What N574 means

Labs, imaging centers, DME suppliers, and therapists often bill for services someone else ordered. Payers check that the ordering or referring provider on the claim is allowed to order that kind of service. N574 says the provider you reported is, according to the payer’s records, a type or specialty that cannot order or refer.

It usually accompanies CARC 183 (referring provider not eligible) or CARC 184 (ordering provider not eligible).

Common causes

The wrong provider was entered in the ordering or referring field, such as a nurse or staff member who handled the paperwork.
The ordering provider’s enrollment lists a type or specialty that the payer does not permit to order.
The NPI in box 17b belongs to an organization rather than the individual practitioner.
The provider is not enrolled with the payer in a way that allows ordering.

How to fix it

Check the order. Confirm who actually signed it.
Verify the name and NPI in boxes 17 and 17b match that individual.
If the claim was wrong, submit a corrected claim with resubmission code 7 in box 22.
If the claim was right, contact the ordering provider’s office. They need to review and update their enrollment or specialty with the payer.
Resubmit once the payer’s record is fixed, if the payer allows reprocessing for past dates.

How to prevent it

Validate ordering and referring providers against the payer’s enrollment lookup at intake, before performing non-urgent services. See authorization and referral denials.

N574 FAQ

Why would a valid clinician be ineligible to order?

Payers often limit ordering and referring to certain provider types. In Medicare, for example, the provider must be enrolled or opted out and be of an eligible type. A specialty recorded incorrectly in the payer's file can also trigger N574.

Is this the billing provider's fault?

Not always. The data may belong to the ordering provider, but the claim that is denied is yours, so you need to follow up.

Can I just change the ordering provider?

Only to the provider who actually ordered or referred the service, as shown in the record. Substituting a different provider is not appropriate.
