What Geriatrics covers
A licensed physical therapist, including but not limited to an individual who is a Board Certified Specialist in Geriatric Physical Therapy, who has demonstrated specialized knowledge and skill in the comprehensive biopsychosocial assessment and evidence-based management of movement in aging adults. This includes, but is not limited to, specialized knowledge in and consideration of normal age-related changes and pathological manifestations across all systems; cognition and mental health; polypharmacy; fall risk mitigation; bone health; healthy and active aging, and socioeconomic and health policy issues affecting aging adults. The geriatric physical therapist is an integral part of the interdisciplinary geriatric team and serves as an advocate for the highest level of well-being for the older adult.

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 | 6 | 2 | 5 | 7 | 1 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 0 | 3 | 3 | 2 | 1 | 7 | 2 |
Sum = 44 · next multiple of 10 = 50 · check digit = 6 · actual last digit = 6
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.
