How should UB-04 data be validated before submission?

• A. Check for required fields, correct dates/codes, accurate payer data, and run pre-submission edits or test files.
• B. Validation is optional and only for large facilities.
• C. Validation is performed after submission by the payer.
• D. Only diagnosis codes need validation.

Answer: (A)

Validating UB-04 data before submission focuses on ensuring the claim has all required fields, uses correct dates and codes, and contains accurate payer information, so it passes system edits on the first try. This is done by running pre-submission edits or using test files that simulate real submissions. These checks catch missing or inconsistent data—like missing patient or provider identifiers, invalid dates, or incorrect codes—before the claim leaves your system. When data is clean from the start, denials drop, submission cycles speed up, and reimbursement happens more smoothly.

Validation isn’t optional for any facility; it’s a standard practice because errors can come from many areas, not just diagnoses. Validation after submission is the payer’s job to review and adjudicate, but the goal is to prevent those post-submission issues in the first place. And it’s not only about diagnosis codes—numerous data elements (patient, dates, payer data, revenue codes, procedure codes, modifiers, etc.) must be correct and aligned.
