Removal of permanent pacemaker pulse generator only

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

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.

1. Indications

The removal of a permanent pacemaker pulse generator, as indicated by CPT® Code 33233, is performed under specific circumstances that necessitate intervention. These indications include:

  • Pressure Necrosis - This condition arises when there is prolonged pressure on the skin over the pacemaker pocket, leading to tissue damage that may require the generator's removal.
  • Skin Pocket Hematoma - A hematoma can form in the area where the pacemaker is implanted, causing swelling and discomfort, which may necessitate the removal of the pulse generator.
  • Infection - Infections at the site of the pacemaker can pose serious health risks, making it essential to remove the generator to prevent further complications.

2. Procedure

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

  • Step 1: Incision - The surgeon begins by making an incision in the skin directly over the existing pulse generator. This incision allows access to the skin pocket where the generator is located.
  • Step 2: Opening the Skin Pocket - Once the incision is made, the skin pocket is carefully opened to expose the pulse generator. This step is crucial for accessing the device and the surrounding tissues.
  • Step 3: Disconnecting Electrodes - The next step involves disconnecting the electrodes that link the pulse generator to the heart. This disconnection is necessary to safely remove the generator without causing damage to the heart or surrounding structures.
  • Step 4: Dissecting the Generator - The surgeon then meticulously dissects the pulse generator free from the surrounding tissue. This step requires careful handling to avoid injury to nearby structures and to ensure a clean removal.
  • Step 5: Removal of the Generator - After the generator is fully dissected, it is removed from the skin pocket. If the removal is due to malfunction or battery replacement, a new pulse generator may be inserted at this time.
  • Step 6: Post-Removal Care - If the generator is removed for reasons other than malfunction, the surgeon may choose to debride the skin pocket, leave it open for drainage, or close it to promote healing, depending on the specific circumstances of the case.

3. Post-Procedure

After the removal of the permanent pacemaker pulse generator, post-procedure care is essential to ensure proper healing and to monitor for any complications. The surgical site may require regular dressing changes, and the patient should be observed for signs of infection, such as increased redness, swelling, or discharge. If the skin pocket was left open, it is important to manage drainage effectively to prevent complications. Follow-up appointments may be necessary to assess the healing process and to determine if further interventions, such as the insertion of a new pulse generator, are required. Patients should also be advised on activity restrictions and signs to watch for that may indicate complications.

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).
GC This service has been performed in part by a resident under the direction of a teaching physician
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.)
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.
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.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
74 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
