What Neurocritical Care covers
The medical subspecialty of Neurocritical Care is devoted to the comprehensive, multisystem care of the critically-ill neurological patient. Like other intensivists, the neurointensivist generally assumes the primary role for coordinating the care of his or her patients in the ICU, both the neurological and medical management of the patient. They may also provide consultative services for these patients as requested within the health system. NUCC Health Care Provider Taxonomy, code 2084A2900X

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 | 6 | 2 | 9 | 4 | 5 | 8 | 1 | 9 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 6 | 4 | 9 | 8 | 5 | 7 | 1 | 9 |
Sum = 75 · next multiple of 10 = 80 · check digit = 5 · actual last digit = 5
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.
