CO-8 Denial Code: Procedure code inconsistent with provider type/specialty

The procedure code is inconsistent with the provider type or specialty (taxonomy).

Why CO-8 happens

  • Rendering provider's taxonomy doesn't support the billed service
  • Wrong rendering NPI on the claim line

How to fix a CO-8 denial

  1. 1

    Verify the rendering provider and their taxonomy code

  2. 2

    Correct the NPI/taxonomy or reassign to the correct provider

How to prevent it

Map billable services to provider taxonomies in your PM system.
