How Did Medicare's Prospective Payment System Affect Hospitals?

Abstract

Using data from 1982 and 1984, we examined how Medicare's prospective payment system affected hospitals. The study showed that hospitals paid through the prospective payment system had significantly lower increases in Medicare costs and greater declines in Medicare use than did other hospitals. Unlike these other hospitals, for which Medicare costs approximately equaled Medicare revenues, hospitals receiving prospective payment kept Medicare costs from rising as fast as Medicare revenues, earning the profit that the prospective payment system allowed.
