What these registry facts mean

The NPI (National Provider Identifier) is the federal ID every HIPAA-covered provider uses to bill insurance. This NPI belongs to an individual clinician. The specialty is the taxonomy the provider chose when registering; NPPES does not check it. A license number here is what the provider entered — confirm it with the state board before you rely on it. Orthodontists are dentists who completed an accredited orthodontic residency after dental school. General dentists can also offer braces or aligners, but they are not listed here.

Checking credentials: the specialty shown is the one this provider registered with the NPI system. Your state dental board's license lookup confirms the license, and the American Board of Orthodontics lists board-certified orthodontists.
