Denial Code CO-185: Rendering Provider Not Eligible
What Does Code 185 Mean?
The rendering provider is not eligible to perform the service billed. This may be due to licensing, credentialing, or network status.
Group Code CO (Contractual Obligation): The provider has agreed to accept the payer's determination. The patient is generally not responsible for this amount.
Why Does This Happen?
The rendering provider is not credentialed with the payer or is out-of-network.
How to Resolve It
- 1Verify the provider's credentialing status with the payer
- 2If credentialing is pending, submit proof of application
- 3Consider billing under a credentialed supervising provider if appropriate
