In the Medicare IPPS system, what does DRG stand for and what is its role?

• A. Diagnosis- Related Group; determines fixed payment category for discharge
• B. Daily Revenue Group
• C. Diagnostic Reimbursement Group
• D. Discharge-Reason Group

Answer: (A)

Diagnosis-Related Group is the term used to classify inpatient stays into fixed-payment categories under Medicare’s Inpatient Prospective Payment System. The DRG assigns a discharge to a payment category so the hospital receives a predetermined amount for that stay, based on the assigned DRG (with adjustments for factors like severity, case mix, and location). This mechanism standardizes payments across similar cases, rather than paying by day or by individual charges. The other terms listed aren’t part of this system.
