CPT 34832: Open Aorto–Bifemoral Repair After Failed Endovascular Aortic Repair
CPT code 34832 captures an open aorto–bifemoral repair performed after an unsuccessful endovascular repair of an infrarenal aortic aneurysm or dissection. This code is used for cases where conversion to an open abdominal or retroperitoneal approach is necessary to place an aorto–bifemoral prosthesis and to address trauma from the failed endovascular procedure. Nationally, these conversions are clinically significant because they represent high-acuity, resource-intensive interventions with implications for surgical teams, hospital resource use, and payer coverage policies.
Key payers in the review include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the code’s clinical context, typical site of service, and common billing modifiers. The publication summarizes payer coverage considerations, expected care settings, and operational implications for hospitals and vascular surgery programs. It also outlines areas where policy updates or clarifications commonly arise related to conversions from endovascular to open repair.
This summary is intended to inform coding and administrative staff, hospital financial leaders, and vascular surgery teams about the clinical scope of CPT code 34832, typical scenarios that trigger its use, and the payer landscape relevant to national practice.
Billing Code Overview
CPT code 34832 describes an open surgical repair performed after an unsuccessful endovascular repair of an infrarenal aortic aneurysm or dissection. The procedure involves an abdominal or retroperitoneal incision and placement of an aorto–bifemoral prosthesis to repair the infrarenal aorta, and includes repair of any associated trauma resulting from the failed endovascular attempt.
Service type: Open vascular surgery after failed endovascular aortic repair
Typical site of service: Inpatient hospital operating room, often via an abdominal or retroperitoneal approach for vascular surgical intervention.
Clinical & Coding Specifications
Clinical Context
A 72-year-old male with a known infrarenal abdominal aortic aneurysm previously treated with an endovascular aneurysm repair (EVAR) presents with persistent bleeding and device-related injury after attempted endovascular revision. The vascular surgery team evaluates the patient in the operating room after imaging demonstrates an unsuccessful endovascular repair with graft malposition and retroperitoneal hematoma. Through an open abdominal or retroperitoneal incision, the surgeon performs an aorto–bifemoral bypass graft to definitively repair the infrarenal aortic aneurysm and concurrent repair of arterial injury and retroperitoneal trauma resulting from the failed endovascular procedure. The intraoperative workflow includes exposure of the infrarenal aorta, proximal and distal control, removal or exclusion of damaged endograft components as necessary, placement of an aorto–bifemoral prosthesis, hemostasis, and repair of any associated vascular or visceral injuries. Postoperative care involves intensive monitoring for hemodynamic stability, graft perfusion to lower extremities, surveillance imaging as indicated, and management of comorbid conditions such as coronary artery disease and chronic kidney disease.

| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the procedure required substantially greater work than usual due to extensive repair of endograft-related trauma or complex reconstruction. |
