CO-47 Denial Code Explained

CO-47 is a medical billing denial code that indicates the claim was denied because the service was provided by an out-of-network provider or outside payer network coverage rules. This denial commonly occurs when providers are not contracted with the insurance payer.

What Does CO-47 Mean?

The CO-47 denial code means the insurance payer determined the billed services were performed outside the patient’s approved insurance network or payer contract requirements.

This denial is often related to network participation or coverage limitation issues.

Common Reasons for CO-47

• Out-of-network provider services

• Non-participating provider billing

• Network coverage restrictions

• Incorrect payer billing

• Insurance plan network limitations

• Missing referral approvals

How To Fix CO-47

Verify the patient’s insurance network coverage and confirm provider participation status before resubmitting the claim. Providers may need to submit referral approvals, corrected billing information, or discuss patient financial responsibility if out-of-network coverage does not apply.

Insurance verification before treatment can help reduce future denials.
