Summary & Overview
CPT 35881: Lower Extremity Bypass Graft Vein Segment Replacement
CPT code 35881 represents a vascular surgical procedure that uses a harvested vein segment to replace a narrowed portion of a lower extremity arterial bypass graft. This revision or repair is clinically significant because it addresses graft stenosis or graft failure, which can threaten limb perfusion and increase the risk of limb loss. Nationwide, such procedures are performed across inpatient and outpatient surgical settings and are relevant to hospitals, vascular surgeons, and payers managing complex peripheral arterial disease care.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical context, typical sites of service, and the types of metrics and policy issues commonly associated with reimbursement and utilization for graft revision procedures. The publication outlines benchmarks and payment considerations, highlights typical clinical indications for performing a vein-segment replacement in a lower extremity bypass graft, and summarizes common payer coverage patterns and claims considerations. It also identifies areas where additional coding specificity or documentation can affect coverage and claims processing.
Data not available in the input is noted where applicable; the summary focuses on nationally relevant clinical and billing context rather than state-specific rules.
Billing Code Overview
CPT code 35881 describes a surgical procedure in which a harvested vein segment is used to replace a narrowed portion of a lower extremity arterial bypass graft. This procedure is a vascular surgical revision aiming to restore or improve blood flow in a previously placed arterial bypass within the leg.
Service Type: Vascular surgical graft revision / bypass graft repair
Typical Site of Service: Hospital operating room (inpatient or outpatient surgical setting) or ambulatory surgery center, depending on patient condition and clinical need.
Clinical & Coding Specifications
Clinical Context
A 68-year-old male with a history of peripheral arterial disease and prior femoropopliteal bypass presents with progressive rest pain and a nonhealing ulcer on the lateral foot. Duplex ultrasound and CT angiography demonstrate a focal stenosis and venous segment degeneration within the existing lower extremity bypass graft. The vascular surgery team schedules an operative reintervention under general anesthesia in an ambulatory surgery center or hospital operating room. Intraoperatively the surgeon harvests an autologous vein segment (commonly the contralateral great saphenous vein or an arm vein), excises the narrowed portion of the existing graft, and interposes the harvested vein as a patch or segmental bypass conduit to restore adequate inflow and distal perfusion. Postoperative workflow includes surgical site monitoring, anticoagulation management, vascular ultrasound surveillance prior to discharge, and documentation of graft revision technique, vein harvest site, laterality, and any complications. Typical sites of service include the hospital operating room or ambulatory surgical center for an open vascular bypass revision.
