Denial Code CO-208: NPI Not Matched
What Does Code 208 Mean?
National Provider Identifier - not matched. The NPI on the claim does not match the payer's records for the billing or rendering provider.
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?
NPI is valid but doesn't match the provider or practice in the payer's system.
How to Resolve It
- 1Verify the NPI matches the correct provider/practice
- 2Update the payer's records if the NPI has changed
- 3Resubmit with the correct NPI
