Credentials and Medicare
| Licence | State | Specialty |
|---|---|---|
| 28889 | AZ | Psychiatry Physician |
| 28889 | AZ | Community/Behavioral Health Agency primary |
This provider holds licence 28889 issued in AZ. 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 Community/Behavioral Health covers
A private or public agency usually under local government jurisdiction, responsible for assuring the delivery of community based mental health, intellectual disabilities, substance abuse and/or behavioral health services to individuals with those disabilities. Services may range from companion care, respite, transportation, community integration, crisis intervention and stabilization, supported employment, day support, prevocational services, residential support, therapeutic and supportive consultation, environmental modifications, intensive in-home therapy and day treatment, in addition to traditional mental health and behavioral treatment.

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 | 5 | 1 | 8 | 0 | 9 | 6 | 2 | 8 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 5 | 2 | 8 | 0 | 9 | 3 | 2 | 7 |
Sum = 62 · next multiple of 10 = 70 · check digit = 8 · actual last digit = 8
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.
