What service gets grouped and paid based on DRG?

• A. Outpatient clinic visits
• B. Emergency department visits
• C. Inpatient services
• D. Home health visits

Answer: (C)

DRGs (Diagnosis-Related Groups) are a payment method used to reimburse inpatient hospital stays. They classify hospital discharges into groups that reflect similar clinical conditions and resource use, so a single prospective payment amount can cover the entire stay. Because of this, the service most appropriately associated with DRGs is inpatient services—when a patient is admitted and stays in the hospital, the payment is grouped into a DRG.

Outpatient clinic visits and emergency department visits fall under outpatient payment systems (often using ambulatory payment classifications rather than DRGs), while home health visits are paid under the Home Health Prospective Payment System, which uses its own case-mix adjustments.
