Missing Information

AR Guide Knowledge

Claims missing required data or documentation, unprocessable claims, and resubmission.

Denial Decoder

Run this denial through the decoder

Enter the codes from your ERA/EOB and get this workflow with the exact CARC/RARC on your line.

Open Denial Decoder

Check first

Check these before anything else

  • Remark code(s) on the ERA/EOB — they identify the exact issue
  • Original submission vs. what the payer received
  • Edit or scrubber report for the flagged element
  • Missing data vs. invalid data
  • Unprocessable (MA130) vs. a true denial
  • CARC 16 and the accompanying remark code

Verify payer-specific rules: Heads up

The exact data each payer requires, and how it must be submitted, varies. Read the remark code carefully and correct only what was flagged — verify the required format with the payer rather than guessing.

What it means

The claim could not be adjudicated as submitted because something required was missing or incorrect. A remark code usually identifies the specific issue. Claims rejected as unprocessable (e.g., MA130) generally have no appeal rights until they are corrected and resubmitted — resubmitting an unchanged claim returns the same result.

Common causes

  • Missing or invalid modifier
  • Incorrect or missing patient or provider information
  • Incomplete coding or missing required fields
  • Missing attachments or supporting documentation
  • Claim rejected by an edit before adjudication

AR Guide knowledge

What AR should verify

  • Read the remark code(s) that accompany the denial to identify the exact issue
  • Compare the claim to the original submission
  • Check the claim scrubber or edit report for the flagged element
  • Confirm the corrected claim clears the original edit

Recommended workflow

What to do next

  1. Fix the specific flagged element and resubmit
  2. Do not resubmit an unchanged claim expecting a different result
  3. If the claim is unprocessable (e.g., MA130), correct it rather than appeal
  4. Document what was corrected so the resubmission can be audited

Don’t assume

Avoid these shortcuts

  • The claim was denied — it may be unprocessable and only need correction
  • Resubmitting the same claim will get a different result
  • The payer knows what's missing — the remark code is what identifies it
  • This is an appeal situation (it is usually a correction)
  • The remark code applies to the whole claim — it may be line-specific

AR Guide knowledge

Documentation

  • The original claim and the corrected version
  • The remark code that identifies the missing element
  • Edit or scrubber report showing the flagged field

AR Guide knowledge

Escalation

  • QA: when the same claim fails edits repeatedly, review the billing workflow
  • Supervisor: when the payer cannot identify the missing element
  • Coding: when the issue is a coding or modifier error

QA checkpoint

Confirm before closing

  • Document the correction reason on the account
  • Verify the resubmitted claim clears the original edit
  • Track recurring edit failures to fix the source of the error
