What Driving and Community Mobility covers
Occupational therapists can optimize and prolong an older driver's ability to drive safely and ease the transition to other forms of transportation if driving cessation becomes necessary. By identifying strengths as well as physical or cognitive challenges, occupational therapists can evaluate an individual's overall ability to operate a vehicle safely and recommend assistive devices or behavioral changes to limit risks. Occupational therapy practitioners offer a continuum of services related to community mobility, from evaluation of driving performance, through counseling and support for lifestyle changes, to maintaining independence and quality of life.

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 | 7 | 2 | 0 | 1 | 4 | 8 | 7 | 5 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 7 | 4 | 0 | 2 | 4 | 7 | 7 | 1 |
Sum = 58 · next multiple of 10 = 60 · check digit = 2 · actual last digit = 2
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.
