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. Pediatric occupational therapists help children with fine motor skills, self-care, sensory processing, handwriting and feeding.

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.
