Endovascular therapy
About 37212: Initial venous thrombolysis treatment
Reports catheter-directed thrombolytic infusion in the venous system on the initial treatment day, such as treatment of an extensive acute venous thrombosis.
This code represents the initial treatment day for delivering a thrombolytic drug into a vein through a catheter to dissolve a clot. A typical situation is catheter-directed treatment of extensive acute iliofemoral deep vein thrombosis. Interventional radiologists, vascular surgeons, and other physicians who perform endovascular procedures may provide the service, generally in a hospital or other facility. The code includes radiological supervision and interpretation associated with the thrombolytic treatment.
Report 37212 for the initial treatment day; continued treatment on a later day and stopping therapy with catheter removal are represented by separate codes in this family. Documentation should identify the venous target, the thrombus and clinical indication, the infusion performed, and that this is the initial treatment day. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 applies to bilateral reporting, paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

Which code applies when thrombolytic treatment is stopped and the catheter is removed?
Use 37214 for cessation of thrombolytic therapy with catheter removal, rather than reporting another initial-day service.
Is radiological supervision and interpretation included?
Yes. The code includes radiological supervision and interpretation associated with the venous thrombolytic treatment.
What documentation supports reporting 37212?
