NERVE CONDUCTION STUDY GUIEDLINE
 Most patients are referred for NCS testing with a provisional diagnosis; patients are referred with merely symptoms and/or clinical
findings with the expectation that the neurologist will be able to arrive at the correct diagnosis only after the completion of the NCS.
When “rule-out” diagnoses are not accepted, only a symptomatic diagnosis (“pain in limb” or “neuralgia and neuritis”) can be coded
regardless of the work involved in performing the evaluation for the working diagnosis/provisional diagnosis. Furthermore, NCS testing
does not always establish an etiologic diagnosis and may modify the referral diagnosis.
 A typical NCS examination documentation should include development of a differential diagnosis by the physician based upon
appropriate history and physical examination when an etiologic diagnosis is not established.
 A final diagnosis can be coded if an established diagnosis is established after the completion of the NCS testing with the final
interpretation of the study is a synthesis by the neurologist of the patient’s history, physical examination, and the preceding and
following portions of the study.
