Summary & Overview
CPT 33880: Endovascular Repair of Thoracic Aorta Covering Left Subclavian Origin
CPT code 33880 represents an endovascular thoracic aortic repair in which an endograft is delivered and deployed to cover the origin of the left subclavian artery, with possible extension into the aortic arch, ascending aorta, or downward toward the celiac artery. This complex vascular procedure is a key treatment option for thoracic aortic disease and carries significant implications for device selection, imaging resources, and perioperative management nationwide. Major payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise synthesis of clinical context, typical sites of service, and the components of the procedure that are bundled into the code. The publication provides benchmarking insights on coverage and reimbursement patterns, highlights policy and coding considerations relevant to hospital and interventional teams, and summarizes common modifiers encountered in claims for complex endovascular aortic work. Data limitations are noted where input information was not provided. This summary is intended to inform clinicians, coding professionals, and payers about the scope of services represented by CPT code 33880 and the practical implications for billing and authorization workflows.
Billing Code Overview
CPT code 33880 describes an endovascular repair of the thoracic aorta using an endograft or stent graft that covers the origin of the left subclavian artery. The procedure includes delivery and deployment of the graft and may extend upward into the aortic arch or ascending aorta and downward toward the celiac artery as clinically needed. The service also encompasses preprocedure sizing and device selection, nonselective catheterization, and all imaging guidance and interpretation required to complete the repair.
-
Service type: Endovascular thoracic aortic repair (endograft/stent graft placement)
-
Typical site of service: Hospital operating room or catheterization/interventional radiology suite with full imaging capabilities
Clinical & Coding Specifications
Clinical Context
A 72-year-old male with a 6.0-cm descending thoracic aortic aneurysm involving the origin of the left subclavian artery presents for endovascular repair. Preoperative workup includes CT angiography with sizing of the aortic arch and branch vessels, cardiopulmonary evaluation, and vascular lab testing. In the hybrid endovascular suite, under general anesthesia, the vascular surgery or interventional cardiology team obtains femoral arterial access, performs nonselective catheterization and angiographic imaging, selects an appropriately sized thoracic endograft, advances the device via guidewire, and deploys the stent graft to intentionally cover the origin of the left subclavian artery to achieve an adequate proximal seal. Intraoperative imaging (fluoroscopy, digital subtraction angiography) and interpretation are included. If necessary, the repair is extended proximally into the arch or ascending aorta or distally toward the visceral segment (celiac axis) by additional graft extensions. Postprocedure care includes ICU monitoring, neurovascular assessment for left arm ischemia and posterior circulation symptoms, and surveillance imaging before discharge and at scheduled follow-up intervals.
