2025 CPT code 37241
(Active) Effective Date: N/A Revision Date: N/A Surgery - Vascular Embolization and Occlusion Surgery Feed
Endovascular embolization or occlusion of veins, excluding hemorrhage or hemodialysis access.
Modifiers may be applicable depending on the circumstances of the procedure (e.g., modifier 59 for multiple procedures or distinct locations).
Medical necessity is established by the presence of symptomatic venous malformations, varices, or varicoceles causing pain, swelling, or other clinically significant symptoms unresponsive to conservative management.Documentation must support the need for the intervention.
The physician prepares the patient, administers anesthesia (if necessary), performs the percutaneous access to the vein, uses a guidewire and catheter to deliver embolic materials (e.g., coils, balloons, ethanol, collagen), and achieves hemostasis.Radiologic supervision and interpretation are included.
In simple words: The doctor blocks blood flow in a vein using a catheter and special materials. This is done for problems like vein malformations or varicose veins, but not for bleeding.
This CPT code reports endovascular embolization or occlusion procedures performed on veins for conditions other than hemorrhage or hemodialysis access.Examples include embolization of venous malformations, capillary hemangiomas, varicoceles, and visceral varices. The code encompasses all associated radiological supervision and interpretation, intra-procedural guidance and road-mapping, and imaging necessary to document procedure completion.Diagnostic angiography and catheter placement are separately reported if performed.
Example 1: Embolization of a venous malformation in the leg causing pain and swelling., Embolization of varicoceles in a male patient causing discomfort and infertility concerns., Embolization of visceral varices in a patient with portal hypertension.
Pre-procedure imaging (e.g., ultrasound, CT), procedural notes detailing catheterization approach, embolic agent used, volume administered, and angiographic images demonstrating occlusion. Post-procedure imaging to confirm successful embolization. Patient history, physical examination findings documenting the indication for the procedure.
** This code should only be reported once per surgical field.Multiple codes can be used if multiple surgical fields are involved, with appropriate modifier usage (e.g. modifier 59).
