About 37188: Repeat venous mechanical thrombectomy
Reports repeat catheter-based mechanical removal of venous thrombus during the same session as primary venous thrombectomy when further treatment is performed.
This code describes repeat catheter-based mechanical removal of thrombus from a vein during the same session as the primary venous thrombectomy. It is used in endovascular treatment of venous clot, such as deep vein thrombosis, when the physician performs repeat thrombectomy after the primary treatment. Interventional radiologists, vascular surgeons, and other physicians with appropriate endovascular training commonly perform the service in a hospital or other procedural facility. Fluoroscopic guidance and intraprocedural thrombolytic injections are part of the service.
Report 37188 as an add-on to 37187, not as the primary venous thrombectomy code. The procedure report should identify the treated vein or veins, the primary thrombectomy, and the repeat treatment performed during that same session. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For bilateral treatment, modifier 50 is paid at 150%. An assistant at surgery is not paid; co-surgeons are permitted, while team surgery is not permitted.
