Feb 2016 CPT Assistant Q&A:
Question: Is it appropriate to report CPT code 95937, Neuromuscular junction testing (repetitive stimulation, paired stimuli), each nerve, any 1 method, for train of four testing during intraoperative neural monitoring?
Answer:A peripheral nerve stimulator, also known as a train‐of‐four monitor, is used to assess neuromuscular transmission when neuromuscular blocking agents are given to block musculoskeletal activity. By assessing the
depth of neuromuscular blockade, peripheral nerve stimulation can ensure proper medication dosing and, thus, decrease the incidence of side effects. Train‐of‐four monitoring is bundled with the intraoperative neuromonitoring of electromyography (EMG) or motor evoked potentials (MEP) and, therefore, is not separately reportable.
