About 37191: Endovascular vena cava filter placement
Reports catheter-based placement of a vena cava filter, typically to reduce pulmonary embolism risk when anticoagulation is unsuitable or insufficient.
An interventional radiologist, vascular surgeon, or other qualified proceduralist advances a filter through venous access into the vena cava under imaging guidance. Placement commonly takes place in a hospital interventional radiology or catheterization suite. The service covers the endovascular placement, including the access and imaging work integral to deploying the filter. Clinical circumstances may include venous thromboembolism when anticoagulation cannot be used or has not adequately prevented embolic risk.
Select this code for filter placement, not for repositioning an existing filter or retrieving one. The record should support the clinical indication and document the access, imaging-guided procedure, and filter deployment. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate for this service. Medicare does not pay an assistant at surgery for this code, and co-surgeon and team-surgery billing are not permitted.
