Endovascular revascularization
About 37278: Complex femoral-popliteal stent and atherectomy, additional artery
Reports stent placement with atherectomy in each additional complex femoral or popliteal artery treated during endovascular revascularization.
This add-on represents treatment of an additional femoral or popliteal artery with both atherectomy and stent placement when the intervention meets the complex classification. The service is typically performed by an interventional radiologist, vascular surgeon, or other physician qualified to perform endovascular lower-extremity revascularization in an angiography suite or operating room. Code selection follows the treated arterial territory, the intervention performed, whether the artery is classified as complex, and whether it is the first or an additional artery treated.
Report this code with the applicable primary revascularization code; 37277 represents the first complex femoral-popliteal artery treated with stenting and atherectomy. The operative report should identify each treated artery, the intervention performed, and the basis for complex classification. CMS treats this as an add-on paid within the primary procedure’s global period. When the procedure is bilateral and modifier 50 is reported, CMS pays 150% of the applicable amount.
