Official Description

Direct repair of aneurysm, pseudoaneurysm, or excision (partial or total) and graft insertion, with or without patch graft; for ruptured aneurysm, axillary-brachial artery, by arm incision

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 35013 refers to the surgical procedure for the direct repair of an aneurysm or pseudoaneurysm, specifically targeting the axillary-brachial artery through an incision in the arm. An aneurysm is characterized by an abnormal enlargement or dilation of an artery, which can arise from various causes, including arteriosclerosis, mechanical obstructions like thoracic outlet syndrome, or abnormalities in the vessel wall such as fibromuscular dysplasia. Pseudoaneurysms, on the other hand, differ from true aneurysms as they do not involve all three layers of the arterial wall and are often the result of trauma or complications from medical procedures, leading to a pulsating hematoma that communicates with the artery wall. The procedure involves either direct repair or excision of the aneurysm, with the potential insertion of a graft, which may be autogenous (using the patient's own saphenous vein) or synthetic. The surgical approach requires careful exposure of the axillary-brachial artery, clamping to control blood flow, and meticulous repair of the artery walls, ensuring that any thrombus or plaque is removed. The procedure is performed in an emergency setting, particularly for ruptured aneurysms, necessitating immediate isolation and control of bleeding before the repair can be completed.

1. Indications

The procedure described by CPT® Code 35013 is indicated for the surgical repair of a ruptured aneurysm or pseudoaneurysm of the axillary-brachial artery. The following conditions may warrant this intervention:

  • Ruptured Aneurysm - A life-threatening condition where the aneurysm has burst, leading to significant internal bleeding that requires immediate surgical intervention.
  • Pseudoaneurysm - A condition resulting from trauma or complications from medical procedures, where a hematoma forms in communication with the artery, necessitating repair to prevent further complications.
  • Associated Occlusive Disease - Conditions that may accompany the aneurysm, affecting blood flow and requiring surgical correction to restore normal function.

2. Procedure

The surgical procedure for CPT® Code 35013 involves several critical steps to ensure effective repair of the aneurysm or pseudoaneurysm:

  • Preparation and Anesthesia - The patient is positioned appropriately, and the surgical site is prepared. Anesthesia is administered to ensure the patient is comfortable and pain-free during the procedure.
  • Incision - A longitudinal incision is made in the arm over the section of the axillary-brachial artery that is affected by the aneurysm. This incision allows access to the artery for repair.
  • Exposure of the Artery - The overlying soft tissues are carefully divided to expose the axillary-brachial artery. This step is crucial for visualizing the aneurysm and surrounding structures.
  • Clamping the Artery - The artery is clamped as necessary to control blood flow during the repair process, minimizing blood loss and allowing for a clearer surgical field.
  • Opening the Aneurysm Sac - The aneurysm sac is opened, and any thrombus or plaque present within the sac is meticulously removed to facilitate proper repair of the artery walls.
  • Repair Techniques - The surgeon may employ one of several techniques for repair:
    • Direct Repair - The walls of the artery are sutured together after the aneurysm sac is opened.
    • Patch Grafting - An autogenous (saphenous vein) or synthetic patch graft may be applied to reinforce the artery walls as needed.
    • End-to-End Anastomosis - The aneurysm may be excised, and the ends of the artery are directly connected, with or without a patch graft.
    • Tube Grafting - A longitudinal incision is made in the artery, and a tube graft is inserted and sutured to healthy artery segments distal and proximal to the aneurysm.
  • Closure of the Aneurysm Sac - After the graft or repair is completed, the aneurysm sac is closed over the graft to restore the integrity of the artery.
  • Re-establishing Blood Flow - Once the repair is finalized, the clamps are released, and blood flow is re-established through the artery.

3. Post-Procedure

Post-procedure care following the repair of a ruptured aneurysm involves monitoring the patient for any signs of complications, such as bleeding or infection. The surgical site will be assessed for proper healing, and the patient may require pain management and supportive care during recovery. Follow-up imaging may be necessary to ensure the success of the repair and to monitor for any potential recurrence of the aneurysm. The patient will also be advised on activity restrictions and signs to watch for that may indicate complications.

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).
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.)
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.)
