Patient/Insured ID and Name Mismatch (Registration)
The insurance ID number and the patient/subscriber name submitted on the claim do not match what the payer has on file, so the payer's system cannot locate the correct member record to adjudicate the claim.
Guided troubleshooter available for this denial
Answer a few questions to reach the correct disposition. No patient or claim identifiers requested.
In plain language
The insurance ID number and the patient/subscriber name submitted on the claim do not match what the payer has on file, so the payer's system cannot locate the correct member record to adjudicate the claim.
Start here
Re-verify eligibility directly with the payer (portal, 270/271 transaction, or phone) using the patient's date of birth and any available ID fragment.

Billing/Claims follow-up
Who prevents it
Patient Access/Registration — accurate capture of legal name and insurance ID at check-in, including verification against a scanned or swiped insurance card rather than manual entry alone.
How to resolve this denial, step by step
- 1
Re-verify eligibility directly with the payer (portal, 270/271 transaction, or phone) using the patient's date of birth and any available ID fragment.
- 2
Compare the payer's returned name/ID exactly against what was submitted on the claim.
- 3
Correct the demographic and/or ID fields in the practice-management system.
- 4
Resubmit as a corrected claim (not a new original claim) to avoid triggering a duplicate- claim edit.
- 5
Update the patient's stored record so the corrected information carries forward to future encounters.
Then choose the correct disposition
Corrected claim
appropriate once the accurate name/ID combination is confirmed with the payer; this is a data-matching issue, not a benefit or medical-necessity determination, so no formal appeal is typically needed.
Appeal
rarely applicable; reserved for the unusual case where the payer's own eligibility file is wrong and the payer requires a formal dispute process to correct it.
Stop and escalate when
- The payer's eligibility response does not match any name/ID combination the patient or registration has on file; repeated CO-140 denials for the same patient across multiple visits, suggesting a systemic registration data-entry issue.
What Needs to Be Corrected
- A. Claim-data correction: Correct the patient/subscriber name and/or ID number on the claim to exactly match the payer's eligibility record, then resubmit as a corrected claim.
- B. Upstream operational correction: If the registration system consistently stores an incorrect name format (e.g., nickname instead of legal name) for this patient, correct the patient's demographic record at the source so future claims do not repeat the error.
Do Not Do This
- Do not guess at a corrected ID number without confirming it against a payer eligibility response or the insurance card; an incorrect guess can trigger repeat denials or misdirect the claim to the wrong member's record.
- Do not resubmit as a brand-new original claim without referencing/replacing the original (this can trigger a duplicate-claim CARC 18 denial in addition to the original issue).
