Determining the proper number of units for nerve conductions has always been a challenge. The AANEM worked with the American Medical Association (AMA) and the American Academy of Neurology (AAN) to create a list of nerves to assist physicians and billing departments to clarify the specific nerves that can be billed for nerve conduction studies. Each study on the list qualifies as one unit for nerve conduction studies (95900, 95903 and 95904).
