This provider holds licence 112288-030 issued in WI. A licence number in NPPES reflects what was filed at registration — it does not confirm the licence is still active today.

What Registered Nurse covers
(1) A registered nurse is a person qualified by graduation from an accredited nursing school (depending upon schooling, a registered nurse may receive either a diploma from a hospital program, an associate degree in nursing (A.D.N.) or a Bachelor of Science degree in nursing (B.S.N.), who is licensed or certified by the state, and is practicing within the scope of that license or certification. R.N.'s assist patient in recovering and maintaining their physical or mental health. They assist physicians during treatments and examinations and administer medications. (2) A provider who is trained and educated in a formal nursing education program at an accredited school of nursing, passes a national certification examination, and is licensed by the state to practice nursing. The individual provides nursing services to patients or clients in areas such as health promotion, disease prevention, acute and chronic care and restoration and maintenance of health across the life span.

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 | 0 | 0 | 3 | 1 | 4 | 7 | 5 | 1 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 0 | 3 | 2 | 4 | 5 | 5 | 2 |
Sum = 47 · next multiple of 10 = 50 · check digit = 3 · actual last digit = 3
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.
