Quick Explanation
Denial code CO-114 occurs when a payer rejects a claim because the billed procedure, laboratory test, vaccine, or medical device lacks the required regulatory approval or clearance from the Centers for Disease Control and Prevention (CDC) or related federal agencies. This typically indicates that the service or product is flagged as experimental, investigational, or outside established public health guidelines.
Common Causes for CO-114
Denials with code CO-114 typically happen for the following specific reasons:
- Billing for an investigational vaccine, emergency use authorization (EUA) diagnostic test, or protocol that lacks official CDC or FDA clearance.
- Using a Category III CPT code or new technology code that does not meet the established national coverage determinations or CDC-approved clinical guidelines.
- Omission of required investigational device exemption (IDE) numbers, clinical trial identifiers, or specific modifiers (such as Q0 or Q1) on the claim form.
- Administering a specialized laboratory test or public health procedure without documented compliance with CDC-mandated criteria or registries.
How to Prevent CO-114 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Verify the FDA and CDC clearance status, including Emergency Use Authorizations (EUA), for all new vaccines, laboratory tests, and medical products prior to billing.
- Ensure the electronic health record and chargemaster are updated to flag procedures that require specific investigational modifiers or clinical trial registry numbers.
- Implement a pre-billing review process to confirm that clinical documentation clearly demonstrates adherence to CDC-approved protocols.
- Train coding staff to append appropriate modifiers and include supporting clinical trial or IDE documentation when submitting claims for emerging technologies.

Denial Code: CO-114 - Procedure/product has not been approved/cleared by the Centers for Disease Control
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code CO-114: "Procedure/product has not been approved/cleared by the Centers for Disease Control".
We are appealing the denial of the billed procedure/product under code CO-114. The service provided to the patient is fully compliant with federal standards and meets all medically necessary criteria. Contrary to the denial reason, this procedure/product has received the necessary clearances/authorizations from the CDC and FDA (as outlined in the attached regulatory approval documentation). Under CMS guidelines and standard medical protocols, this service is recognized as safe, effective, and indicated for the patient's clinical presentation. We have enclosed the patient's medical records, the relevant CDC/FDA clearance letters, and clinical efficacy documentation to support this claim, and we respectfully request that this denial be overturned and the claim processed for payment.
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]
