CPT® Code 33229

The procedure described by CPT® Code 33229 involves the removal of a permanent pacemaker pulse generator and the subsequent replacement with a new pulse generator specifically designed for a multiple lead system. A permanent pacemaker is a medical device implanted in patients to help regulate heart rhythms, particularly in cases of arrhythmias or other cardiac conditions. The removal of the pulse generator is typically necessitated by issues such as device malfunction or when the battery life of the existing generator is nearing its end. During this procedure, a surgical incision is made over the site of the existing pulse generator, allowing access to the skin pocket where the device is housed. The electrodes connected to the pacemaker are carefully disconnected, and the generator is meticulously dissected from the surrounding tissue to ensure minimal trauma. Following the removal, a new pulse generator is attached to the existing leads, which are tested to confirm proper functionality. Once verified, the new generator is placed back into the pocket, secured to the underlying tissue, and the incision is closed. This procedure is critical for maintaining the effective functioning of the pacemaker system, particularly in patients who rely on multiple leads for optimal cardiac pacing.
