Claim Adjustment Reason Codes-CARC Codes

Claim Adjustment Reason Codes list or CARC Codes List are standardized codes used in the healthcare industry to explain adjustments and denials made to medical claims submitted by providers to insurance companies or other payers. These codes help communicate the reasons for changes in the payment amount or the denial of a claim.

What are CARC codes?

Claim Adjustment Reason Codes (CARCs) are standardized codes used in the medical billing and healthcare industry to explain the reasons for adjustments or denials made to medical claims.

When a provider submits a claim for reimbursement to an insurance company or payer, the claim may undergo review and processing. During this process, the payer may identify certain issues that require adjustments to the payment or result in the denial of the claim.

These codes are standardized by the American National Standards Institute (ANSI) and the Centers for Medicare & Medicaid Services (CMS).

Here are a few examples of Claim Adjustment Reason Codes (CARCs) and their meanings:

1. CA 29: “The time limit for filing has expired.” This code might be used when a claim is submitted after the allowed time frame for submission has passed.
2. CA 97: “The benefit for this service is included in the payment/allowance for another service/procedure that has already been adjudicated.” This code indicates that the payment for a specific service is bundled or included within the payment for another related service.

If you come within either exception, or if you believe the carrier was wrong in its determination that we do not pay for this service, you should request appeal of this determination within 30 days of the date of this notice. Your request for review should include any additional information necessary to support your position. If you request an appeal within 30 days of receiving this notice, you may delay refunding the amount to the patient until you receive the results of the review. If the review decision is favorable to you, you do not need to make any refund.
