Definition
A dermatopathologist has the expertise to diagnose and monitor diseases of the skin including infectious, immunologic, degenerative and neoplastic diseases. This entails the examination and interpretation of specially prepared tissue sections, cellular scrapings and smears of skin lesions by means of routine and special (electron and fluorescent) microscopes.

Where 207ND0900X sits
- Group: Allopathic & Osteopathic Physicians — code 15 of 238 in the group
- Classification: Dermatology 207N00000X
- Specialization: Dermatopathology 207ND0900X
Choose 207ND0900X over the general Dermatology code (207N00000X) when the provider's training or certification is specifically in dermatopathology; 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 207ND0900X 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.

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.
