What Epilepsy covers
Epilepsy is a subspecialty of neurology focused on the diagnosis and treatment of patients with epilepsy, including new-onset, medically refractory epilepsy, psychogenic nonepileptic seizures, and epilepsy in special populations (the elderly, women, patients with co-morbidities). Epilepsy is a multidisciplinary field that provides comprehensive care of the patient.<br/> NUCC Health Care Provider Taxonomy, code 2084E0001X

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 | 9 | 8 | 2 | 4 | 0 | 4 | 4 | 4 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 9 | 7 | 2 | 8 | 0 | 8 | 4 | 8 |
Sum = 72 · next multiple of 10 = 80 · check digit = 8 · actual last digit = 8
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.
