Nerve conduction studies; 13 or more studies.
Modifiers 26 (Professional Component), 52 (Reduced Services), 53 (Discontinued Procedure), and other relevant modifiers may be applicable depending on the specific circumstances of the service.
Medical necessity for nerve conduction studies must be supported by documentation of signs, symptoms, or conditions that suggest the presence of a nerve disorder or injury. The nerve conduction studies must be necessary for diagnosis or treatment planning.
The physician or other qualified healthcare professional is responsible for performing and interpreting the nerve conduction studies. This includes proper electrode placement, real-time waveform review and adjustments, and report preparation including analysis of waveform characteristics and nerve conduction velocities, and providing a diagnosis and treatment plan based on the findings.
In simple words: This test measures how well and how fast electrical signals travel through your nerves. It helps figure out if there's any nerve damage. Small pads are placed on your skin, some of which give off tiny, safe electrical pulses, and others record how your nerves react. This is done for at least 13 different nerves. The results help your doctor understand where and how your nerves might be affected.
This code represents nerve conduction studies performed with individually placed stimulating, recording, and ground electrodes on 13 or more nerves. The placement of electrodes and the test design must be tailored to the patient's anatomy. The nerves tested are limited to those required for the specific clinical question. The stimulating electrode is placed directly over the nerve being tested, with parameters adjusted to avoid stimulating other nerves or branches. Motor nerve conduction studies typically involve both proximal and distal stimulation. Recordings are made from electrodes placed directly over the motor point of the muscle being tested for motor nerves, and directly over the nerve being tested for sensory nerves. Waveforms are reviewed in real time, and adjustments are made to minimize artifact and unintended stimulation or recording. Reports are prepared on-site, interpreting the amplitude, latency, and configuration of waveforms, calculating nerve conduction velocities, and providing a physician's interpretation.
Example 1: A patient presents with numbness and tingling in the hands and feet. To evaluate for peripheral neuropathy, nerve conduction studies are performed on multiple nerves in the upper and lower extremities., A patient with suspected carpal tunnel syndrome undergoes nerve conduction studies of the median nerve across the wrist to assess for entrapment., Following a traumatic injury to the arm, nerve conduction studies are performed to evaluate the extent of nerve damage and guide treatment decisions.
Documentation should include the reason for the study, the nerves tested, the findings (latency, amplitude, conduction velocity), interpretation of the findings, and diagnosis. A detailed description of the patient’s symptoms, relevant medical history, and physical examination findings should also be documented.
