What does B3 denote in the code-field qualifiers?

• A. 0-0A
• B. AC- Attachment Control Number
• C. B3
• D. A1-A4

Answer: (C)

Code-field qualifiers tell you what a code value represents on a UB-04 claim. B3 is the specific qualifier that identifies the value as the Attachment Control Number. In other words, when you see B3, it signals that the following data entry is the Attachment Control Number used to link the claim to its attached documentation. The other options either point to different qualifier groupings or describe the element in text rather than naming the actual qualifier, so they don’t correctly describe what B3 designates.
