Definition
A physician who specializes in neuromuscular medicine possesses specialized knowledge in the science, clinical evaluation and management of these disorders. This encompasses the knowledge of the pathology, diagnosis and treatment of these disorders at a level that is significantly beyond the training and knowledge expected of a general neurologist, child neurologist or physiatrist.

Using 2081N0008X
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.
