How have PPS changes affected allocation of Medicare spending for hospital care? A case study of New York State

Complex national factors went into the development of key policies of the federal prospective payment system, and the effects of these policies varied in different parts of the country. One state particularly affected by these changes, and for the most part in a positive way, was New York. This paper focuses on the Medicare PPS policy changes and their impact nationally. An analysis of the experience of New York state, which had been under a stringent hospital cost containment system before PPS, provides a laboratory to understand how key federal policies affected different types of hospitals in that state as well as nationally.
