About this list

The NPI Registry is the U.S. government's public register of clinicians, run by CMS. Where a doctor's own practice or hospital page lists training, languages or focus areas, we add them with a link to that page. Pori does not rank, rate or endorse anyone here and is paid by no one to list them. Call the practice to check it takes new patients and your insurance. Is this your listing? Update it in NPPES and it changes here at our next refresh, or email hello@getpori.app to correct or remove it.

What is Mohs surgery?

It is used mostly for basal and squamous cell carcinoma on the face, ears, hands and other places where tissue matters.

Usually the cancer is first diagnosed by biopsy, often by a general dermatologist, who then refers you. Many insurance plans also require a referral. Call the practice to check.

Is every dermatologist a Mohs surgeon?
