Definition

Where 2084N0600X sits

Choose 2084N0600X over the general Psychiatry & Neurology code when the provider's training or certification is specifically in clinical neurophysiology; the general code covers the classification as a whole. A provider may report more than one taxonomy code on an NPI but marks one as primary.

Medicare

CMS's taxonomy crosswalk links 2084N0600X to Medicare specialty 86 (Physician/Neuropsychiatry). That specialty — not the taxonomy code itself — is what Medicare enrollment records and uses for payment. 436 practitioners are enrolled under it nationally, and 19 other taxonomy codes map to the same specialty.

Other codes under the same Medicare specialty: 2084A0401X Addiction Medicine (Psychiatry & Neurology) Physician; 2084B0002X Obesity Medicine (Psychiatry & Neurology) Physician; 2084B0040X Behavioral Neurology & Neuropsychiatry Physician; 2084D0003X Diagnostic Neuroimaging (Psychiatry & Neurology) Physician; 2084F0202X Forensic Psychiatry Physician; 2084H0002X Hospice and Palliative Medicine (Psychiatry & Neurology) Physician; 2084N0008X Neuromuscular Medicine (Psychiatry & Neurology) Physician; 2084N0400X Neurology Physician; and 11 more.

Using 2084N0600X

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.
