MOHS-Micrographic Surgery Physician: how many are there, and how many are in private practice?

National totals

What this specialty covers

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.

Reading the sole-proprietor share

For this specialty, 12.5% means that 268 of the 2,141 active records are flagged as sole proprietors in NPPES. The flag is a self-reported NPPES field, so it is an imperfect proxy for private practice and should not be read as a direct count of independently owned Mohs practices or physicians. It may not fully reflect employment, group ownership, affiliations, or billing arrangements.

New NPI registrations by year

Data notes

• The sole-proprietor field is self-reported by the provider in NPPES and is an imperfect proxy for private practice.
• A sole-proprietor count shown as <11 is suppressed: the true value is below 11, which could include zero.
• - NPI counts reflect active records with this taxonomy as the primary classification, not a census of every clinician who performs Mohs surgery.
• - Taxonomy selections and NPPES locations can be updated and may not represent every service location or current practice arrangement.
• Providers are counted once, by their primary taxonomy code only.
