CPT 35583: Femoral to Popliteal Bypass Using Saphenous Vein

CPT code 35583 represents an open vascular surgical procedure: a femoral-to-popliteal bypass using the patient’s saphenous vein to bypass femoral artery obstruction and restore lower-extremity perfusion. This code captures a high-acuity revascularization service used in the management of advanced peripheral arterial disease and critical limb ischemia. Nationally, surgical bypass remains an important therapeutic option when endovascular interventions are not feasible or have failed, with implications for hospital resource use, surgical specialty billing, and post-operative care pathways.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical and billing-oriented overview of the procedure represented by this code, an explanation of typical sites of service, and what metrics are commonly evaluated around such procedures (e.g., utilization, setting of care, and related surgical quality considerations). The publication outlines benchmark concepts and policy-relevant context affecting coverage and reimbursement for open vascular bypass procedures, and it summarizes clinical indications and procedural scope to inform billing, coding reviews, and payer-provider discussions.

Billing Code Overview

CPT code 35583 describes a femoral to popliteal bypass using the patient's saphenous vein to bypass an arterial blockage in the femoral artery and restore blood flow to the lower extremity. This procedure is a surgical revascularization service that typically addresses peripheral arterial disease when less invasive endovascular options are unsuitable or have failed.

Service Type: Open vascular surgical bypass

Typical Site of Service: Inpatient or outpatient surgical setting, commonly performed in an operating room with vascular surgery capability

Clinical & Coding Specifications

Clinical Context

A 68-year-old male with a history of peripheral arterial disease, tobacco use, hypertension, and hyperlipidemia presents with progressive right lower-extremity claudication and rest pain. Noninvasive vascular studies and arterial duplex demonstrate a significant occlusive lesion of the superficial femoral artery with diminished distal popliteal runoff. After evaluation by vascular surgery, the patient is scheduled for an open femoral-to-popliteal bypass using the ipsilateral great saphenous vein as the conduit to restore inflow to the distal limb and relieve ischemic symptoms. The clinical workflow includes preoperative assessment (cardiac clearance, medication review, duplex/angiographic imaging), intraoperative harvesting of the saphenous vein, creation of the femoro-popliteal bypass graft under general or regional anesthesia, intraoperative assessment of graft flow, and postoperative monitoring in the recovery unit or surgical floor with vascular checks, wound care, anticoagulation management, and follow-up duplex surveillance.

`LT`	Left side	Use when the procedure is performed on the left lower extremity.
`59`	Distinct procedural service	Use when another service or procedure not normally reported together is performed and meets distinct procedural service criteria.
`50`	Bilateral procedure	Use when bilateral femoral-to-popliteal bypasses are performed during the same operative session.
`62`	Two surgeons	Use when two surgeons work together as primary surgeons performing distinct portions of the bypass.

`22`	Increased procedural services	Use when work required to perform the bypass is substantially greater than typically required (document rationale).
`52`	Reduced services	Use when the bypass is partially reduced or not completed as planned.
`53`	Discontinued procedure	Use when the bypass was started but discontinued due to extenuating circumstances.
`76`	(Not in provided list)	Data not available in the input.
