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. Audiologist-Hearing Aid Fitter is a single NPPES category that covers both audiologists and hearing aid fitters; the credentials and license show which applies.
