This provider holds licence C39057 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 Psychiatric Residential Treatment Facility covers
A residential treatment facility (RTF) is a facility or distinct part of a facility that provides to children and adolescents, a total, twenty-four hour, therapeutically planned group living and learning situation where distinct and individualized psychotherapeutic interventions can take place. Residential treatment is a specific level of care to be differentiated from acute, intermediate, and long-term hospital care, when the least restrictive environment is maintained to allow for normalization of the patient's surroundings. The RTF must be both physically and programmatically distinct if it is a part or subunit of a larger treatment program. An RTF is organized and professionally staffed to provide residential treatment of mental disorders to children and adolescents who have sufficient intellectual potential to respond to active treatment (that is, for whom it can reasonably be assumed that treatment of the mental disorder will result in an improved ability to function outside the RTF) for whom outpatient treatment, partial hospitalization or protected and structured environment is medically or psychologically necessary NUCC Health Care Provider Taxonomy, code 323P00000X

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 | 4 | 5 | 7 | 5 | 4 | 3 | 8 | 9 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 4 | 1 | 7 | 1 | 4 | 6 | 8 | 9 |
Sum = 66 · next multiple of 10 = 70 · 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.
