Credentials and Medicare
| Licence | State | Specialty |
|---|---|---|
| 4650 | WA | Advanced Practice Dental Therapist primary |
This provider holds licence 4650 issued in WA. 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 Advanced Practice Dental Therapist covers
An Advanced Practice Dental Therapist is:<br/>(1) A dental therapist who has completed additional training beyond basic dental therapy education and provides dental services in accordance with state advanced practice dental therapist laws or statutes; or<br/>(2) A dental hygienist with a graduate degree in advanced dental therapy prepared for independent and interdependent decision making and direct accountability for clinical judgment across the dental health care continuum.<br/>The individual has been authorized by the relevant state board or a tribal entity to provide services under the remote supervision of a dentist. The functions of the advanced practice dental therapist vary based on the needs of the dentist, the educational preparation of the advanced practice dental therapist and state dental practice acts and regulations. NUCC Health Care Provider Taxonomy, code 125K00000X
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 | 2 | 6 | 9 | 4 | 7 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 0 | 3 | 4 | 6 | 9 | 4 | 5 |
Sum = 57 · next multiple of 10 = 60 · check digit = 3 · actual last digit = 3
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.
