Which of the following best describes where revenue codes are applied on the UB-04 claim?

• A. They indicate patient demographics.
• B. They reflect only room and board charges.
• C. They classify charges by department or service line and attach to each service line.
• D. They represent the admission type.

Answer: (C)

Revenue codes on a UB-04 claim are attached to every service line to classify charges by department or service line. This coding shows exactly which part of the hospital provided the service—such as room and board, radiology, or laboratory—and ties each dollar amount to that specific department. They’re not used to indicate patient demographics, nor are they limited to room and board charges, and they don’t represent admission type. By assigning a revenue code to each service line, the claim clearly groups charges for billing, payment, and analysis.
