Which Form Locator is used to report the Revenue Code itself on the UB-04 form?

• A. Form Locator 43
• B. Form Locator 42
• C. Form Locator 49
• D. Form Locator 38

Answer: (B)

The main idea here is that every service line on a UB-04 claim carries a four-digit Revenue Code that identifies the category of services provided for payment purposes. The field designated to hold this code is the one that reports the Revenue Code itself, so the payer can apply the correct rate and rules to that line. The Revenue Code groups services (for example, different codes for room and board, radiology, lab, etc.), and this coding drives how the charge is reimbursed. Other fields on the line capture the description, the charge amount, and the number of units, but the Revenue Code field is specifically the location where that four-digit code is reported. If the code is missing or wrong, the payer may deny or misprice the claim because they can’t map the line to the proper payment rules.
