OA-140: Patient ID Number and Name Do Not Match

What Does OA-140 Mean?

OA-140 may appear when the identification mismatch is flagged as an administrative processing issue rather than a contractual obligation. The practical resolution is the same — correct the member ID and name and resubmit.

CARC 140 is a straightforward identity verification failure. The payer looked at the member ID number and the patient name on your claim, compared them to their enrollment database, and found they do not match. The payer cannot process the claim because they cannot confirm who the patient is. This is not a coverage denial, a coding issue, or a medical necessity dispute — it is purely a data problem.

The most common cause is a data entry error — a transposed digit in the member ID, a misspelled name, or a name formatted differently than the payer expects (e.g., including or omitting a middle initial). Name changes are the second most frequent trigger, especially when a patient gets married, divorced, or legally changes their name but either the provider or the payer has not updated their records. Insurance card turnover is another common source — patients receive new member IDs when they change plans, employers, or plan years, and the old ID may still be in the provider's system.

From a workflow standpoint, CARC 140 is one of the most preventable denial codes. It can almost always be avoided by verifying patient demographics against the insurance card at check-in and running an eligibility check before claim submission. When you do receive this denial, resolution is typically fast — identify the correct member ID and name, update the claim, and resubmit.

How to Resolve

Compare the member ID and patient name on the claim against the insurance card and payer records, correct the mismatch, and resubmit.

1. Identify the mismatch Determine whether the issue is the member ID, the patient name, or both by comparing against the insurance card and payer records.
2. Correct and resubmit Update the mismatched fields and resubmit the claim with corrected identification information.
