Summary & Overview
CPT 35560: Aorta-to-Renal Artery Bypass Using Vein Graft
CPT code 35560 denotes an open vascular bypass from the aorta to a renal artery using a vein graft to bypass a renal artery obstruction. This operation is a definitive revascularization approach for renal ischemia due to severe atherosclerotic or other obstructive disease and carries implications for renal function preservation and hypertension management. Nationally, the procedure is performed in hospital surgical suites for patients with critical renal artery stenosis or occlusion when endovascular therapy is unsuitable or has failed.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and the service classification for billing purposes. The publication summarizes benchmark considerations and common claim adjudication factors relevant to these payers and highlights policy and coding nuances that affect coverage and payment processes. Clinical implications, utilization drivers, and areas where documentation commonly affects reimbursement are presented to help billing, coding, and administrative teams understand when and how CPT code 35560 applies.

Billing Code Overview
CPT code 35560 describes a surgical procedure in which the provider bypasses a renal artery blockage by inserting a bypass graft that connects the aorta to a portion of the renal artery using a vein graft. This procedure restores renal blood flow by creating an alternate blood supply route around a diseased or obstructed renal artery.
Service type: Open vascular bypass surgery of the renal artery using a vein graft.
Typical site of service: Operating room (inpatient or outpatient surgical setting), commonly performed in a hospital surgical suite.
Clinical & Coding Specifications
Clinical Context
A typical patient is an older adult with progressive renovascular hypertension or symptomatic renal artery stenosis due to atherosclerotic occlusive disease. The patient presents with refractory hypertension despite multi‑drug therapy, declining renal function, or recurrent flash pulmonary edema. Workup includes renal duplex ultrasound, CT angiography or MR angiography demonstrating significant ostial or proximal renal artery occlusion not amenable to endovascular stenting due to lesion anatomy, heavy calcification, or prior failed angioplasty.
The multidisciplinary clinical workflow begins with vascular surgery or transplant/vascular medicine consultation. Preoperative evaluation includes cardiac risk assessment, renal function optimization, and medication management. In the operating room under general anesthesia, the surgeon exposes the infrarenal aorta and affected renal artery; a segment of autologous saphenous vein or prosthetic graft is harvested and an aorto‑renal bypass is constructed to restore renal perfusion. Intraoperative angiography or Doppler confirms graft patency. Postoperative care includes ICU or monitored bed for hemodynamic monitoring, renal function surveillance, antiplatelet therapy as indicated, and discharge planning with blood pressure follow‑up and imaging surveillance of the bypass graft.
