Aortoiliac Aneurysm Repair
A patient underwent an open aortoiliac aneurysm repair. During the procedure, the aortoiliac bifurcation was dissected free down to the iliac bifurcation points. Both common iliacs were noted to be densely calcified with a palpable stent in the right common iliac and an aneurysm in the left common iliac. At the left iliac bifurcation, the external and internal iliac arteries were separately dissected free. The infrarenal abdominal aorta was dissected free, skeletonized and circumscribed. The aneurysm was opened. A Dacron bifurcation graft was sewn end-to-end to the infrarenal abdominal aorta. Next, the left common iliac bifurcation was endarterectomized to enable suture to this bifurcation. The right limb of the Dacron graft was tunneled anatomically beneath both ureters, down to the right groin and sewn end-to-side to an arteriotomy in the common femoral artery. Flow was restored to the internal iliac on the left and the profunda femoris on the right. What are the appropriate ICD-10-PCS codes for the aortoiliac aneurysm repair? In this case, would replacement or bypass be assigned as the root operation or a combination of these root operations? ...

Article Overview
This article reviews an open vascular surgery case involving repair of an aortoiliac aneurysm with graft placement and reconstruction of associated arterial segments. It is intended for coders, CDI specialists, and vascular surgery documentation reviewers who need to understand how the operative approach, anatomic sites, and repair components affect ICD-10-PCS code selection. The discussion focuses on procedure interpretation and the coding framework for complex aortoiliac repair.
Why This Topic Matters
Accurate reporting of complex open vascular repairs depends on recognizing the anatomy addressed, the type of reconstruction performed, and how multiple operative components are reflected in ICD-10-PCS.
