2025 CPT code 34710
(Active) Effective Date: N/A Revision Date: N/A Vascular Surgery - Endovascular Procedures Surgery Feed
Delayed placement of an extension prosthesis (tube graft) for endovascular repair of an infrarenal abdominal aortic or iliac aneurysm, false aneurysm, dissection, endoleak, or endograft migration.
Modifiers may be applicable depending on the circumstances of the procedure (e.g., 50 for bilateral procedures, 59 for distinct procedural services, etc.).
Medical necessity for code 34710 is established by the presence of an infrarenal abdominal aortic or iliac aneurysm, false aneurysm, dissection, endoleak, or endograft migration identified on imaging studies. The procedure is necessary to prevent complications such as rupture, further dissection, or organ damage.
The vascular surgeon is responsible for planning, performing, and interpreting the results of the procedure. This includes pre-procedural planning, device selection, catheterization, deployment of the extension prosthesis, angioplasty or stenting (if needed), and post-procedural assessment.
In simple words: This code covers a procedure where a doctor places a small tube-like device into a weakened area of a large artery in the belly (aorta or iliac artery) to repair a problem such as an aneurysm (bulge), or a leak from a previously placed device. This is a follow-up procedure, done later. The procedure uses imaging to guide the placement.
This CPT code, 34710, represents the delayed placement of a distal or proximal extension prosthesis for the endovascular repair of an infrarenal abdominal aortic or iliac aneurysm, false aneurysm, dissection, endoleak, or endograft migration.The procedure encompasses pre-procedure sizing and device selection, all nonselective catheterizations, associated radiological supervision and interpretation, and treatment zone angioplasty/stenting (if performed). It applies to the initial vessel treated.Nonselective introduction of guidewires and catheters into the treatment zone from peripheral artery access is included. Balloon angioplasty and/or stenting within the treatment zone, before or after endograft deployment, along with fluoroscopic guidance and radiological supervision, are also inherent to the code.Selective catheterization of arteries outside the treatment zone may be separately reported.
Example 1: A 70-year-old male patient with a previously placed abdominal aortic aneurysm endograft presents with an endoleak identified on surveillance imaging.An extension graft is placed to seal the leak. Code 34710 would be used., A 65-year-old female patient underwent an endovascular abdominal aortic aneurysm repair 6 months prior.Follow-up imaging reveals migration of the endograft.A delayed extension graft is placed to stabilize the device. Code 34710 is appropriate., A 55-year-old male patient with a history of infrarenal aortic dissection experienced an extension of the dissection.A delayed extension prosthesis is inserted to treat the condition.34710 would be applied.
Pre-operative imaging demonstrating the need for the extension graft (e.g., CT angiogram, MRI).Operative report detailing the procedure, including catheterization techniques, device selection, and placement of the extension.Post-operative imaging confirming successful placement and exclusion of the aneurysm or other pathology.
** The selection of code 34710 versus other similar codes (34709, 34711) depends heavily on the timing of the procedure. 34710 is specifically for delayed placement.
