Credentials and Medicare
NPPES does not list a state licence number for this record. That is not unusual — organizations and some provider types are not required to file one. Verify current licensure with the relevant state board before care.
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 Case Manager/Care Coordinator covers
A person who provides case management services and assists an individual in gaining access to needed medical, social, educational, and/or other services. The person has the ability to provide an assessment and review of completed plan of care on a periodic basis. This person is also able to take collaborative action to coordinate the services with other providers and monitor the enrollee's progress toward the cost-effective achievement of objectives specified in the plan of care. Credentials may vary from an experience in the fields of psychology, social work, rehabilitation, nursing or a closely related human service field, to a related Assoc of Arts Degree or to nursing credentials. Some states may require certification in case management. NUCC Health Care Provider Taxonomy, code 171M00000X

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 | 0 | 0 | 3 | 3 | 2 | 4 | 6 | 9 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 0 | 3 | 6 | 2 | 8 | 6 | 9 |
Sum = 60 · next multiple of 10 = 60 · check digit = 0 · actual last digit = 0
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.
