CPT® Code 95913

Nerve conduction studies (NCS) are diagnostic tests utilized to assess the functionality of peripheral nerves. These studies are particularly important for identifying nerve damage and various nerve disorders, including conditions such as carpal tunnel syndrome. Patients may present with symptoms like numbness, tingling, or other abnormal sensations, which can indicate underlying nerve issues. During the procedure, several flat metal disc electrodes are affixed to the skin using adhesive paste or tape. A shock-emitting electrode is strategically placed over the nerve being evaluated, while a recording electrode is positioned over the muscles that the nerve innervates. The process involves sending electrical pulses through the shock-emitting electrode, which stimulates the nerve. The conduction time is measured, reflecting the duration it takes for the muscle to contract in response to the electrical stimulus. Additionally, the amplitude, or strength of the muscle response, along with the speed of the response, indicated by latency or velocity, is recorded. After the completion of the studies, the physician analyzes the collected data and generates a comprehensive written report detailing the findings. For coding purposes, specific CPT® codes are designated for varying numbers of nerve conduction studies, with CPT® Code 95913 specifically representing 13 or more studies.
