OA-224: Patient Identity Compromised

What Does OA-224 Mean?

OA-224 appears when the identity compromise is being investigated across multiple payers or involves a more complex fraud investigation. The claim is held under OA pending resolution of the broader investigation. The resolution path is the same as CO-224 but may take longer due to the multi-party investigation.

CARC 224 is a fraud-prevention hold — the payer has determined or suspects that the patient's identity has been compromised through identity theft, and all claims under that identity are frozen until verification is completed. This is not a clinical denial, a coding error, or a coverage issue. It is a security measure designed to prevent fraudulent claims from being paid.

When you receive CARC 224, the patient's account has been flagged in the payer's system. This may have been triggered by the patient reporting identity theft, the payer detecting suspicious claims patterns, a data breach affecting patient records, or demographic mismatches between your claim submission and the payer's records. The flag applies not just to the current claim but to all future claims until the identity is re-verified.

Resolution requires direct coordination between three parties: the provider, the patient, and the payer's fraud or special investigations unit. The provider's role is to verify the patient's identity at the practice level (government-issued ID, insurance card verification), assist the patient in reporting the theft if confirmed, and then work with the payer to clear the hold. This process can take weeks depending on the complexity of the investigation. Do not bill the patient for these claims while the identity hold is active — the charges remain in a holding status until the payer can confirm the legitimacy of the claims.

Common Causes

How to Resolve

Verify the patient's identity at your practice, coordinate with the payer's fraud unit to clear the identity hold, then resubmit the claim.

1. Contact the fraud investigation unit Reach out to the payer's fraud unit to determine the scope of the investigation and what documentation is needed from your practice.
2. Provide verification and monitor Submit all requested identity verification documents and track the investigation status. Request updates at regular intervals until the hold is resolved.
