Official Description

Open repair of infrarenal aortic aneurysm or dissection, plus repair of associated arterial trauma, following unsuccessful endovascular repair; tube prosthesis

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 34830 refers to the open surgical repair of an infrarenal aortic aneurysm or dissection, which is a serious condition characterized by the abnormal dilation or tearing of the aorta located just below the renal arteries. This procedure is specifically indicated when previous attempts at endovascular repair have been unsuccessful. Endovascular repair is a minimally invasive technique that may lead to complications such as endoleaks, dissection, or occlusion of major aortic branches, which can compromise blood flow to the aorta or iliac regions. The open repair involves a more invasive approach, requiring an abdominal incision to access the aorta and associated vessels. During the procedure, the surgeon will remove any thrombus and lodged pieces of the endograft, ensuring that the prosthesis is securely sutured to the healthy sections of the aorta. This comprehensive approach aims to restore normal vascular flow and address any arterial trauma that may have occurred as a result of the aneurysm or previous repair attempts.

1. Indications

The open repair of an infrarenal aortic aneurysm or dissection, as described by CPT® Code 34830, is indicated in the following situations:

  • Unsuccessful Endovascular Repair This procedure is performed when previous endovascular repair attempts have failed, leading to complications that necessitate a more invasive surgical approach.
  • Endoleaks The presence of endoleaks, which are leaks that occur between the endograft and the aortic wall, can compromise the effectiveness of the endovascular repair and require open intervention.
  • Aortic Dissection Aortic dissection, a serious condition where the layers of the aorta separate, may necessitate open repair if it cannot be adequately addressed through endovascular means.
  • Occlusion of Major Aortic Branches If there is occlusion of major aortic branches or significant compromise of blood flow to the aorta or iliac regions, open repair may be required to restore proper circulation.

2. Procedure

The procedure for open repair of an infrarenal aortic aneurysm or dissection involves several critical steps:

  • Abdominal Incision The surgeon begins by making an abdominal incision to access the aorta and the iliac/femoral vessels. This incision allows for direct visualization and manipulation of the vascular structures involved.
  • Administration of Heparin and Placement of Vascular Clamps After the incision, intravenous heparin is administered to prevent clotting during the procedure. Vascular clamps are then placed above and below the aneurysm to control blood flow and create a bloodless field for the repair.
  • Opening the Aneurysm The aneurysm is carefully opened, and any thrombus present within the aneurysm sac is removed to facilitate a clean repair. This step is crucial for ensuring that the prosthesis can be securely attached to healthy aortic tissue.
  • Removal of Endograft Pieces If any pieces of the previously placed endograft are lodged within the aorta, they are removed during this step to prevent further complications and ensure a smooth repair process.
  • Suturing the Prosthesis The tube prosthesis is then sutured to the untraumatized aorta above the aneurysm at the proximal end. This connection is vital for restoring normal blood flow through the aorta.
  • Checking Vascular Flow After suturing the proximal end, vascular flow is checked to ensure that blood is flowing correctly through the newly placed prosthesis. Additional sutures are placed as needed to secure the prosthesis firmly.
  • Repairing the Distal End The distal end of the prosthesis is then repaired in a similar fashion, either in the aorta or the iliac/femoral artery(s). Again, vascular flow is checked, and additional sutures are placed as necessary.
  • Removal of Vascular Clamps and Closure Once the repairs are complete and vascular flow is confirmed, the vascular clamps are removed. Anticoagulation is reversed, bleeding is controlled, and the surgical wound is then closed.

3. Post-Procedure

Post-procedure care following the open repair of an infrarenal aortic aneurysm or dissection includes monitoring for any signs of complications such as bleeding, infection, or graft failure. Patients may require close observation in a recovery unit, and follow-up imaging studies may be necessary to assess the integrity of the repair and ensure proper blood flow. Pain management and rehabilitation may also be part of the recovery process, depending on the individual patient's needs and the extent of the surgical intervention.

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).
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.
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).
