Official Description

Direct repair of aneurysm, pseudoaneurysm, or excision (partial or total) and graft insertion, with or without patch graft; for ruptured aneurysm, carotid, subclavian artery, by neck incision

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 35002 refers to the surgical procedure involving the direct repair of a ruptured aneurysm or pseudoaneurysm of the carotid or subclavian artery. This procedure may also include the excision of the aneurysm, either partially or totally, along with the insertion of a graft, which may or may not involve a patch graft. Aneurysms are characterized by an abnormal enlargement or dilation of an artery, which can arise from various causes, including arteriosclerosis, mechanical obstructions, or abnormalities in the vessel wall. Pseudoaneurysms, on the other hand, are not true aneurysms as they do not involve all three layers of the arterial wall and are often the result of trauma or procedural complications. The surgical approach typically involves a neck incision to access the affected artery, allowing for the necessary repairs or grafting to restore normal blood flow. This procedure is classified as an emergency intervention due to the nature of a ruptured aneurysm, which requires immediate attention to control bleeding and prevent further complications.

1. Indications

The procedure described by CPT® Code 35002 is indicated for the following conditions:

  • Ruptured Aneurysm - A life-threatening condition where the aneurysm has burst, leading to internal bleeding that requires immediate surgical intervention.
  • Pseudoaneurysm - A condition where a hematoma forms in communication with the artery wall, often resulting from trauma or complications from medical procedures.
  • Carotid Artery Aneurysm - An abnormal dilation of the carotid artery that may lead to serious complications if not addressed promptly.
  • Subclavian Artery Aneurysm - Similar to carotid artery aneurysms, these can pose significant risks and require surgical repair to prevent rupture or other complications.

2. Procedure

The procedure for CPT® Code 35002 involves several critical steps to ensure effective repair of the aneurysm or pseudoaneurysm:

  • Step 1: Preparation and Anesthesia - The patient is positioned appropriately, and the surgical site is prepped and draped. General anesthesia is typically administered to ensure the patient is comfortable and pain-free during the procedure.
  • Step 2: Incision - A neck incision is made to access the carotid or subclavian artery. In cases where the subclavian artery is involved, a portion of the clavicle may be excised to facilitate better access.
  • Step 3: Exposure of the Artery - The overlying soft tissues, including the platysma and/or scalene muscles, are carefully divided while protecting the phrenic nerve. This step allows for the exposure of the underlying artery, which may include the common carotid, internal carotid, external carotid, or subclavian artery.
  • Step 4: Clamping the Arteries - The subclavian, common carotid, and innominate arteries are clamped as necessary to control blood flow and minimize bleeding during the repair process.
  • Step 5: Aneurysm Sac Management - The aneurysm sac is opened, and any thrombus or plaque is removed to prepare the artery for repair. The walls of the artery are then sutured to restore integrity.
  • Step 6: Graft Insertion - Depending on the specific case, an autogenous (saphenous vein) or synthetic patch graft may be applied. Alternatively, the aneurysm may be excised, and an end-to-end anastomosis of the distal and proximal vessel ends may be performed, with or without a patch graft.
  • Step 7: Tube Graft Placement - In some cases, a tube graft is inserted through a longitudinal incision in the artery and sutured to healthy artery tissue both distal and proximal to the aneurysm. The aneurysm sac is then closed over the graft.
  • Step 8: Completion of Repair - Once the repair is completed, the clamps are released, and blood flow is re-established through the artery.

3. Post-Procedure

After the procedure, the patient is monitored closely for any signs of complications, such as bleeding or infection. Recovery may involve a stay in the hospital for observation, and the patient may require follow-up imaging studies to ensure the success of the repair. Pain management and rehabilitation may also be part of the post-procedure care plan, depending on the individual patient's needs and the extent of the surgery performed.

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.
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.
