CPT code 37275: Leg artery revascularization, straightforward lesion, initial vessel2026 Medicare rate & RVUs

Medicare pays $10,275.79 for 37275 nationally in the office and $501.35 in a hospital or facility. Local office rates run $8,849.87–$14,619.75.

What 37275 covers

An endovascular specialist treats atherosclerotic narrowing or blockage in a femoral or popliteal artery, often for peripheral artery disease causing claudication or limb-threatening ischemia. Through catheter-based access, the operator removes plaque with atherectomy and places a stent in the initial treated vessel; balloon angioplasty in that vessel is included when performed. These procedures are commonly done in a hospital angiography suite by vascular surgeons, interventional radiologists, or cardiologists who perform peripheral interventions.

Report this code for the initial treated vessel when the lesion meets the CPT straightforward category and both atherectomy and stent placement are performed. Use the corresponding code for a complex lesion or an additional vessel when appropriate. Document the treated artery, lesion characteristics, and procedures performed. Same-day preoperative and postoperative care is included in the 0-day global period. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 results in payment at 150% for bilateral reporting. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

37276Peripheral revascularizationSimple, each additional vessel

This code is for the initial vessel. Code 37276 represents an additional vessel treated with the same straightforward stent-and-atherectomy approach.

37277Peripheral revascularizationComplex, initial vessel

Both codes include stent placement and atherectomy. Choose 37277 when the lesion meets the CPT complex category rather than the straightforward category.

37271AtherectomyStraightforward, initial vessel

Code 37271 describes straightforward atherectomy treatment without stent placement; this code includes both atherectomy and stenting.

37267Arterial stentingSimple lesion, initial vessel

Code 37267 describes straightforward stent treatment without atherectomy; this code includes both stent placement and atherectomy.
