Credentials and Medicare
| Licence | State | Specialty |
|---|---|---|
| 40QA01307200 | NJ | Orthopedic Physical Therapist primary |
This provider holds licence 40QA01307200 issued in NJ. 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 Orthopedic covers
A licensed physical therapist, including but not limited to an individual who is a Board Certified Specialist in Orthopaedic Physical Therapy, who has demonstrated specialized knowledge and skill in human anatomy and physiology, movement science; pathology/pathophysiology, pain science, medical and surgical considerations, orthopaedic physical therapy theory and practice, and critical inquiry for evidence-based practice. NUCC Health Care Provider Taxonomy, code 2251X0800X
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 | 1 | 2 | 4 | 0 | 8 | 6 | 6 | 5 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 1 | 4 | 4 | 0 | 8 | 3 | 6 | 1 |
Sum = 53 · next multiple of 10 = 60 · check digit = 7 · actual last digit = 7
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.
