Which code would be used to denote a Required field?

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

Answer: (A)

Understanding how data element status communicates whether information is mandatory on UB-04 is key. The code that marks a field as must be completed is B3. It signals that this particular data item is required for the form to be valid and to proceed with billing and claims processing. The other options point to different concepts—one refers to a general range rather than a status indicator, another designates a specific data element (Attachment Control Number), and the last is not the designation used for required fields. So, B3 is the correct choice because it directly denotes a required field.
