In a DRG-based payment system, what does a higher average DRG weight in a patient mix indicate?

• A. Lower expected payment.
• B. Higher expected payment.
• C. Increased length of stay.
• D. Need for more staff.

Answer: (B)

The key idea is that DRG weights measure how resource-intensive a case is. Each DRG has a weight that represents expected relative costs compared with an average case. When a hospital’s patient mix has a higher average DRG weight, it means, on average, the cases require more services, tests, and care. Under DRG-based payment, reimbursement is determined by multiplying the base payment rate by the DRG weight, so a higher average weight translates directly into higher expected payment.

Length of stay can rise with more complex cases, but the payment signal comes from the DRG weight itself, not LOS. Similarly, staffing needs aren’t the direct payment driver here, since the DRG weight captures resource use that drives reimbursement.
