What the code means

A dermatologist is trained to diagnose and treat pediatric and adult patients with benign and malignant disorders of the skin, mouth, external genitalia, hair and nails, as well as a number of sexually transmitted diseases. The dermatologist has had additional training and experience in the diagnosis and treatment of skin cancers, melanomas, moles and other tumors of the skin, the management of contact dermatitis and other allergic and nonallergic skin disorders, and in the recognition of the skin manifestations of systemic (including internal malignancy) and infectious diseases. Dermatologists have special training in dermatopathology and in the surgical techniques used in dermatology. They also have expertise in the management of cosmetic disorders of the skin such as hair loss and scars and the skin changes associated with aging.

Where they are

Counted by practice location, not by mailing address or by licence state. A provider practising across a state line is counted where they practise.

Showing the 15 largest of 51 states with at least one.

Who registers under this code

15,895 of these are people and 6,663 are organisations, so 30% of the code is businesses rather than clinicians. Half of them had registered by 2008, and 2,510 registered in the last five years, 11% of the current population.

That is a slow-growing code, which usually means an established field replacing retirements rather than expanding.

Where the practices are

By practice-location city. City counts are noisier than state counts, because a large employer files one address for many providers.

What else they list

Providers whose primary code is Dermatology Physician most often carry these secondary taxonomies as well. This is the closest thing the registry has to a map of which specialties overlap in practice, and it is not published anywhere else.

Looking up a specific provider

These counts come from the monthly NPPES file. To check one provider, use their NPI: the lookup reads the live registry and shows whether the identifier is still active, which the monthly file cannot tell you about the last few weeks.
