Official Description

Direct repair of aneurysm, pseudoaneurysm, or excision (partial or total) and graft insertion, with or without patch graft; for ruptured aneurysm, abdominal aorta involving iliac vessels (common, hypogastric, external)

Common Language Description

The CPT® Code 35103 refers to the surgical procedure for the direct repair of a ruptured abdominal aortic aneurysm or pseudoaneurysm, particularly when there is involvement of the iliac vessels, which include the common, hypogastric, and external iliac arteries. An abdominal aortic aneurysm is characterized by an abnormal enlargement or dilation of the abdominal aorta, which can lead to serious complications if not addressed promptly. The condition may arise from various factors, including arteriosclerosis, mechanical obstructions, or less common causes such as infections or vessel wall abnormalities. A pseudoaneurysm, in contrast, is a hematoma that forms outside the arterial wall and is typically the result of trauma or procedural complications, distinguishing it from a true aneurysm that involves all three layers of the artery wall. During the procedure, a surgical incision is made to access the abdominal aorta, allowing the surgeon to directly repair or excise the aneurysm and insert a graft, which may or may not include a patch graft. This intervention is critical in emergency situations where a ruptured aneurysm poses an immediate risk of significant blood loss. The surgical approach involves careful dissection and clamping of the aorta and iliac arteries to control bleeding, followed by the removal of any thrombus within the aneurysm sac and the placement of a synthetic graft to restore normal blood flow. The procedure is complex and requires meticulous attention to detail to ensure successful outcomes and minimize complications.

1. Indications

The procedure described by CPT® Code 35103 is indicated for the following conditions:

  • Ruptured Abdominal Aortic Aneurysm - This condition involves a tear in the wall of the aneurysm, leading to internal bleeding and requiring immediate surgical intervention.
  • Pseudoaneurysm - This is indicated when there is a hematoma that communicates with the arterial lumen, often resulting from trauma or procedural complications.
  • Iliac Vessel Involvement - The procedure is specifically indicated when the aneurysm or pseudoaneurysm affects the iliac vessels, which are critical for blood supply to the pelvis and lower extremities.

2. Procedure

The surgical procedure for CPT® Code 35103 involves several critical steps to ensure effective repair of the ruptured aneurysm:

  • Step 1: Incision and Access - A midline abdominal, transverse, or retroperitoneal flank incision is made to gain access to the abdominal aorta. The overlying soft tissues are carefully divided to expose the aorta.
  • Step 2: Dissection and Exposure - The duodenum is dissected away from the aorta to fully expose the vessel. This step is crucial for visualizing the aneurysm and surrounding structures.
  • Step 3: Establishing Control - Proximal control is established below the renal arteries, and distal control is secured beyond the iliac artery aneurysm to manage blood flow during the repair.
  • Step 4: Clamping - The iliac arteries are clamped below the level of the aneurysm, and the proximal aorta is also clamped to prevent further bleeding during the procedure.
  • Step 5: Aneurysm Sac Management - The aneurysm sac is opened longitudinally, and any aortic thrombus is removed to prepare for graft insertion. The lumbar arteries and inferior mesenteric artery are oversewn to minimize blood loss.
  • Step 6: Graft Insertion - A synthetic iliac bifurcation graft is sutured to the healthy aorta proximal to the aneurysm and to the healthy iliac artery distal to the aneurysm, effectively bypassing the damaged area.
  • Step 7: Closure - After the graft is securely placed, the aneurysm sac is closed over the graft. The clamps are then released to restore blood flow, and the retroperitoneum is repaired before closing the abdomen.

3. Post-Procedure

Post-procedure care following the surgical repair of a ruptured abdominal aortic aneurysm involves monitoring for complications such as bleeding, infection, or graft failure. Patients are typically observed in a critical care setting initially due to the nature of the emergency procedure. Recovery may include pain management, fluid resuscitation, and monitoring vital signs closely. Follow-up imaging may be required to assess the integrity of the graft and ensure proper healing. Patients are also advised on lifestyle modifications and may require rehabilitation to regain strength and mobility following the surgery.

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.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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).
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.
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.)
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).
