Summary & Overview
CPT 34718: Branched Iliac Endograft Placement, Unilateral
CPT code 34718 represents a unilateral branched endograft placement in the main iliac artery and its major branches to repair a rupture or other arterial defect. As an endovascular vascular repair add-on reported alongside a primary procedure, this code captures complex device selection, selective same-side catheterization, endograft extensions, and any adjunctive angioplasty or stenting performed during the same operative episode. Nationwide, accurate capture of CPT code 34718 is important for tracking utilization of advanced endovascular technologies and for ensuring appropriate facility and physician reimbursement for high-complexity vascular interventions.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical intent and service setting, common billing modifiers (listed separately), and guidance on how the code is reported relative to primary procedures. The publication also outlines expected use cases, typical site-of-service considerations (hospital operating room or endovascular suite, inpatient or outpatient hospital-based care), and the clinical context of branched iliac endografts for arterial rupture or major branch involvement.
This piece is designed to inform coding managers, billing teams, and clinical leaders about the code’s purpose, reporting conventions, and where to look for payer-specific policies and coverage criteria. Data not available in the input includes specific payer reimbursement rates, associated taxonomies, and ICD-10 diagnosis pairings.
Billing Code Overview
CPT code 34718 describes placement of a branched endograft in the main iliac artery and its major branches on one side of the body to repair a rupture or other defect. The procedure includes sizing and device selection, selective catheterization on the same side, all endograft extensions, and any angioplasty or stenting performed as part of the same operation. Reporting of CPT code 34718 is intended to be done in conjunction with the code for the primary procedure.
Service type: Endovascular vascular repair procedure involving branched iliac artery endograft placement
Typical site of service: Hospital operating room or endovascular suite (inpatient or outpatient hospital-based setting)
Clinical & Coding Specifications
Clinical Context
A 72-year-old male with a history of hypertension and peripheral arterial disease presents emergently with left-sided iliac artery rupture related to an aneurysmal degeneration of the common iliac artery. After initial resuscitation and cross-sectional imaging confirming active extravasation and focal disruption of the left common iliac artery and involvement of the internal iliac branches, the vascular surgery team elects an endovascular repair. In the hybrid vascular suite the surgeon performs angiography, selects and sizes a branched iliac endograft, and deploys a branched endograft into the left main iliac artery with catheterization of the internal iliac branch on the same side, plus any necessary distal extensions, angioplasty, or stenting. The procedure includes device selection, selective catheterization on the ipsilateral side, all endograft extensions, adjunctive angioplasty/stenting, and radiology supervision and interpretation as indicated. Typical postoperative workflow includes vascular access closure, immediate angiographic confirmation of exclusion of the rupture, hemodynamic monitoring in a post-anesthesia care unit or intensive care unit depending on stability, and follow-up CT angiography within 24–72 hours to confirm graft position and perfusion of pelvic branches.
