Definition
The highly-trained surgeons that perform Mohs Micrographic Surgery are specialists both in dermatology and pathology. With their extensive knowledge of the skin and unique pathological skills, they are able to remove only diseased tissue, preserving healthy tissue and minimizing the cosmetic impact of the surgery. Mohs surgeons who belong to the American College of Mohs Surgery (ACMS) have completed a minimum of one year of fellowship training at one of the ACMS-approved training centers in the U.S.

Choose 207ND0101X over the general Dermatology code (207N00000X) when the provider's training or certification is specifically in mohs-micrographic surgery; 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 207ND0101X to Medicare specialty 07 (Physician/Dermatology) and Medicare specialty D7 (Micrographic Dermatologic Surgery). 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.

Using 207ND0101X
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.
