CO-140: Patient and insured information mismatch

Triage: Recheck eligibility

What CO-140 means

The name, date of birth, or member ID on the claim does not match what the payer has on file.

What it usually means in a chiropractic office

Usually a typo at intake, a nickname where the card shows a legal name, a member ID copied with or without a dash the payer expects the other way, or a dependent billed under the wrong subscriber.

How to work it

  1. Recheck the card and run a real time eligibility check to see exactly what the payer has on file.
  2. Correct the member ID, name spelling, or date of birth to match the payer record.
  3. Resubmit as a corrected claim.

What this looks like in practice

The card says Jonathan, the chart says Jon, and the payer record was built from the employer roster with a middle initial. Two of three claims for the family process and the third denies CO-140. Eligibility run with the exact card data shows the payer’s version of the name, the chart is corrected, and the resubmission pays.
