Medicare is a nationwide health insurance program for the aged and certain disabled persons. Medicare consists of four distinct parts: Part A (Hospital Insurance, or HI); Part B (Supplementary Medical Insurance, or SMI); Part C (Medicare Advantage, or MA); and Part D (the prescription drug benefit). The program is administered by the Centers for Medicare & Medicaid Services (CMS). According to the Congressional Budget Office, total program outlays are estimated to reach about $714 billion in fiscal year 2018. Net federal outlays, after deduction of beneficiary premiums and other offsetting receipts, are expected to be close to $590 billion in 2018.
Medicare is administered by CMS within the U.S. Department of Health and Human Services (DHHS). Day-to-day program operations, including processing benefits and paying claims, are conducted by private Medicare contractors.

The summary highlights major legislation; it is not a comprehensive list of all Medicare or health related tax amendments. Included are provisions that had a significant budget impact, changed program benefits, modified beneficiary cost sharing, or involved major program reforms. Provisions involving policy changes are mentioned the first time they are incorporated in legislation, but not necessarily every time a modification is made.
