Add-On Code

Needle electromyography, non-extremity (cranial nerve supplied or axial) muscle(s) done with nerve conduction, amplitude and latency/velocity study (List separately in addition to code for primary procedure)

Needle electromyography (EMG) is a specialized diagnostic procedure utilized to assess the electrical activity of muscles, particularly in cases where patients experience symptoms such as pain, weakness, numbness, or tingling. This procedure is particularly focused on non-extremity muscles, which include those supplied by cranial nerves or located in the axial region of the body. During the needle EMG, one or more fine needle electrodes are inserted through the skin and into the muscle tissue to record the electrical signals generated by muscle fibers. This process allows for the evaluation of the muscle's response to nerve stimulation, which is crucial for diagnosing various neuromuscular disorders. In conjunction with needle EMG, nerve conduction studies are often performed to provide a comprehensive assessment of nerve function. These studies involve the use of flat metal disc electrodes placed on the skin to measure the speed and strength of electrical signals traveling through the nerves. By applying electrical pulses to the nerve, the conduction time—the duration it takes for the muscle to contract in response to the stimulation—is recorded. Additionally, the amplitude, which reflects the strength of the muscle's response, as well as latency and velocity measurements, are captured to evaluate nerve integrity and function. The results from both the needle EMG and nerve conduction studies are analyzed by the physician, who then compiles a detailed report of the findings. The CPT® Code 95887 is specifically used when these diagnostic tests are performed alongside another separately reportable neuromuscular procedure.
