Which pps provides a predetermined payment that depends on the patients principal diagnosis?

The Payment Per Stay (PPS) that provides a predetermined payment based on the patient's principal diagnosis is known as the Diagnosis-Related Group (DRG) system. This system is primarily used in inpatient hospital settings, where payment is determined by the patient's diagnosis, procedures performed, and other factors. Under DRG, hospitals receive a fixed payment amount for each patient, encouraging efficiency in care delivery.
