This provider holds licence AU407 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 Audiologist-Hearing Aid Fitter covers
An audiologist/hearing aid fitter is the professional who specializes in evaluating and treating people with hearing loss, conducts a wide variety of tests to determine the exact nature of an individual's hearing problem, presents a variety of treatment options to patients, dispenses and fits hearing aids, administers tests of balance to evaluate dizziness and provides hearing rehabilitation training. This classification should be used where individuals are licensed as "audiologist-hearing aid fitters" as opposed to states that license individuals as "audiologists".

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.

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 | 4 | 0 | 7 | 9 | 8 | 1 | 1 | 2 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 4 | 0 | 7 | 9 | 8 | 2 | 1 | 4 |
Sum = 61 · next multiple of 10 = 70 · check digit = 9 · actual last digit = 9
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.
