What Gerontology covers
Occupational therapists work with older adults in virtually every setting: assisted living, wellness programs, hospitals, nursing homes, senior centers, clinics and in the home. Occupational therapists bring an understanding of the importance of participation and occupation for overall well-being to those who are experiencing disabling conditions related to aging. The primary overarching goal of occupational therapy services with this population is to maximize independence and participation, thereby enabling an older person to continue to live successfully in his or her chosen environment. Occupational therapists can help older adults by developing strategies to help or maintain safety and well-being, to assist with life transitions, and to compensate for challenges they experience in activities of daily living, instrumental activities of daily living, leisure participation, social participation, and productive activities. NUCC Health Care Provider Taxonomy, code 225XG0600X
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 | 0 | 0 | 3 | 2 | 7 | 3 | 6 | 2 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 0 | 3 | 4 | 7 | 6 | 6 | 4 |
Sum = 56 · next multiple of 10 = 60 · 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.
