Diagnosis-related groups (DRGs) are best described as

• A. A payment system that categorizes diagnoses, treatments, and patient characteristics to reimburse hospitals a fixed amount per case.
• B. A plan that requires a primary care physician.
• C. A system that pays per day of hospital stay.
• D. A private insurer reimbursement model.

Answer: (A)

DRGs are a prospective payment system that groups hospital admissions into categories based on similar diagnoses, treatments, and patient characteristics so hospitals are paid a fixed amount for each discharge. This fixed per-case payment is determined by the DRG category (often with weightings for severity and regional cost adjustments), which standardizes reimbursement and encourages efficient care. Because payment depends on the assigned DRG rather than the actual services billed or days of stay, the system motivates hospitals to avoid unnecessary procedures and shorten stays when appropriate. It’s not about requiring a primary care physician, nor about paying per day of hospitalization, and while insurers—private or public—may use DRG-style methods, the defining feature is the fixed amount per case tied to the DRG category.
