CPT® Code 95863

Needle electromyography (EMG) is a specialized diagnostic procedure utilized to assess and diagnose various neuromuscular disorders. This test is particularly effective in evaluating symptoms such as pain, weakness, numbness, or tingling sensations that may occur in the upper or lower extremities. During the procedure, the electrical activity of muscles is recorded, providing valuable insights into the health and functionality of the neuromuscular system. Abnormalities in the electrical activity can indicate a range of underlying conditions, including but not limited to muscle inflammation, nerve compression, intervertebral disc herniation, peripheral nerve injuries, muscular dystrophies, amyotrophic lateral sclerosis (ALS), and myasthenia gravis. The process involves the insertion of one or more fine needle electrodes through the skin and into the muscle tissue. These electrodes are connected to a recording device that visually displays the electrical activity of the muscle. To obtain comprehensive data, patients may be instructed to move the affected extremity, allowing for recordings of muscle activity during both flexion and extension. The response of muscle fibers to nerve stimulation, known as action potential, is graphically represented as waveforms on the display. This procedure also encompasses EMG recordings from related paraspinal areas, enhancing the diagnostic capability of the test. Following the completion of the EMG, the physician meticulously reviews the recorded data and generates a detailed written report summarizing the findings. For coding purposes, specific CPT® codes are designated for different numbers of extremities assessed: 95860 for one extremity, 95861 for two extremities, 95863 for three extremities, and 95864 for four extremities.
