What happens when UB-04 data are missing required fields?

• A. Immediate payment
• B. Denials and resubmissions
• C. Automatic approval
• D. No impact

Answer: (B)

When UB-04 data are missing required fields, the claim cannot be properly adjudicated, so it is denied and must be resubmitted with complete information. Payers rely on these fields to correctly identify the patient, provider, facility, dates of service, and the clinical details (diagnoses and procedures) needed to determine coverage and payment. Without them, the system can’t map the service or assign the right codes, leading to a denial or rejection rather than any payment.

This means there is no automatic payment and no impact guarantee until the missing data are corrected and the claim is resubmitted. The best path is to fix the missing fields—ensuring all required data are present and accurate—and resubmit, which then allows the claim to be reprocessed for payment.
