Headline: New CPT code 0620T defines endovascular venous arterialization for limb salvage

Lead: CPT code 0620T captures endovascular venous arterialization of the tibial or peroneal vein with stent placement to direct oxygenated blood from a blocked artery into a vein, a limb-salvage technique for chronic limb–threatening ischemia.

CPT code 0620T represents a specialized endovascular procedure that allows retrograde arterial perfusion to ischemic distal tissues by creating an arterial-to-venous conduit and placing stents. This intervention matters nationally as chronic limb–threatening ischemia is associated with high amputation risk and substantial downstream costs; a dedicated CPT code enables clearer clinical documentation and payer adjudication for a complex revascularization technique.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The code includes vascular access, catheterization, and imaging guidance as part of the reported service.

Readers will find a concise overview of the clinical context and service setting, summaries of coverage and reimbursement considerations across major national payers, and benchmarks for billing and coding practice where available. The publication also outlines common billing modifiers and identifies areas where input or additional policy guidance from payers may affect coverage. Data not available in the input is noted where applicable.
