What Rehabilitation covers
A psychologist who specializes in the study and application of psychological principles on behalf of persons who have disability due to injury or illness. Rehabilitation psychologists, often within teams, assess and treat cognitive, emotional, and functional difficulties, and help people to overcome barriers to participation in life activities. Rehabilitation psychologists are involved in practice, research, and advocacy, with the broad goal of fostering independence and opportunity for people with disabilities.

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 | 5 | 5 | 8 | 7 | 6 | 2 | 5 | 7 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 5 | 1 | 8 | 5 | 6 | 4 | 5 | 5 |
Sum = 65 · next multiple of 10 = 70 · check digit = 5 · actual last digit = 5
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.
