What In Home Supportive Care covers
An In Home Supportive Care Agency provides services in the patient's home with the goal of enabling the patient to remain at home. The services provided may include personal care services such as hands-on assistance with activities of daily living (ADLs), e.g., eating, bathing, dressing, and bladder and bowel requirements; homemaker services and instrumental activities of daily living (IADLs), e.g., taking medications, shopping for groceries, laundry, housekeeping, and companionship; and/or supervision or cuing so that a person can perform tasks themselves.

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 | 9 | 9 | 2 | 2 | 6 | 5 | 5 | 4 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 9 | 9 | 2 | 4 | 6 | 1 | 5 | 8 |
Sum = 70 · next multiple of 10 = 70 · check digit = 0 · actual last digit = 0
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.
