CPT code 37263: Leg angioplasty, simple lesion, first vessel2026 Medicare rate & RVUs

Medicare pays $5,429.65 for 37263 nationally in the office and $356.05 in a hospital or facility. Local office rates run $4,679.54–$7,688.24.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 37263 covers

Code 37263 represents endovascular balloon angioplasty to restore flow through a femoral or popliteal artery when the treated lesion meets CPT’s simple-lesion criteria and this is the first treated vessel. Vascular surgeons, interventional radiologists, and interventional cardiologists commonly perform the procedure in a hospital catheterization laboratory or angiography suite for peripheral arterial disease. Stent placement or atherectomy changes the applicable treatment code family.

Report the code for the first qualifying vessel, not for each balloon inflation. For another treated vessel, use the additional-vessel code when appropriate; choose a complex-lesion code when the lesion meets that category’s criteria. Document the target artery, laterality, lesion characteristics supporting the simple classification, treatment performed, and vessels treated. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and others at 50%. Modifier 50 for bilateral treatment is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
