Credentials and Medicare

State licence

Licences are recorded in 2 states: OR, MA. Providers licensed in several states often practise near a state border or deliver telehealth across state lines.

Medicare (PECOS)
Status

Enrolled in Medicare 2 times, across 2 states:

StateEnrollment IDProvider type
Oregon I20220804001518 Practitioner - Psychiatry
North Carolina I20241021000216 Practitioner - Psychiatry

Medicare enrolment is recorded as approved under the provider type Practitioner - Psychiatry. There are 2 separate enrolment records across 2 states (OR, NC). 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.

Licensed in 2 states

This provider holds licences in 2 states: Massachusetts and Oregon. The practice address on file is in Portland, OR, but a licence in another state usually means they see patients there too — either at a second location or by telehealth. If the address above is far from you, it is worth calling to ask whether they practise closer to where you live.

What Psychiatry covers

A Psychiatrist specializes in the prevention, diagnosis, and treatment of mental disorders, emotional disorders, psychotic disorders, mood disorders, anxiety disorders, substance-related disorders, sexual and gender identity disorders and adjustment disorders. Biologic, psychological, and social components of illnesses are explored and understood in treatment of the whole person. Tools used may include diagnostic laboratory tests, prescribed medications, evaluation and treatment of psychological and interpersonal problems with individuals and families, and intervention for coping with stress, crises, and other problems.

All registered taxonomy codes

This provider registers 2 taxonomy codes. The primary code is what appears on most claims; the others record additional recognised specialties.

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

1003157504 passes the NPI check digit test The final digit 4 matches the value computed from the first nine digits, so this is a well-formed NPI.
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 1 5 7 5 0
Doubled? — ×2 — ×2 — ×2 — ×2 — ×2 — ×2 — ×2
Value 8 0 8 8 0 2 0 0 3 2 5 5 5 0

Sum = 46 · next multiple of 10 = 50 · check digit = 4 · actual last digit = 4

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.
