What Neuro-ophthalmology covers
A neuro-ophthalmologist is a subspecialist of ophthalmology. This physician evaluates, treats, and studies disorders of the eye, orbit and nervous system having to do with interactions of the visual motor and visual sensory systems with the central nervous system. Neuro-ophthalmologists manage patients with complex and severe neuro-ophthalmological disorders. NUCC Health Care Provider Taxonomy, code 207WX0109X

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 | 6 | 9 | 4 | 4 | 2 | 6 | 8 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 6 | 3 | 9 | 8 | 4 | 4 | 6 | 7 |
Sum = 73 · next multiple of 10 = 80 · check digit = 7 · actual last digit = 7
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.
