In this article, the author reviews expenditure growth trends over Medicare's 35-year history and comments on how the program's long-range financial outlook has changed over time. The author focuses on the various legislative, economic, and demographic factors that have affected expenditure growth and financial status. In addition, Medicare's share of total U.S. health costs is briefly reviewed. In an appended comment, the author considers whether the impact of the Balanced Budget Act of 1997 (BBA) was greater than intended by Congress and the Administration.
