Official Description

Insertion of new or replacement of permanent pacemaker with transvenous electrode(s); atrial

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 33206 involves the insertion or replacement of a permanent cardiac pacemaker system, which is a medical device designed to regulate the heart's rhythm. A permanent pacemaker consists of a pulse generator and one or more leads (electrodes) that deliver electrical impulses to the heart. These impulses help maintain a normal heart rhythm, particularly in patients with arrhythmias or other cardiac conditions that affect the heart's ability to beat effectively. The pacemaker can be configured as a single chamber, which may target either the atrium or ventricle, or as a dual chamber, which stimulates both the atrium and ventricle. During the procedure, a surgical incision is made in the upper chest to access the cephalic, subclavian, or jugular vein. A sheath is then inserted into the chosen vessel, allowing for the transvenous placement of the pacemaker leads into the heart. The leads are positioned against the heart wall to ensure effective stimulation. If a dual chamber pacemaker is required, a second lead is placed in the appropriate heart chamber. After confirming the proper function of the leads, a subcutaneous pocket is created in the left pectoral region to house the pulse generator. The leads are connected to the generator, which is then tested to ensure it operates correctly before being secured in the pocket and the incision is closed. This procedure is critical for patients who require long-term cardiac pacing to manage their heart rhythm effectively.

1. Indications

The insertion or replacement of a permanent pacemaker, as described by CPT® Code 33206, is indicated for patients experiencing specific cardiac conditions that necessitate the regulation of heart rhythm. These indications may include:

  • Bradycardia: A condition characterized by an abnormally slow heart rate, which can 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.
  • Symptomatic Atrial Fibrillation: A type of arrhythmia that may require pacing to maintain an adequate heart rate.
  • Post-Myocardial Infarction: Patients who have experienced a heart attack may require a pacemaker to support heart function.

2. Procedure

The procedure for the insertion or replacement of a permanent pacemaker involves several critical steps, which are outlined as follows:

  • Step 1: The procedure begins with the patient being positioned appropriately, and local anesthesia is administered to minimize discomfort. A surgical incision is made in the upper chest to access the cephalic, subclavian, or jugular vein.
  • Step 2: Once the vein is exposed, a sheath is inserted into the selected vessel. This sheath serves as a conduit for the pacemaker lead(s) to be advanced into the heart.
  • Step 3: Under radiological guidance, the pacemaker wire is carefully advanced through the sheath into the designated heart chamber. The lead is positioned against the wall of the heart chamber to ensure effective electrical stimulation.
  • Step 4: If a dual chamber pacemaker is indicated, a second lead is threaded into the appropriate heart chamber and positioned similarly against the heart wall.
  • Step 5: The leads are then tested to verify their proper functioning, ensuring that they can effectively deliver electrical impulses to the heart.
  • Step 6: Following successful lead testing, a second incision is made in the skin, typically in the left pectoral region, to create a subcutaneous pocket for the pulse generator.
  • Step 7: The lead(s) are connected to the pulse generator, which is then tested to confirm that it is functioning correctly.
  • Step 8: Once the leads and generator are confirmed to be operational, the pulse generator is placed into the pocket, sutured to the underlying tissue, and the incision is closed.

3. Post-Procedure

After the insertion or replacement of the permanent pacemaker, patients are typically monitored for any immediate complications. Post-procedure care may include instructions on activity restrictions, wound care, and follow-up appointments to assess the pacemaker's function. Patients may also be advised to avoid certain activities that could strain the incision site or dislodge the leads. Regular follow-up is essential to ensure the pacemaker is functioning correctly and to make any necessary adjustments to the pacing settings.

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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
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.
