Summary & Overview
CPT 34717: Branched Iliac Endograft Placement, Adjunct to Aortoiliac Endograft
CPT code 34717 represents placement of a branched endograft in the main iliac artery and its major branches on one side of the body performed in conjunction with an aortoiliac endograft procedure to repair a rupture or other defect. This endovascular adjunct includes device sizing and selection, selective same-side catheterization, all necessary endograft extensions, angioplasty or stenting, and related radiologic supervision and interpretation when performed. Nationally, procedures involving complex iliac branch devices are clinically significant due to their role in preserving pelvic perfusion and managing life- or limb-threatening vascular injuries.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and coding parameters, payer coverage considerations, and typical sites of service. The publication provides benchmarks and policy-relevant details for billing and claims professionals, including appropriate reporting in conjunction with the primary aortoiliac endograft code, common modifiers, and expected care settings.
This summary equips clinicians, practice managers, and coding staff with the high-level information needed to recognize when CPT code 34717 applies, how it interfaces with primary endograft procedures, and where to look for payer-specific coverage and reimbursement details. Data not available in the input is noted where applicable in detailed sections.
Billing Code Overview
CPT code 34717 describes placement of a branched endograft in the main iliac artery and its major branches on one side of the body performed during an aortoiliac endograft procedure to repair a rupture or other defect. The service includes sizing and device selection, selective catheterization on the same side, all endograft extensions, angioplasty or stenting, and all RS&I when performed. This code is reported in conjunction with the code for the primary aortoiliac endograft procedure.
-
Service type: Endovascular branched iliac endograft placement as an adjunct to an aortoiliac endograft procedure
-
Typical site of service: Hospital inpatient or hospital outpatient interventional suite or hybrid operating room
Clinical & Coding Specifications
Clinical Context
A 72-year-old male with a history of hypertension and peripheral arterial disease presents with a symptomatic ruptured left common iliac artery aneurysm identified on CT angiography. The vascular surgery team proceeds with endovascular repair under general anesthesia. During planned aortoiliac endograft deployment to exclude the aneurysm, the operator encounters a large left-sided iliac bifurcation defect requiring placement of a branched iliac endograft to preserve flow into the internal iliac artery. The procedure includes device sizing and selection, ipsilateral selective catheterization of the internal iliac branch, deployment of the branched iliac limb, any necessary extension grafts, and adjunctive angioplasty or stent placement to secure seal and branch patency. Completion angiography and all radiology supervision and interpretation are performed. The branched iliac endograft is reported with 34717 in conjunction with the primary aortoiliac endograft code. Typical perioperative workflow includes preoperative imaging review and device planning, hybrid operating room setup, fluoroscopic-guided endovascular access (commonly femoral), catheter-based selective branch cannulation, deployment of main and branched components, adjunctive ballooning or stenting, completion angiography, and postprocedure vascular monitoring. Typical site of service is an inpatient or outpatient hospital-based endovascular suite or hybrid operating room. Service type is endovascular surgical repair (open vs. percutaneous endograft deployment), specifically a branched iliac endograft placement performed in conjunction with a primary aortoiliac endograft procedure.
