What do HCPCS/CPT codes on UB-04 specify?

• A. They specify the exact service or procedure performed for that line item.
• B. They indicate the room type.
• C. They control the facility's staffing levels.
• D. They list the patient's emergency contact.

Answer: (A)

HCPCS/CPT codes on the UB-04 specify the exact service or procedure performed for that line item. They are the standardized language used to describe what was done, such as a diagnostic test, a procedure, or medication administration. Each line on the claim ties a CPT/HCPCS code to a unit quantity and a revenue code that places it in the correct department, so the payer knows precisely what was billed and can determine reimbursement and reporting. These codes do not convey room type, staffing levels, or the patient’s emergency contact.
