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 organization, so it may cover several clinicians at this location. 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. Speech-language pathologists (SLPs) evaluate and treat speech sounds, language, stuttering, voice, and feeding and swallowing. Ask whether the clinic treats children and which ages.

Checking a license: the number above is what the provider entered in the NPI registry. Your state licensing board's lookup shows whether it is current. For individual therapists, ASHA (speech) and NBCOT (occupational therapy) let you verify national certification.
