What Midwife covers
A Midwife is a trained professional with special expertise in supporting women to maintain a healthy pregnancy birth, offering expert individualized care, education, counseling, and support to a woman and her newborn throughout the childbearing cycle. A Midwife is a skilled and independent practitioner who has undergone formalized training. Midwives are not required to be nurses and may be trained via multiple routes of education (apprenticeship, workshop, formal classes, or programs, etc., usually a combination). The educational background requirements and licensing requirements vary by state. The Midwife may or may not be certified by a state or national organization.

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 | 2 | 5 | 5 | 0 | 4 | 1 | 7 | 2 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 2 | 1 | 5 | 0 | 4 | 2 | 7 | 4 |
Sum = 51 · next multiple of 10 = 60 · check digit = 9 · actual last digit = 9
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.
