What is a DRG?

• A. Direct Reimbursement Group
• B. Doctor's Relative Grade
• C. Diagnosis-Related Group used for hospital reimbursement
• D. Diagnostic Response Guidance

Answer: (C)

A DRG is a Diagnosis-Related Group used to reimburse hospitals. In this system, inpatient cases are sorted into groups that reflect similar diagnoses and expected resource use. Each DRG carries a fixed payment amount, determined in advance, based on historical costs for that group. The hospital receives the same rate for any given admission within that DRG, regardless of the actual length of stay or exact resources used, which helps standardize payments and incentivize efficient care. The concept is not about direct reimbursement categories, a doctor’s rank, or diagnostic guidance, which is why the option describing a Diagnosis-Related Group used for hospital reimbursement is the correct one.
