How we verify
Dermatologist Index is compiled from public records, not from who paid to be listed.
Sources
- NPPES NPI Registry (CMS) — The federal registry of National Provider Identifiers; the monthly bulk file and weekly updates are our main source.
- CMS Doctors and Clinicians (Provider Data Catalog) — Medicare-enrolled clinicians with their group practice, group size, Medicare assignment, telehealth indicator and graduation year.
- American Board of Dermatology — Where to verify board certification in dermatology (MD and DO).
- American Osteopathic Board of Dermatology — Certifying board for osteopathic dermatologists.
- DocInfo (Federation of State Medical Boards) — Physician license and disciplinary information across states.
We read the NPPES monthly bulk file, plus CMS's weekly updates, and keep active NPIs whose primary taxonomy is Dermatology (207N00000X) or one of its patient-facing subspecialties: MOHS-Micrographic Surgery (207ND0101X), Procedural Dermatology (207NS0135X) and Pediatric Dermatology (207NP0225X), in the United States and its territories. Dermatopathology, a laboratory specialty, is left out.
Records whose NPI was last updated before 2013 are left out as dormant (those providers have mostly retired or moved), unless CMS's current Doctors & Clinicians file lists the clinician, or a group with the same name at the same ZIP, as enrolled in Medicare. Organizations with the same name, address and ZIP are merged.
Medicare facts come from CMS's Doctors & Clinicians national file: individual clinicians are matched exactly by NPI; organizations are matched to a CMS group with the same legal name at the same ZIP. Assignment means the clinician or group accepts the Medicare-approved amount as payment in full (CMS marks some as may accept). Telehealth means Medicare claims show telehealth services. A listing without Medicare facts is simply not matched; it does not mean the provider is out of network or refuses Medicare.
The specialty in NPPES is self-reported. We show it as Registered specialty and never as board certification. A license number on a record is what the provider entered; we do not verify it. Other practice locations come from the NPPES monthly file. The "Cosmetic and laser" group is based only on the words in a practice's registered name.
We do not publish ratings, reviews, prices or outcomes. Order within a city: practices first, then listings CMS shows as Medicare-enrolled, then the most recently updated NPI records, then alphabetical. This is not a ranking of quality. Featured listings appear in a separate, labelled box and never change that order.
What a badge means
NPI active: the federal NPPES registry lists an active NPI with Dermatology (or a dermatology subspecialty) as the registered specialty. The specialty is self-reported, so this is not board certification or a license check. We only publish positive matches. A listing without a badge is not an accusation — most gaps are name variations between registries.
Freshness
Data was last refreshed on 2026-10-16. CMS publishes the full NPPES file every month and weekly update files in between; we apply both every week, and re-read CMS's Doctors & Clinicians file, so listings are at most about a week behind, and every page shows the date of the data.
