Credentials and Medicare
| Licence | State | Specialty |
|---|---|---|
| PT9298 | CA | Pediatric Physical Therapist primary |
This provider holds licence PT9298 issued in CA. A licence number in NPPES reflects what was filed at registration — it does not confirm the licence is still active today.
This NPI does not appear in the PECOS Medicare enrolment file. Providers who do not bill Medicare — or who bill only through a group's enrolment — will not appear here. It is not a sign of any problem with the registration.
What Pediatrics covers
A licensed physical therapist, including but not limited to an individual who is a Board Certified Specialist in Pediatric Physical Therapy, who has demonstrated specialized knowledge and skill in anatomy, histology, including embryonic development, genetics, biomechanics, neurological function, neuroscience, and pathology, behavioral sciences, and understanding of diseases or conditions that necessitate physical therapy care, that affect systems that in turn necessitate physical therapy care (comorbidities), and that influence the type of intervention that can be given. NUCC Health Care Provider Taxonomy, code 2251P0200X
The taxonomy records how the provider classifies their own practice. It does not confirm which conditions they currently treat, whether they are accepting new patients, or which insurance they take — call the office for that.
Full NPPES record
An NPI-1 identifies a single person. It stays with the clinician for life, even if they move practice or change state, which is why the address on file can lag behind where they actually work today.

Number check
How the check works, step by step
Every NPI carries a Luhn check digit — the same scheme used on credit cards. CMS prefixes the number with 80840 before computing it, which marks it as a US health identifier.
| Digit | 8 | 0 | 8 | 4 | 0 | 1 | 0 | 4 | 3 | 7 | 4 | 6 | 8 | 0 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 8 | 3 | 5 | 4 | 3 | 8 | 0 |
Sum = 57 · next multiple of 10 = 60 · check digit = 3 · actual last digit = 3
A valid check digit only means the number is well-formed. It does not mean the provider is licensed, active, or in good standing — those are separate questions answered by the sections above.
