Which statement correctly contrasts DRGs and APCs?

• A. APCs are used for inpatient reimbursement; DRGs are used for outpatient reimbursement.
• B. DRGs and APCs are interchangeable in inpatient settings.
• C. DRGs are used for inpatient reimbursement, while APCs are used for outpatient reimbursement.
• D. APCs are used for physician services in hospitals, DRGs for nursing services.

Answer: (C)

The main concept here is how payment systems distinguish between inpatient and outpatient hospital services. DRGs (Diagnosis-Related Groups) are used for inpatient reimbursement under the inpatient prospective payment system; they group an entire hospital admission by diagnosis and expected resource use, and pay a single fixed amount per admission (with adjustments for severity and comorbidities). APCs (Ambulatory Payment Classifications) are used for outpatient reimbursement under the outpatient prospective payment system; they categorize individual outpatient services so the facility is paid for each outpatient encounter based on the specific services provided. This makes the statement that DRGs apply to inpatient reimbursement and APCs apply to outpatient reimbursement the correct contrast. For reference, the other options misstate who is paid under each system or mix inpatient/outpatient roles or physician vs. facility charges.
