What 37287 covers
This add-on code covers stent placement in each additional peripheral artery treated as part of a complex endovascular revascularization. It is used when the intervention extends beyond the first qualifying vessel and the documented lesion treatment supports the complex stenting category. Vascular surgeons and interventional radiologists commonly perform these procedures in an angiography suite or hospital operating room for peripheral arterial disease.
Report 37287 only with an appropriate primary revascularization procedure; it is not a stand-alone service. The operative report should identify the treated vessels, the stent placement in each additional vessel, and the clinical and procedural details supporting complex rather than simple treatment. When the procedure is bilateral, modifier 50 is paid at 150%. CMS places payment for this add-on within the primary procedure’s global period.
