CPT® Code 95905

Motor and/or sensory nerve conduction, using preconfigured electrode array(s), amplitude and latency/velocity study, each limb, includes F-wave study when performed, with interpretation and report

The CPT® Code 95905 refers to a specific type of nerve conduction study that assesses both motor and sensory nerve function using preconfigured electrode arrays. This procedure is essential for diagnosing and evaluating various nerve disorders, including conditions such as carpal tunnel syndrome, which is characterized by symptoms like numbness, tingling, and other abnormal sensations in the limbs. The use of automated systems in these studies allows for efficient testing of sensory and motor nerves, particularly in the wrist and foot regions, where the median, ulnar, peroneal, posterior tibial, and sural nerves are commonly evaluated. During the procedure, a preconfigured electrode array is affixed to the skin of the limb being tested, enabling the delivery of electrical pulses. The study measures the conduction time, which is the duration it takes for the muscle to contract in response to the electrical stimulus. Additionally, the amplitude, or strength of the nerve response, along with the speed of conduction, indicated by latency or velocity, is meticulously recorded. An F-wave study may also be included, which involves the assessment of small amplitude, long latency responses that occur when the motor nerve is maximally stimulated. This aspect of the study provides valuable insights into the functionality of the proximal segments of the nerve. Typically, multiple F-wave recordings are captured at each stimulus site, and the data can be processed on-site or transmitted to a remote computer for analysis. Ultimately, the physician interprets the results and compiles a comprehensive written report detailing the findings of the nerve conduction study.
