(Active) Effective Date: N/A Revision Date: N/A Vascular Surgery - Surgical Procedures on Arteries and Veins Surgery Feed
Endovascular repair of the visceral and infrarenal abdominal aorta using a fenestrated visceral aortic endograft and a concomitant unibody or modular infrarenal aortic endograft, including two visceral artery endoprostheses.
Modifiers may be applicable depending on the circumstances of the procedure (e.g., 51 for multiple procedures, 58 for staged procedures, 76 for repeat procedures).Consult the most up to date CPT manual.
Medical necessity is established by the presence of an aneurysm, pseudoaneurysm, dissection, penetrating ulcer, intramural hematoma, or traumatic disruption of the visceral and/or infrarenal aorta threatening organ perfusion or risking rupture.The procedure is medically necessary to prevent catastrophic events.
The physician is responsible for pre-operative planning (including imaging review and 3D modeling,minimum 90 minutes),the endovascular procedure (including access site creation, device placement, angiographic imaging), and post-operative care.
In simple words: This code covers a complex procedure to repair a weakened or damaged area in the main blood vessel in the abdomen (aorta).A special type of stent-graft (with small openings) is used, along with additional smaller stents placed in branches of the aorta to keep blood flowing correctly.
Endovascular repair of the visceral aorta and infrarenal abdominal aorta (e.g., aneurysm, pseudoaneurysm, dissection, penetrating ulcer, intramural hematoma, or traumatic disruption) with a fenestrated visceral aortic endograft and concomitant unibody or modular infrarenal aortic endograft.This includes all associated radiological supervision and interpretation, including target zone angioplasty when performed; and includes two visceral artery endoprostheses (superior mesenteric, celiac, and/or renal artery[s]).
Example 1: A 70-year-old male presents with a large abdominal aortic aneurysm involving the visceral and infrarenal aorta.A fenestrated endograft is planned and deployed with two additional visceral artery endoprostheses to preserve blood flow to the superior mesenteric and celiac arteries., A 65-year-old female with a type B aortic dissection extending into the infrarenal and visceral aorta undergoes endovascular repair with a fenestrated endograft and two additional visceral artery endoprostheses to protect the celiac and renal arteries., An 80-year-old male with a complex abdominal aortic aneurysm involving the visceral aorta with significant calcification is treated using a fenestrated endograft and two visceral artery endoprostheses.Angioplasty of the target area is also performed.
Detailed pre-operative imaging studies (CTA or MRA), operative report specifying the type of endograft used and the number and location of fenestrations and endoprostheses, post-operative angiogram showing the patency of the visceral arteries and the absence of endoleaks.
** This procedure is complex and requires a high level of technical expertise.Thorough documentation is critical for accurate coding and reimbursement. The specific types of endografts and endoprostheses utilized should be clearly documented.
