CO-170

Payment denied when performed by this type of provider

Contractual obligation; provider write-off unless appealed

What it means
The rendering provider's type or license is not eligible to bill this service under the plan.
Likely cause
Pre-licensed associates or residents billed under their own NPI instead of the supervising provider, a very common group-practice failure.
How to fix it
Bill under the credentialed supervising provider where contracts allow, and keep a credentialing matrix by payer and license type.
Revenue impact
Large, systemic, and quietly expensive for growing group practices.
