What Diagnostic Neuroimaging covers
A licensed physician, who has completed a residency program in Neurology, and who has additional training, experience, and competence in the standards of performance and interpretation of Magnetic Resonance Imaging (MRI / MRA) of the head, spine, and peripheral nerves, and Computed Tomography (CT) of the head and spine. Physicians are trained in the administration of contrast media and the recognition and treatment of adverse reactions to contrast media. Neuroimaging training encompasses thorough knowledge of clinical neurology, neurophysiology, neuroanatomy, neurochemistry, neuropharmacology, and dynamics of cerebrospinal fluid circulation. Physicians possess special expertise in the technical aspects and clinical applications of each of the modalities and techniques of neuroimaging. NUCC Health Care Provider Taxonomy, code 2085D0003X
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 | 2 | 7 | 5 | 8 | 3 | 5 | 6 | 4 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 2 | 5 | 5 | 7 | 3 | 1 | 6 | 8 |
Sum = 63 · next multiple of 10 = 70 · 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.
