Quick Explanation
Denial code CO-139 indicates that the claim payment has been adjusted or denied based on the terms of a specific contracted funding agreement between the payer, provider, or employer group. This typically means the services rendered are subject to non-standard reimbursement rates, capitation models, or specific funding limits established under a specialized plan contract.
Common Causes for CO-139
Denials with code CO-139 typically happen for the following specific reasons:
- The services rendered fall under a capitated payment structure where the provider is compensated via fixed monthly rates rather than fee-for-service billing.
- The patient's employer-sponsored plan has specific carve-out provisions or unique funding limitations for certain specialty treatments.
- There is a discrepancy between the provider's active contract terms and the payer's internal system rules regarding the designated funding source for the member's group plan.
How to Prevent CO-139 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Verify patient eligibility and specific plan funding types (such as capitation vs. commercial fee-for-service) prior to rendering services.
- Maintain an up-to-date contract management matrix that clearly identifies carve-outs and employer-specific funding exclusions.
- Configure the billing and practice management system to flag accounts associated with non-standard funding contracts to ensure proper coding and billing pathways.

Denial Code: CO-139 - Contracted funding agreement
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code CO-139: "Contracted funding agreement".
On behalf of the provider, we are appealing the adjustment/denial associated with code CO-139 (Contracted funding agreement) for the enclosed claim. Upon reviewing the patient's benefits and our active participating provider contract, the services billed do not fall under the capitated or carve-out provisions of the contracted funding agreement and should be reimbursed under standard fee-for-service terms. In accordance with CMS guidelines and general contract law governing managed care administration, covered services that are not explicitly restricted by the employer-sponsored or contracted funding agreement must be paid at the established contract rates. We request a manual review of this claim and the active provider agreement to correct this processing error and issue the appropriate reimbursement.
Attached please find:
1. A copy of the original claim.
2. The relevant medical records supporting the service.
3. [Any other supporting documents].
We respectfully request that you reprocess this claim for payment.
Sincerely,
[Your Name]
