How to Audit a UB-04 Claim Before the Payer Does

Most institutional claim denials are mechanical. A type of bill code whose frequency digit does not exist, an emergency-room line with no procedure code attached, an attending provider NPI that fails its checksum — none of these involve medicine. They are data errors, and they are catchable before submission.

This page demos a UB-04 claim audit, running entirely in your browser on de-identified sample data. Load the case and nine rule families examine every field the way payer front-end edits do — then explain each flag in plain language and suggest the fix.

The Errors Behind Most UB-04 Denials

  • Type of bill mistakes: FL04 carries a facility code, a bill classification, and a frequency digit. A frequency of 9 does not exist — yet it gets keyed constantly.
  • Revenue lines missing their HCPCS: emergency (0450), pharmacy (0250), lab (0300), and CT (0350) lines are priced off the procedure code on FL44. No code, no payment detail, denial.
  • NPI check-digit failures: the tenth digit of every National Provider Identifier is a checksum of the first nine. If it fails, the provider ID cannot exist.
  • Date logic: accident occurrence dates after discharge, service lines outside the statement covers-period, interim bills without matching from/to dates.
  • Zero-unit and zero-charge lines: pricing engines drop them silently, so services quietly go unbilled.

What a Rule-Based UB-04 Audit Actually Checks

A serious claim audit mirrors payer edits, not generic spell-checking. The rules running on this page cover:

  1. Claim header: FL04 validity against the bill-type table, statement covers-period ordering (FL12–13).
  2. Providers: NPI check digits and presence of required attenders (FL76).
  3. Revenue lines: FL42 format, revenue-code↔HCPCS pairing expectations, unit and charge sanity across FL44–49.
  4. Dates and codes: occurrence-code dates against the stay (FL17), per-line service dates inside the span (FL45).

Every flag shows the field, the offending value, why payers reject it, the suggested correction, and a link into our complete UB-04 field reference.

Audit Without Uploading a Single File

The whole engine is client-side JavaScript. Nothing is transmitted, stored, or logged — the privacy story is structural rather than a compliance promise. That makes it safe to run on real figures the moment local parsing ships; today, load the de-identified sample case to see every rule fire.

From Flagged to Clean

Correcting a flagged value re-runs the rules instantly — watch the score recover as flags clear. Export the result as a spreadsheet for your billing team, or hand the case to a human biller who double-checks every line and ships a red-flag report within 24 hours.

Fewer denials start with fewer defects. Run the sample audit above and see what your payer would have caught.
