Denial Code CO-11: Diagnosis Inconsistent with Provider Type
What Does Code 11 Mean?
The diagnosis is inconsistent with the provider type. The diagnosis billed is not within the scope of the billing provider's specialty.
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 diagnosis code is outside the typical scope for the provider type.
How to Resolve It
- 1Verify the diagnosis is appropriate for the provider specialty
- 2Correct the diagnosis if in error
- 3If accurate, appeal with justification for why the provider treated the condition
