Where 207NI0002X sits
- Group: Allopathic & Osteopathic Physicians — code 14 of 238 in the group
- Classification: Dermatology 207N00000X
- Specialization: Clinical & Laboratory Dermatological Immunology 207NI0002X
Choose 207NI0002X over the general Dermatology code (207N00000X) when the provider's training or certification is specifically in clinical & laboratory dermatological immunology; 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
CMS's taxonomy crosswalk links 207NI0002X to Medicare specialty 07 (Physician/Dermatology). That specialty — not the taxonomy code itself — is what Medicare enrollment records and uses for payment. 14,942 practitioners are enrolled under it nationally, and 5 other taxonomy codes map to the same specialty.
Other codes under the same Medicare specialty: 207N00000X Dermatology Physician; 207ND0101X MOHS-Micrographic Surgery Physician; 207ND0900X Dermatopathology Physician; 207NP0225X Pediatric Dermatology Physician; 207NS0135X Procedural Dermatology Physician.

Using 207NI0002X
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.
