Trustees Report & Trust Funds

The Medicare Program is the second-largest social insurance program in the U.S., with 48.7 million beneficiaries and total expenditures of $549 billion in 2011. The Boards of Trustees for Medicare (also Boards) report annually to the Congress on the financial operations and actuarial status of the program. Beginning in 2002, there is one combined report discussing both the Hospital Insurance program (Medicare Part A) and the Supplementary Medical Insurance program (Medicare Part B and Prescription Drug Coverage). The Office of the Actuary in the Centers for Medicare & Medicaid Services (CMS) prepares the report under the direction of the Boards.

The Boards of Trustees issued their most recent report on April 23, 2012.

The Trustees Report is a detailed, lengthy document, containing a substantial amount of information on the past and estimated future financial operations of the Hospital Insurance and Supplementary Medical Insurance Trust Funds (see the links in the Downloads section below). We recommend that readers begin with the "Overview" section of the report. This section is fairly short, is written in "plain English," and summarizes all the key information concerning the expected financial outlook for Medicare. Substantial additional material is available in the later sections for those wishing to delve more deeply into the actuarial projections.
