CPT® Code 33233

The procedure described by CPT® Code 33233 involves the removal of a permanent pacemaker pulse generator without the immediate intention of replacement. A permanent pacemaker is a medical device implanted in patients to help regulate heart rhythms, and the pulse generator is the component that produces electrical impulses to stimulate the heart. The removal of the pulse generator may be necessitated by various complications, including pressure necrosis, which is tissue damage due to prolonged pressure; skin pocket hematoma, which is a localized collection of blood outside of blood vessels; or infection, which can compromise the integrity of the device and surrounding tissues. During the 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 surgeon carefully disconnects the electrodes that connect the pulse generator to the heart and meticulously dissects the generator from the surrounding tissue to facilitate its removal. In cases where the generator is being taken out due to malfunction or battery depletion, a new generator may be inserted. However, if the removal is for other reasons, the surgical site may be treated by debriding the skin pocket, leaving it open to allow for drainage, or closing it to promote healing.
