Credentials and Medicare
| Licence | State | Specialty |
|---|---|---|
| 200736110057 | CA | Portable X-ray and/or Other Portable… primary |
This provider holds licence 200736110057 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 Portable X-ray and/or Other Portable Diagnostic Imaging Supplier covers
A supplier that provides one or more of the following portable services, including but not limited to, x-ray, electrocardiogram (EKG), long-term EKG (Holter Monitor), bone densitometry, sonography, and other imaging services in accordance with all state and federal requirements, under the general supervision of a qualified physician. All necessary resources are transported to the patient's location where the services are performed. NUCC Health Care Provider Taxonomy, code 335V00000X
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-2 identifies an organization — a clinic, hospital, group practice, laboratory, or supplier. Individual clinicians working there hold their own NPI-1 numbers separately, so a bill may reference both.

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 | 8 | 3 | 1 | 3 | 7 | 3 | 6 | 8 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 8 | 6 | 1 | 6 | 7 | 6 | 6 | 7 |
Sum = 73 · next multiple of 10 = 80 · 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.
