Credentials and Medicare
| Licence | State | Specialty |

Enrolled in Medicare 2 times, across 1 state:
| State | Enrollment ID | Provider type |
|---|---|---|
| District of Columbia | O20080930000810 | Part B Supplier - Clinic/group Practice |
| District of Columbia | O20241227001807 | Part B Supplier - Clinic/group Practice |
Medicare enrolment is recorded as approved under the provider type Part B Supplier - Clinic/group Practice. There are 2 separate enrolment records. Multiple enrolments usually mean the provider bills Medicare from more than one practice location, or has kept an earlier enrolment after moving. Each record carries its own enrolment ID, listed above. Being enrolled means the provider can bill Medicare; it does not tell you whether they are currently accepting new Medicare patients. Call the office to confirm.
What Audiologist covers
(1) A specialist in evaluation, habilitation and rehabilitation of those whose communication disorders center in whole or in part in hearing function. Audiologists are autonomous professionals who identify, assess, and manage disorders of the auditory, balance and other neural systems. Audiologists provide audiological (aural) rehabilitation to children and adults across the entire age span. Audiologists select, fit and dispense amplification systems such as hearing aids and related devices. (2) An audiologist is a person qualified by a master's degree in audiology, licensed by the state, where applicable, and practicing within the scope of that license. Audiologists evaluate and treat patients with impaired hearing. They plan, direct and conduct rehabilitative programs with audiotry substitutional devises (hearing aids) and other therapy. NUCC Health Care Provider Taxonomy, code 231H00000X
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 | 0 | 0 | 3 | 0 | 1 | 0 | 4 | 8 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 0 | 3 | 0 | 1 | 0 | 4 | 7 |
Sum = 41 · next multiple of 10 = 50 · 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.
