Credentials and Medicare
| Licence | State | Specialty |
|---|---|---|
| 1919683 | IL | In Home Supportive Care Agency primary |
This provider holds licence 1919683 issued in IL. A licence number in NPPES reflects what was filed at registration — it does not confirm the licence is still active today.
This NPI does not appear in the PECOS Medicare enrolment file. Providers who do not bill Medicare — or who bill only through a group's enrolment — will not appear here. It is not a sign of any problem with the registration.
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. NUCC Health Care Provider Taxonomy, code 253Z00000X
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-2 identifies an organization — a clinic, hospital, group practice, laboratory, or supplier. Individual clinicians working there hold their own NPI-1 numbers separately, so a bill may reference both.

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 | 0 | 4 | 3 | 2 | 9 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 0 | 3 | 0 | 4 | 6 | 2 | 9 |
Sum = 50 · next multiple of 10 = 50 · 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.
