34201

Femoropopliteal or Aortoiliac Embolectomy/Thrombectomy via Leg Incision

CPT code 34201 describes a surgical procedure focused on the removal of an embolus (a traveling clot) or a thrombus (a stationary clot) from the femoropopliteal or aortoiliac arterial segments. This procedure is performed through an open incision in the leg, most commonly a longitudinal or transverse incision in the groin area to access the common femoral artery. This is an urgent or emergent surgical intervention typically necessitated by Acute Limb Ischemia (ALI), a condition where blood flow to the extremity is suddenly blocked, risking tissue necrosis and limb loss. During the procedure, the surgeon identifies the affected artery, performs an arteriotomy (a surgical opening into the artery), and uses a specialized embolectomy catheter, often referred to as a Fogarty catheter. The catheter is inserted past the site of the blockage; the balloon at the tip is then inflated and carefully retracted, dragging the obstructive material out through the arteriotomy. This process may be repeated multiple times in both proximal (towards the aorta) and distal (towards the foot) directions to ensure the entire arterial tree is cleared of debris. The surgeon evaluates for 'in-flow' from the iliac system and 'back-bleeding' from the distal vessels to confirm successful revascularization. Once the blockage is cleared, the artery is repaired, sometimes using a patch angioplasty to prevent narrowing, and the surgical site is closed in layers. This code specifically applies when the access point is the leg, even if the catheter is advanced proximally into the aortoiliac system.

Clinical Indications

  • Acute limb ischemia (ALI) of the lower extremity
  • Arterial embolism originating from the heart or proximal aneurysms
  • Acute-on-chronic arterial thrombosis
  • Failure or thrombosis of a previous femoropopliteal bypass graft
  • Thrombotic occlusion of the common femoral, superficial femoral, or popliteal arteries
  • Aortoiliac occlusive disease presenting with acute distal embolization (Blue Toe Syndrome)
  • Traumatic arterial thrombosis

Procedure Steps

  1. The patient is placed in a supine position and general or regional anesthesia is administered.
  2. A vertical or transverse incision is made in the groin to expose the common femoral, superficial femoral, and profunda femoris arteries.
  3. The vessels are mobilized and controlled using vascular loops or clamps.
  4. Systemic heparin is typically administered to prevent further clot formation.
  5. A longitudinal or transverse arteriotomy is performed on the common femoral artery.
  6. A Fogarty embolectomy catheter is inserted proximally into the aortoiliac segment to remove proximal thrombus (in-flow).
  7. The catheter is then inserted distally into the superficial femoral and popliteal arteries to remove distal thrombus (out-flow).
  8. The balloon is inflated and withdrawn repeatedly until no more thrombotic material is retrieved and vigorous blood flow is restored.
  9. Intraoperative fluoroscopy or arteriography may be performed to ensure the distal arterial tree is patent.
  10. The arteriotomy is closed using fine non-absorbable sutures, potentially with a synthetic or vein patch to maintain vessel caliber.
  11. Hemostasis is achieved, and the incision is closed in anatomical layers.

Coding Guidelines

  • Use code 34201 for embolectomy/thrombectomy of the femoropopliteal or aortoiliac systems through a leg incision.
  • Do not report 34201 in conjunction with 34203 (popliteal/tibial) unless a separate incision is used for the distal procedure.
  • If the procedure is performed bilaterally, append modifier -50.
  • For intraoperative radiologic supervision and interpretation, refer to 75710 or 75716, though many payers bundle basic angiography into the global surgical package for 34201.
  • If a patch angioplasty is performed to close the arteriotomy, it is typically considered bundled into the primary procedure code and not billed separately.
  • For endovascular catheter-based extraction (mechanical thrombectomy), see codes 37184-37186 instead of 34201.
  • Vascular complications of the procedure, such as a necessary bypass or repair of a ruptured vessel, may be billed separately depending on the complexity and documentation.
