Transcutaneous magnetic stimulation by focused low-frequency electromagnetic pulse, peripheral nerve, with identification and mapping of the treatment location, including noninvasive electroneurographic localization (nerve conduction localization), when performed; first nerve

Transcutaneous magnetic stimulation (TMS) is a non-invasive therapeutic technique that utilizes focused low-frequency electromagnetic pulses to stimulate peripheral nerves. This procedure is particularly aimed at managing chronic pain, especially following traumatic injuries. The process begins with the identification of the specific nerve location associated with pain, which may be at the trauma site or adjacent to a palpable neuroma. The clinician employs a specialized device that emits electromagnetic impulses, moving the coil head along the targeted area to accurately locate the nerve causing discomfort. As the patient indicates the precise point of pain, the amplitude of the electromagnetic impulse is gradually increased to optimize stimulation until the patient reports achieving a threshold of pain relief. To ensure accurate future treatments, the identified location is marked on the skin with permanent ink, and a photograph is taken to document the position of the coil head during stimulation. The actual treatment involves delivering electromagnetic pulses to the painful nerve for a duration of approximately 15 to 20 minutes. For billing purposes, CPT® Code 0766T is reported for the first nerve treated, which includes the identification and marking process, while CPT® Code 0767T is used for each additional nerve treated and marked.
