Nerve conduction studies (3-4 studies).
Modifiers 26 (Professional Component), 52 (Reduced Services), 53 (Discontinued Procedure), and others may be applicable depending on the specific circumstances of the service provided.
Medical necessity must be established for nerve conduction studies. Documentation should clearly link the test to the patient's symptoms, signs, and suspected diagnosis. The medical record should support the need for the study to evaluate and manage the patient's condition.
The physician or other qualified healthcare professional is responsible for the entire procedure, including electrode placement, stimulation parameter adjustment, real-time waveform analysis, interpretation of results, and report generation.
In simple words: This test checks how well your nerves can send electrical signals. It helps doctors find problems like nerve damage or pinched nerves. Small sensors are placed on your skin, and a mild electrical pulse is sent through the nerve. The test results show how fast and strong the signals travel, helping the doctor figure out what's wrong.
This code represents 3-4 distinct nerve conduction studies used to assess the function of motor and sensory nerves. A single study may be a sensory conduction test, a motor conduction test (with or without F-wave), or an H-reflex test. Multiple stimulations/recordings on the same nerve count as one study. Includes individualized electrode placement, real-time waveform review, and on-site report generation with interpretation by a physician or other qualified healthcare professional.
Example 1: A patient presents with numbness and tingling in their hand. To assess for carpal tunnel syndrome, the physician performs nerve conduction studies on the median nerve across multiple points in the wrist and forearm (one study). Additional studies are performed on the ulnar and radial nerves for comparison and to exclude other potential diagnoses., A patient experiences foot drop and weakness. To evaluate for peroneal nerve palsy, nerve conduction studies are performed on the peroneal nerve, including both proximal and distal stimulations (one study). Further studies may assess the tibial nerve and sural nerve to identify if multiple nerves are affected. , Following a traumatic injury, a patient has forearm weakness. To investigate potential radial nerve damage, nerve conduction studies are conducted on the radial nerve and other nerves in the arm to isolate the location and extent of the injury.
Documentation should include the reason for the study, the nerves tested, the stimulation and recording sites, the waveforms obtained, the calculated conduction velocities and latencies, comparison to normal values, a summary of clinical and electrodiagnostic findings, and the physician's interpretation and diagnosis.
