What N574 means

The ordering or referring provider's type or specialty is not one the payer allows to order or refer this service.

Payers can limit who may order certain services, and some require the ordering provider to be enrolled as eligible to order and refer. N574 means the provider listed did not qualify.

It usually supports a reason code about the ordering or referring provider. Check the provider information on the claim and with the ordering provider before assuming the order is invalid.

Common causes

• The ordering provider is not enrolled with the payer as eligible to order or refer.
• A provider type that cannot order this service, under payer rules, was listed.
• The wrong provider was entered in the ordering field, such as the rendering provider.

What to do next

1. Confirm the ordering provider listed is the one who actually wrote the order.
2. Check the ordering provider's enrollment and specialty with the payer.
3. Correct the ordering provider on the claim, or ask the ordering provider to enroll.
4. Resubmit once the ordering information is fixed.
