Credentials and Medicare
| Licence | State | Specialty |
|---|---|---|
| 50710 | CA | Pharmacist primary |
This provider holds licence 50710 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 Pharmacist covers
An individual licensed by the appropriate state regulatory agency to engage in the practice of pharmacy. The practice of pharmacy includes, but is not limited to, assessment, interpretation, evaluation, and implementation, initiation, monitoring or modification of medication and or medical orders; the compounding or dispensing of medication and or medical orders; participation in drug and device procurement, storage, and selection; drug administration; drug regimen reviews; drug or drug-related research; provision of patient education and the provision of those acts or services necessary to provide medication therapy management services in all areas of patient care. NUCC Health Care Provider Taxonomy, code 183500000X
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 | 0 | 3 | 3 | 5 | 3 | 2 | 3 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 0 | 3 | 6 | 5 | 6 | 2 | 6 |
Sum = 54 · next multiple of 10 = 60 · check digit = 6 · actual last digit = 6
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.
