What 37284 covers
This code describes endovascular stent treatment of an initial tibial or peroneal vein as part of deep vein revascularization. The service may include angioplasty in that same vein when performed. It is used in procedures such as deep vein arterialization for limb-threatening ischemia, generally performed by an interventional radiologist, vascular surgeon, or other physician with endovascular expertise in a hospital setting.
Report this code for the initial treated vein when the procedure meets billing code’s straightforward criteria; use the applicable complex code when those criteria are met instead. Documentation should identify the treated vein, the stent placement, any same-vein angioplasty, and the basis for classifying the intervention as straightforward. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued is paid in full and the others at 50%. Modifier 50 is paid at 150% for bilateral procedures. Assistant-at-surgery payment requires medical-necessity documentation; co-surgeons and team surgery are not permitted.
