Official Description

Relocation of skin pocket for implantable defibrillator

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 33223 involves the relocation of the skin pocket for an implantable defibrillator. This surgical intervention is necessary when the existing skin pocket, which houses the generator of the cardiac device, becomes problematic. Common reasons for this relocation include pain or discomfort at the current site, which may arise from various factors such as pressure on the surrounding tissue, necrosis (tissue death), or erosion of the skin. Additionally, complications like a hematoma, which is a localized collection of blood outside of blood vessels, or an infection can necessitate the relocation of the skin pocket. During the procedure, a surgical incision is made over the generator, allowing access to the skin pocket. The generator is then carefully removed for inspection, and any issues such as hematomas or infections are addressed before creating a new skin pocket at a different site. This ensures that the implantable defibrillator can be securely placed in a location that minimizes discomfort and reduces the risk of further complications.

1. Indications

The relocation of the skin pocket for an implantable defibrillator is indicated in the following situations:

  • Pain or Discomfort - Patients may experience pain or discomfort at the existing skin pocket site, which can be due to various underlying issues.
  • Pressure - Excessive pressure on the surrounding tissue can lead to complications that necessitate the relocation of the skin pocket.
  • Necrosis - The presence of necrotic tissue, or tissue death, at the current site can compromise the integrity of the skin pocket, requiring surgical intervention.
  • Erosion - Erosion of the skin surrounding the pocket can occur, leading to the need for a new site to ensure proper placement of the device.
  • Skin Pocket Hematoma - A hematoma may form in the skin pocket, necessitating evacuation and relocation to prevent further complications.
  • Infection - If an infection is present, it may require flushing and treatment, along with the relocation of the skin pocket to a healthier site.

2. Procedure

The procedure for relocating the skin pocket for an implantable defibrillator involves several critical steps:

  • Step 1: Incision - A surgical incision is made over the existing pacemaker or implantable defibrillator generator to access the skin pocket.
  • Step 2: Opening the Skin Pocket - The skin pocket is carefully opened to allow for the removal of the generator and inspection of the surrounding tissue.
  • Step 3: Inspection and Treatment - The generator is removed, and the skin pocket is inspected for any complications. If a hematoma is present, it is evacuated to prevent further issues. In cases of infection, the pocket may be flushed with an antibiotic solution to address the infection.
  • Step 4: Debridement - The skin and subcutaneous tissue may be debrided to remove any necrotic or infected tissue, ensuring a clean site for the new pocket.
  • Step 5: Closing the Old Pocket - After addressing any complications, the old skin pocket is closed to promote healing.
  • Step 6: Creating a New Skin Pocket - A new site is selected, and a new skin pocket is fashioned to accommodate the generator securely.
  • Step 7: Connecting Leads - The leads are then connected to the pulse generator, and the system is tested to ensure proper functionality.
  • Step 8: Inserting the Generator - Once confirmed that the leads and generator are functioning correctly, the generator is inserted into the newly fashioned pocket.
  • Step 9: Suturing - The generator is sutured to the underlying tissue to secure it in place, and the new skin pocket is closed over the generator.

3. Post-Procedure

Post-procedure care for the relocation of the skin pocket for an implantable defibrillator includes monitoring the surgical site for signs of infection, ensuring proper healing, and managing any discomfort the patient may experience. Patients may be advised on activity restrictions to promote healing and prevent complications. Follow-up appointments are essential to assess the integrity of the new skin pocket and the functionality of the implantable defibrillator. Any concerns regarding the surgical site or device performance should be promptly addressed by healthcare professionals.

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.
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).
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.
24 Unrelated evaluation and management service by the same physician or other qualified health care professional during a postoperative period: the physician or other qualified health care professional may need to indicate that an evaluation and management service was performed during a postoperative period for a reason(s) unrelated to the original procedure. this circumstance may be reported by adding modifier 24 to the appropriate level of e/m service.
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient 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).
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.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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.)
