What is the purpose of Diagnosis-Related Groups in hospital payment?

• A. They determine patient eligibility for hospital admission.
• B. They classify hospital cases into groups with similar expected costs to determine fixed payments; promote efficiency and standardization.
• C. They set surgeons' fees for procedures.
• D. They define hospital quality metrics for payment adjustments.

Answer: (B)

Diagnosis-Related Groups categorize hospital stays into groups that are expected to use similar levels of hospital resources. In this approach, each DRG has a fixed, predetermined payment amount for an admission, so what the hospital gets from the payer is tied to the group rather than the exact services used. This design drives efficiency and standardization because hospitals are incentivized to manage length of stay and resource use to fit the fixed payment. It also helps payers and providers plan costs and compare performance across institutions. Note that admission decisions are based on clinical need, professional fees for physicians are billed separately, and quality measures may influence adjustments through other payment programs rather than the DRG payment itself.
