Summary & Overview
CPT 37294: Tibial/Peroneal Revascularization with Stent and Atherectomy
CPT code 37294 denotes combined stent placement and atherectomy, with possible angioplasty, for complex occlusive lesions in an initial tibial or peroneal artery (including anterior tibial, posterior tibial, and peroneal arteries). This technically complex revascularization procedure is used in limb-salvage and critical limb ischemia care and has national relevance due to rising peripheral artery disease prevalence and evolving endovascular techniques. Key payers addressed in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise briefing on the clinical context and service characteristics of CPT code 37294, coverage and coding considerations across major payers, typical sites of service and service line placement, and related code groupings. The publication summarizes expected utilization scenarios and highlights policy and billing topics that affect reimbursement and claim adjudication for complex tibial/peroneal revascularization. Data not available in the input will be identified as such in specific sections. The goal is to provide clinicians, coders, and policy staff with an accessible national summary of what CPT code 37294 represents and where to focus attention for coding and coverage inquiries.
Billing Code Overview
CPT code 37294 describes revascularization of a complex occlusive lesion in an initial tibial or peroneal vessel that includes both stent placement and atherectomy (plaque removal). The procedure may also include angioplasty as part of the revascularization strategy. The service covers all necessary access, catheterization, lesion crossing, and imaging guidance required to complete the intervention. The approach may be open or percutaneous.
-
Service type: Endovascular revascularization with combined stent placement and atherectomy for a complex tibial/peroneal lesion
-
Typical site of service: Hospital-based vascular/interventional suite or ambulatory surgical center; may also occur in an operating room for open approaches
Clinical & Coding Specifications
Clinical Context
A typical patient is a 68-year-old with diabetes mellitus and long-standing peripheral arterial disease who presents with rest pain and non-healing forefoot ulceration. Noninvasive testing (ABI, duplex ultrasound) and diagnostic angiography demonstrate an occlusive, calcified lesion in the tibial-peroneal trunk or an occlusion involving the proximal posterior tibial artery. After assessment by the vascular specialist, the patient proceeds to the interventional suite for endovascular revascularization.
The procedure includes arterial access (commonly antegrade common femoral or antegrade popliteal), catheterization and selective angiography of the tibial/peroneal vessels, lesion crossing with guidewires and support catheters, atherectomy to debulk plaque, stent placement to scaffold the treated segment, and optional balloon angioplasty for vessel preparation or post-dilatation. Intraprocedural imaging (digital subtraction angiography, fluoroscopy) and hemostasis management (closure device or manual compression) are part of the episode of care. The typical site of service is an inpatient vascular/interventional radiology suite or an outpatient ambulatory surgery center or hospital-based cath lab, depending on comorbid conditions and expected postprocedural monitoring needs.
Care workflow includes pre-procedure informed consent and cardiac/renal risk assessment, peri-procedural anticoagulation management, device selection (atherectomy catheter type, stent type/size), documentation of lesion complexity (occlusion, length, calcification), and postprocedural monitoring for access-site complications, distal perfusion, and renal function. Discharge planning addresses wound care, antiplatelet therapy, and follow-up vascular imaging or clinic visit.
