What Physical Rehabilitation covers

Occupational therapists are experts at helping people lead as independent a life as possible. Occupational therapists bring an understanding of the physical and psychological implications of illness and injury and their effects on peoples' ability to perform the tasks of daily living. Occupational therapists provide interventions that can aide a person in completing ADL and IADL tasks, such as dressing, bathing, preparing meals, and driving. They also may fabricate custom orthotics to improve function, evaluate the environment for safety hazards and recommend adaptations to remove those hazards, help a person compensate for cognitive changes, and build a persons' physical endurance and strength. Occupational therapists' knowledge of adapting tasks and modifying the environment to compensate for functional limitations is used to increase the involvement of clients and to promote safety and success.

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

1821687989 passes the NPI check digit test The final digit 9 matches the value computed from the first nine digits, so this is a well-formed NPI.
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 8 2 1 6 8 7 9 8
Doubled? ×2 ×2 ×2 ×2 ×2 ×2 ×2
Value 8 0 8 8 0 2 8 4 1 3 8 5 9 7

Sum = 71 · next multiple of 10 = 80 · 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.
