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. Oral and maxillofacial surgeons are trained in surgery of the mouth and jaws, including placing implants, extractions, bone grafts and sinus lifts, and in anesthesia. Dentists who are not specialists can also place implants; the specialty here is the one the provider registered as primary.
