Choose 111NT0100X over the general Chiropractor code (111N00000X) when the provider's training or certification is specifically in thermography; 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.

Using 111NT0100X
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.
