1. Diagnosis-related group
Medical · Health Insurance Abbreviations
Classification of hospital inpatient stays into groups with similar clinical characteristics and expected resource use, which sets a fixed payment per admission under Medicare's inpatient prospective payment system and many other payers. The DRG is assigned from diagnosis and procedure codes, age, sex and discharge status.
Example: DRG 470: major hip and knee joint replacement without major complications.
Developed at Yale University in the 1970s and adopted by Medicare in 1983, DRGs gave hospitals an incentive to shorten stays. Medicare now uses Medicare Severity DRGs, and many countries use DRG-like systems. In anatomy DRG means dorsal root ganglion.
