Official Description

Insertion of pacemaker pulse generator only; with existing dual leads

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 33213 involves the insertion of a permanent cardiac pacemaker pulse generator when dual leads are already in place. A cardiac pacemaker is a medical device that delivers electrical impulses to the heart, ensuring it beats at a consistent and appropriate rate, thereby maintaining a normal cardiac rhythm. This is particularly important for patients whose hearts may not function effectively on their own due to various cardiac conditions. The pacemaker system can consist of one or more leads, which are the wires that connect the pulse generator to the heart. These leads can be positioned either on the surface of the heart (epicardial) or within the heart chambers (endocardial). During the procedure, a surgical incision is typically made in the left pectoral region, where a subcutaneous pocket is created to house the pulse generator. The existing leads are then connected to the new pulse generator, which is subsequently tested to ensure proper functionality. Once confirmed that the leads and generator are operating correctly, the pulse generator is securely placed into the pocket, sutured to the underlying tissue, and the incision site is closed. This procedure is specifically coded as 33213 when it is performed with existing dual leads, distinguishing it from other codes that may apply to different configurations of pacemaker systems or lead placements.

1. Indications

The insertion of a pacemaker pulse generator using CPT® Code 33213 is indicated for patients who require the support of a cardiac pacemaker due to various heart rhythm disorders. The specific indications for this procedure include:

  • Bradycardia: A condition characterized by an abnormally slow heart rate, which may lead to insufficient blood flow to the body.
  • Heart Block: A condition where the electrical signals in the heart are delayed or blocked, preventing the heart from beating effectively.
  • Post-Myocardial Infarction: Patients who have experienced a heart attack may require a pacemaker to manage their heart rhythm.
  • Cardiac Syncope: Episodes of fainting or near-fainting due to inadequate heart rate response.

2. Procedure

The procedure for the insertion of a pacemaker pulse generator with existing dual leads involves several critical steps, which are detailed as follows:

  • Step 1: The patient is positioned appropriately, and the surgical site is prepared and sterilized to minimize the risk of infection.
  • Step 2: An incision is made in the skin, typically located in the left pectoral region, to access the area where the pulse generator will be placed.
  • Step 3: A subcutaneous pocket is created in the tissue beneath the skin to accommodate the pacemaker pulse generator securely.
  • Step 4: The existing dual leads are carefully connected to the new pulse generator, ensuring proper attachment for effective electrical conduction.
  • Step 5: The functionality of the leads and the pulse generator is tested to confirm that they are operating correctly and delivering the appropriate electrical impulses.
  • Step 6: Once the testing is successful, the pulse generator is placed into the subcutaneous pocket, and it is sutured to the underlying tissue to secure it in place.
  • Step 7: The incision site is then closed using sutures, and appropriate dressings are applied to protect the area during the initial healing phase.

3. Post-Procedure

After the insertion of the pacemaker pulse generator, patients are typically monitored for any immediate complications, such as infection or lead displacement. Post-procedure care includes instructions on activity restrictions, wound care, and signs of potential complications that should prompt immediate medical attention. Patients may also require follow-up appointments to assess the pacemaker's function and make any necessary adjustments. Recovery time can vary, but most patients are advised to avoid strenuous activities for a specified period to ensure proper healing and integration of the device.

KX Requirements specified in the medical policy have been met
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
