What Trauma Surgery covers
Trauma surgery is a recognized subspecialty of general surgery. Trauma surgeons are physicians who have completed a five-year general surgery residency and usually continue with a one to two year fellowship in trauma and/or surgical critical care, typically leading to additional board certification in surgical critical care. There is no trauma surgery board certification at this point. To obtain board certification in surgical critical care, a fellowship in surgical critical care or anesthesiology critical care must be completed during or after general surgery residency.

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 | 4 | 2 | 7 | 0 | 3 | 5 | 5 | 3 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 4 | 4 | 7 | 0 | 3 | 1 | 5 | 6 |
Sum = 56 · next multiple of 10 = 60 · check digit = 4 · actual last digit = 4
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.
