What Rehabilitation covers
Rehabilitation is the discipline focused on restoring a patient's functional abilities to pre-injury or pre-disease status. Functional abilities are defined as those activities in one's daily life, work, or sports and recreational activities that an individual participates in. Relevant impairments (e.g. strength, endurance, flexibility, motor control, etc.) are often intermediate goals of rehabilitation, but the final goal of successful care is return to participation in activities in which the patient was successful before the onset of the injury or disease. Essential to a rehabilitation approach is a focus on patient-centered outcomes such as independence and self-management or self-care skills. NUCC Health Care Provider Taxonomy, code 111NR0400X

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.

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 | 4 | 1 | 7 | 0 | 3 | 2 | 0 | 6 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 4 | 2 | 7 | 0 | 3 | 4 | 0 | 3 |
Sum = 49 · next multiple of 10 = 50 · check digit = 1 · actual last digit = 1
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.
