A way of determining payments to hospitals, used under Medicare’s prospective payment system (PPS) and by some other public and private payers. The DRG system classifies patients into groups based on the principal diagnosis, treatments and other relevant criteria. Hospitals are paid the same for each case classified in the same DRG, regardless of the actual cost of treatment.
