What Anesthesiologist Assistant covers
An individual certified by the state to perform anesthesia services under the direct supervision of an anesthesiologist. Anesthesiologist Assistants are required to have a bachelor's degree with a premed curriculum prior to entering a two-year anesthesiology assistant program, which is focused upon the delivery and maintenance of anesthesia care as well as advanced patient monitoring techniques. An Anesthesiologist Assistant must work as a member of the anesthesia care team under the direction of a qualified Anesthesiologist. NUCC Health Care Provider Taxonomy, code 367H00000X
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-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 | 8 | 9 | 1 | 3 | 4 | 3 | 1 | 7 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 8 | 9 | 1 | 6 | 4 | 6 | 1 | 5 |
Sum = 66 · next multiple of 10 = 70 · 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.
