Under the PPS, what determines the fixed payment for a hospital stay?

• A. The length of stay
• B. The patient’s diagnosis related group (DRG)
• C. The hospital’s overall performance
• D. The geographic location of the hospital

Answer: (B)

The fixed payment for a hospital stay under the Prospective Payment System (PPS) is determined by the patient’s diagnosis related group (DRG). This system categorizes hospital cases into groups that are expected to have similar hospital resource use. When a patient is admitted to the hospital, their diagnosis is assigned a DRG, which then determines the lump-sum payment that the hospital will receive for the treatment of that patient, regardless of the actual length of stay or resources used. This approach incentivizes hospitals to provide efficient care while managing costs, as they are paid a fixed amount for a defined set of services related to a specific diagnosis.

The other factors listed, such as the length of stay, hospital performance, or geographic location, can influence the operation of hospitals or affect their financial performance, but they do not directly determine the fixed payment under the PPS, which is fundamentally tied to the diagnosis related group assigned to the patient.
