CPT® Code 33273

The procedure described by CPT® Code 33273 involves the repositioning of a previously implanted subcutaneous implantable defibrillator electrode. This procedure may be necessary when there is movement of the electrode, which can affect the device's functionality and the patient's safety. The process is performed under general anesthesia or monitored anesthesia care (MAC), along with local anesthesia to ensure patient comfort. The surgical area, specifically the anterior and left lateral chest, is meticulously prepped and draped to maintain a sterile environment. The procedure requires careful dissection to access the pulse generator pocket, where the electrode is located. The electrode is then disconnected from the pulse generator, allowing for repositioning. This involves the use of a sheath and possibly a tunneling tool to navigate the electrode through the subcutaneous tissue, ensuring it is placed back into an optimal position. After repositioning, the electrode is reconnected to the pulse generator, and the device is tested to confirm its proper functioning before the incisions are closed. This detailed approach ensures that the electrode is accurately placed, which is critical for the effective operation of the implantable defibrillator.
