The fairness of the PPS reimbursement methodology
1Office of Technology Assessment, U.S. Congress, Washington, DC.
Abstract:
In FY 1984 the Medicare program implemented a new method of reimbursing hospitals for inpatient services, the Prospective Payment System (PPS). Under this system, hospitals are paid a predetermined amount per Medicare discharge, which varies according to certain patient and hospital characteristics. This article investigates the presence of systematic biases and other potential imperfections in the PPS reimbursement methodology as revealed by its effects on Medicare operating ratios. The study covers the first three years of the PPS (approximately 1984-1986) and is based on hospital data from the Medicare cost reports and other related sources. Regression techniques were applied to these data to determine how Medicare operating ratios were affected by specific aspects of the reimbursement methodology. Several possible imbalances were detected. The potential undercompensation relating to these can be harmful to certain classes of hospitals and to the Medicare populations that they serve.
Insights
The Prospective Payment System (PPS) for Medicare hospitals, implemented in 1984, may have systematic biases. Analysis of early PPS data revealed potential undercompensation, which could negatively impact certain hospitals and Medicare patients.
Area of Science:
- Health Economics
- Healthcare Policy
- Medical Services Research
Background:
- Medicare's Prospective Payment System (PPS) was introduced in 1984 for inpatient services.
- PPS reimburses hospitals a set amount per Medicare discharge based on patient and hospital factors.
Purpose of the Study:
- To investigate systematic biases and imperfections in the PPS reimbursement methodology.
- To assess the impact of PPS on Medicare operating ratios.
Main Methods:
- Analysis of hospital data from Medicare cost reports (1984-1986).
- Application of regression techniques to evaluate PPS effects on operating ratios.
Main Results:
- Detected several potential systematic imbalances within the PPS reimbursement methodology.
- Identified potential undercompensation for specific hospital types.
Conclusions:
- The PPS reimbursement methodology may contain imperfections leading to undercompensation.
- These imbalances can adversely affect certain hospitals and the Medicare populations they serve.
