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 Driving and Community Mobility covers
Occupational therapy assistants contribute to the completion of an individualized occupational therapy driving and community mobility evaluation by administering delegated assessments and identifying findings that impact the client's occupational performance. Clients engage in the assessment and occupational profile process to customize the evaluation to their individual driving and community mobility needs. Occupational therapy assistants administer and continuously modify individualized in-vehicle and community mobility assessments within the naturalistic context of the community in response to the occupational performance and safety behaviors of the client. They also implement an individualized intervention plan, within the parameters established in collaboration with the occupational therapist that reflects the contexts of the client and meets his or her occupational performance and safety needs. Occupational therapy assistants address immediate and long-term implications of psychosocial issues related to compromised driving and community mobility throughout the occupational therapy process and makes recommendations to the occupational therapist for modification to service delivery. NUCC Health Care Provider Taxonomy, code 224ZR0403X
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-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 | 1 | 6 | 4 | 3 | 1 | 0 | 5 | 7 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 1 | 3 | 4 | 6 | 1 | 0 | 5 | 5 |
Sum = 51 · next multiple of 10 = 60 · check digit = 9 · actual last digit = 9
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.
