CO-281: Deductible Waived Per Contractual Agreement

What Does CO-281 Mean?

CO-281 is a contractual adjustment that removes the patient's deductible obligation. This is typically a positive outcome — the patient does not owe the deductible, and the provider's reimbursement accounts for the waiver under the contract. Verify the waiver matches your contractual terms.

CARC 281 is unusual among denial codes because it is often a favorable adjustment rather than a denial. It indicates that the patient's deductible obligation has been waived per a contractual agreement between the provider and the payer. The patient does not owe the deductible for the billed service.

This code appears in several scenarios: preventive care services covered without deductible under ACA-compliant plans, value-based or quality program arrangements that waive deductibles for specific services, and special contractual provisions between providers and payers. The waiver is a feature of the benefit design or provider contract, not an error.

Since CARC 281 is used exclusively with Group Code CO, the adjustment is a contractual matter between the provider and payer. The key action is to verify that the waiver is being applied correctly — both in amount and applicability. If the waiver was not applied when it should have been, or if the waiver amount is incorrect, the provider should contact the payer with the contract documentation.

Common Causes

How to Resolve

1. Check contract terms Review your provider-payer contract to confirm the deductible waiver provision and ensure it applies to the billed service.
2. Verify the waiver amount Compare the waiver amount on the remittance against the contractual terms to ensure accuracy.
3. No action if correct If the waiver is applied correctly, no further action is needed.
4. Correct if wrong If the waiver amount is incorrect or was not applied when it should have been, contact the payer with your contract documentation.
