N627 Remark Code (Deactivated): Not Payable per MCO Contract

N627 meant the service was not payable under the managed care contract. X12 deactivated it and suggested CARC 256, which now reports the same reason as an adjustment code.

X12 deactivated RARCN627 on July 1, 2014. Payers should no longer use it on new remittances, but it can still appear on older ERAs, corrected claims, and appeals.

What N627 meant

Remark N627 told the provider that its managed care contract did not allow payment for this service. The contract might exclude it, fold it into another payment, or simply not list it as billable for that provider.

What replaced it

X12’s note suggested CARC 256. CO-256 now carries this message as the adjustment reason itself, so a separate remark is unnecessary. Related codes include OA-24 for services covered under capitation, and CO-97 when the service is included in another payment.

If you still see N627

It was active only briefly. For a current contract-based denial, compare the service with your contract terms and fee schedule. If the contract supports payment, file a dispute with the relevant section cited; if not, post the amount as a contractual adjustment and do not bill the member.

CO-256 (Service not payable per managed care contract.): The suggested replacement: service not payable per managed care contract.
OA-24 (Charges are covered under a capitation agreement/managed care plan.): Charges are covered under a capitation agreement or managed care plan.
CO-97 (The benefit for this service is included in the payment/allowance for another service/procedure that has already been adjudicated.): The benefit is included in the payment for another service.

N627 FAQ

Why would a contract make a service non-payable?

Managed care contracts can exclude certain services from separate payment, include them in a capitation or case rate, or limit which services a provider type may bill.

What should I check first?

The contract itself, including exhibits and fee schedules, to confirm whether the service is excluded or bundled. If the contract supports payment, dispute the denial.
