CO-140: Patient and insured information mismatch
Triage: Recheck eligibility
By Dr. Daniel Turner, DC · Reviewed September 2, 2026
What does denial code CO-140 mean?
The name, date of birth, or member ID on the claim does not match what the payer has on file.
What does CO-140 usually mean 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 do you fix a CO-140 denial?
- Recheck the card and run a real time eligibility check to see exactly what the payer has on file.
- Correct the member ID, name spelling, or date of birth to match the payer record.
- 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.
How to stop it from happening again
- ✓Enter identifiers exactly as the card shows them, including hyphens and suffixes
- ✓Run eligibility at intake so the payer’s version of the patient is on file from day one
- ✓Fix the chart when a mismatch surfaces so the correction outlives the one claim
