Official Description

Removal of permanent pacemaker pulse generator with replacement of pacemaker pulse generator; single lead system

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A permanent pacemaker pulse generator is a medical device that helps regulate the heartbeat in patients with certain heart conditions. The procedure described by CPT® Code 33227 involves the removal of an existing permanent pacemaker pulse generator, which may be necessary due to issues such as malfunction or the depletion of the generator's battery. 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 healthcare provider disconnects the electrodes from the old generator, carefully dissects it from the surrounding tissue, and removes it from the body. Following the removal, a new pulse generator is inserted, which is connected to the existing lead(s) to ensure continuity of cardiac pacing. The functionality of the new device is tested to confirm that it is operating correctly before it is secured in place and the incision is closed. This procedure is specifically for a single lead system, and alternative codes are available for dual and multiple lead systems, ensuring accurate coding and billing for the specific type of pacemaker replacement performed.

1. Indications

The procedure described by CPT® Code 33227 is indicated for patients who require the replacement of a permanent pacemaker pulse generator due to specific conditions or symptoms. These may include:

  • Malfunction of the Existing Generator The current pulse generator may not be functioning properly, leading to inadequate pacing of the heart.
  • Battery Depletion The battery of the existing pulse generator is nearing the end of its life, necessitating replacement to maintain effective cardiac function.

2. Procedure

The procedure for the removal and replacement of a permanent pacemaker pulse generator involves several critical steps, which are detailed as follows:

  • Step 1: Incision and Access A surgical incision is made in the skin over the site of the existing pulse generator. This incision allows the healthcare provider to access the skin pocket where the generator is located.
  • Step 2: Opening the Skin Pocket The skin pocket is carefully opened to expose the pulse generator. This step is crucial for ensuring that the device can be safely removed without damaging surrounding tissues.
  • Step 3: Disconnecting Electrodes The electrodes connected to the existing pulse generator are disconnected. This step is necessary to separate the old generator from the leads that will be used with the new device.
  • Step 4: Removal of the Old Generator The pulse generator is dissected free from the surrounding tissue and removed from the body. Care is taken to minimize trauma to the surrounding area during this process.
  • Step 5: Insertion of the New Generator A new pulse generator is then attached to the existing lead(s). This connection is vital for ensuring that the new device can effectively pace the heart.
  • Step 6: Testing the New Generator Once the new pulse generator is in place, it is tested to confirm that both the leads and the generator are functioning as intended. This testing is essential to ensure proper cardiac pacing.
  • Step 7: Securing the New Generator After successful testing, the new pulse generator is placed into the pocket created earlier. It is then sutured to the underlying tissue to secure it in place.
  • Step 8: Closing the Pocket Finally, the skin pocket is closed, completing the procedure. Proper closure is important for minimizing the risk of infection and promoting healing.

3. Post-Procedure

Post-procedure care following the replacement of a permanent pacemaker pulse generator includes monitoring the patient for any immediate complications, such as infection or bleeding at the incision site. Patients may be advised to limit physical activity for a specified period to allow for proper healing. Follow-up appointments are typically scheduled to assess the function of the new pulse generator and to ensure that the leads remain properly positioned. Patients should also be educated on signs of potential complications, such as unusual swelling, redness, or pain at the site of the incision, and instructed to seek medical attention if these occur.

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).
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.)
