Summary & Overview

CPT 37290: Atherectomy for Tibial/Peroneal Occlusion

CPT code 37290 defines atherectomy, with angioplasty when performed, for complex occlusive lesions of an initial tibial or peroneal artery (anterior tibial, posterior tibial, or peroneal). This code captures comprehensive peripheral vascular intervention services including access, catheterization, lesion crossing, and imaging guidance, and applies to percutaneous or open approaches. Nationally, the code is relevant for limb salvage programs, peripheral arterial disease management, and payment policy for advanced endovascular techniques. Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and typical settings of care, discussions of payer coverage patterns and benchmarking metrics, and practical coding considerations tied to the complexity of tibial and peroneal occlusions. The publication summarizes utilization and reimbursement benchmarks, highlights recent policy developments affecting peripheral intervention coding and coverage, and situates CPT code 37290 within related procedure coding for lower-extremity revascularization. Intended for clinicians, coding professionals, and policy analysts, the content clarifies when CPT code 37290 is used and what stakeholders should consider when evaluating claims, coverage, and program design across major national payers.

Billing Code Overview

CPT code 37290 describes an atherectomy with angioplasty when performed for a complex occlusive lesion of an initial tibial or peroneal vessel (anterior tibial, posterior tibial, or peroneal artery). The procedure includes all access, catheterization, lesion crossing, and imaging guidance required to complete the intervention. The approach may be percutaneous or open.

Service type: Peripheral vascular intervention (endovascular/surgical limb revascularization)

Typical site of service: Hospital-based interventional radiology or vascular surgery suite; outpatient ambulatory surgery center or inpatient operating room, depending on patient acuity and procedural approach.

Clinical & Coding Specifications

Clinical Context

A 68-year-old patient with long-standing diabetes mellitus and peripheral arterial disease presents with rest pain and non-healing ischemic ulcer of the foot. Noninvasive testing and diagnostic angiography demonstrate a chronic total occlusion of the proximal anterior tibial artery with poor distal perfusion. The interventional vascular specialist performs a percutaneous atherectomy of the occluded tibial segment with adjunctive transluminal angioplasty and intraprocedural imaging guidance to restore inline flow to the foot. The workflow includes pre-procedure assessment (consent, labs, anticoagulation review), arterial access (commonly antegrade femoral or pedal access), catheterization and lesion crossing using wires and catheters, atherectomy device deployment in the tibial/peroneal vessel, adjunctive balloon angioplasty as needed, completion angiography to document patency, hemostasis, and post-procedure monitoring for access site and limb perfusion changes.

`24`

Taxonomy Code	Specialty	Notes
`208G00000X`	Vascular Surgery	Primary specialty performing peripheral endovascular procedures including tibial atherectomy.
`2084P0800X`	Interventional Cardiology	Performs peripheral vascular interventions in some systems.
`207X00000X`	Interventional Radiology	Frequently performs image-guided atherectomy and angioplasty in tibial vessels.

ICD-10 Code	Description	Clinical Relevance
`I70.231`	Atherosclerosis of native arteries of extremities with ulceration, right leg	Peripheral arterial disease with ulceration is a common indication for tibial atherectomy to restore perfusion.
`I70.232`	Atherosclerosis of native arteries of extremities with ulceration, left leg	Same as above for left-sided disease prompting revascularization.
`I70.235`	Atherosclerosis of native arteries of extremities with gangrene, bilateral legs	Severe limb ischemia with tissue loss may necessitate endovascular atherectomy to salvage the limb.
`I70.239`	Atherosclerosis of native arteries of extremities with unspecified complication, unspecified leg	General PAD presentation warranting intervention.
`I73.9`	Peripheral vascular disease, unspecified	Broad diagnosis code used when procedural indication is peripheral arterial disease causing ischemic symptoms.
`E11.51`	Type 2 diabetes mellitus with diabetic peripheral angiopathy without gangrene	Diabetes-related PAD is a major risk factor and common comorbidity in patients undergoing tibial atherectomy.
`R02`	Gangrene, not elsewhere classified	Indicates tissue necrosis often due to critical limb ischemia, a direct clinical driver for revascularization procedures.
`L97.421`	Non-pressure chronic ulcer of left heel and midfoot with partial thickness skin loss	Ischemic foot ulcerations are frequent indications to perform tibial/peroneal interventions to improve wound healing.
