Definition

A dentist who assesses, diagnoses, and treats patients with complex chronic orofacial pain and dysfunction disorders, oromotor and jaw behavior disorders, and chronic head/neck pain. The dentist has successfully completed an accredited postdoctoral orofacial pain residency training program for dentists of two or more years duration, in accord with the Commission on Dental Accreditation's Standards for Orofacial Pain Residency Programs, and/or meets the requirements for examination and board certification by the American Board of Orofacial Pain.

Where 1223X2210X sits

Choose 1223X2210X over the general Dentist code (122300000X) when the provider's training or certification is specifically in orofacial pain; the general code covers the classification as a whole. A provider may report more than one taxonomy code on an NPI but marks one as primary.

Medicare

1223X2210X has no entry in the CMS Medicare Provider and Supplier Taxonomy Crosswalk. That usually means Medicare does not enroll this kind of provider under its own specialty — the provider can still hold an NPI and use this code on claims to other payers.

Using 1223X2210X

The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
