diagnosis-Related Groups (DRG) a system of classification or grouping of patients according to medical diagnosis for purposes of paying hospitalization costs. In 1983, amendments to Social Security contained a prospective payment plan for most Medicare inpatient services in the United States. The payment plan was intended to control rising health care costs by paying a fixed amount per patient. The program of DRG reimbursement was based on the premise that similar medical diagnoses would generate similar costs for hospitalization. Therefore, all patients admitted for a surgical procedure such as hernia repair would be charged the same amount regardless of actual cost to the hospital. If a patient's hospital bill should total less than the amount paid by Medicare, the hospital is allowed to keep the difference. If, however, a patient's bill is more than that reimbursed by Medicare for a specific diagnosis, the hospital must absorb the difference in cost. See also appendix of Diagnosis-Related Groups.
