What N808 means

The payer does not cover this service when it is performed by this provider type or specialty.

N808 is a coverage decision about who did the service. The plan covers the service, but not when furnished by this kind of provider, for example a service the plan pays only to physicians or only to certain specialties.

It usually explains reason code 185 or 170. It differs from a billing restriction in that the service itself is not covered for this provider.

Common causes

• The plan covers the service only from certain licensed provider types.
• The provider's enrolled specialty is not one the plan allows for this service.
• A midlevel or assistant performed a service the plan limits to supervising physicians.

What to do next

1. Check the plan's policy on which provider types are covered for the service.
2. Confirm the specialty and taxonomy on file match the provider's actual credentials.
3. Rebill under the eligible provider if they performed or directly supervised the service and the plan allows it.
4. Appeal if the provider type should be covered under the plan documents.
