people who have been enrolled for the Medicare plan. Some part is also funded by the federal budget.
