What Surgical Assistant covers
A surgical assistant is a skilled practitioner who has undergone formalized education and training as a surgical assistant. The surgical assistant performs surgical functions that include, but are not limited to: retracting, manipulating, suturing, clamping, cauterizing, litigating, and tying tissue; suctioning, irrigating and sponging; positioning the patient; closure of body planes and skin; and participating in hemostasis and volume replacement. Surgical assistants are certified and registered or licensed by the state, or, in states without licensure, certified as surgical assistants by completing appropriate education and training.

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 | 0 | 0 | 3 | 0 | 4 | 7 | 7 | 7 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 0 | 3 | 0 | 4 | 5 | 7 | 5 |
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.
