CPT code 37244: Vascular embolization, hemorrhage or lymphatic leak2026 Medicare rate & RVUs

What 37244 covers

An interventional radiologist or vascular specialist uses catheter-based techniques to block a bleeding artery or vein, or a leaking lymphatic vessel. Typical cases include embolization of a vessel responsible for gastrointestinal bleeding, control of pelvic arterial bleeding after trauma, or treatment of a lymphatic leak. The procedure is generally performed in a hospital angiography or interventional radiology suite. The code includes the radiological supervision and interpretation, intraprocedural roadmapping, and imaging guidance needed to complete the embolization.

Select this code when the treatment addresses hemorrhage or a lymphatic leak; the indication distinguishes it from embolization for other purposes. The procedure report should identify the bleeding or leaking site, target vessel or vessels, clinical indication, and embolization performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. 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. Assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.
