Definition
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.

Medicare
CMS's taxonomy crosswalk links 2085D0003X to Medicare specialty 30 (Physician/Diagnostic Radiology). That specialty — not the taxonomy code itself — is what Medicare enrollment records and uses for payment. 38,230 practitioners are enrolled under it nationally, and 4 other taxonomy codes map to the same specialty.
Other codes under the same Medicare specialty: 2085P0229X Pediatric Radiology Physician; 2085R0202X Diagnostic Radiology Physician; 2085R0205X Radiological Physics Physician; 2085U0001X Diagnostic Ultrasound Physician.

Using 2085D0003X
The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
