The CPT® Code 37241 refers to a specific medical procedure known as vascular embolization or occlusion. This procedure is performed to block or close off a blood vessel, particularly in cases involving venous conditions that are not related to hemorrhage. The conditions that may necessitate this intervention include congenital or acquired venous malformations, venous and capillary hemangiomas, varices, and varicoceles. The procedure is comprehensive, as it includes all necessary radiological supervision and interpretation, as well as intraprocedural roadmapping and imaging guidance to ensure the intervention is completed successfully. The use of imaging techniques, such as angiography, is critical in identifying the affected blood vessel and determining the most effective approach for occlusion or embolization. This procedure is essential in managing various vascular abnormalities, providing a minimally invasive option to treat conditions that could lead to complications if left untreated.

The procedure described by CPT® Code 37241 is indicated for various venous conditions that require intervention. These indications include:
The procedure for vascular embolization or occlusion as described by CPT® Code 37241 involves several critical steps to ensure successful intervention. The first step is the identification of the affected blood vessel, which is accomplished using angiography. This imaging technique allows the physician to visualize the vascular structure and determine the most appropriate access site for the procedure. Once the site is selected, the physician makes a small incision to nick the skin over the chosen blood vessel and inserts an introducer sheath. This sheath serves as a conduit for further instruments.
Next, a guide wire is introduced through the sheath and carefully advanced to the planned site of occlusion or embolization. This guide wire is essential for navigating the vascular system and ensuring accurate placement of the subsequent catheter. After the guide wire is in position, a catheter is advanced over it, and the guide wire is then withdrawn, leaving the catheter in place for the next steps of the procedure.
Following catheter placement, angiography is performed again to delineate the vasculature at the site of the vessel malformation, arteriovenous fistula, aneurysm, or pseudoaneurysm. This imaging is crucial for confirming the exact location and extent of the vascular abnormality. Once the site is clearly visualized, occlusive or embolic material is introduced through the catheter. The materials used may include a viscous collagen agent, polyvinyl alcohol particles, or ethiodized oil, all of which are designed to effectively block the blood flow in the targeted vessel.
After the occlusive or embolic material is administered, additional angiograms are obtained to verify that the treated blood vessel is completely occluded. This step is vital to ensure the success of the procedure and to confirm that the intended therapeutic effect has been achieved. Upon completion of the embolization or occlusion, the catheter is carefully removed, and pressure is applied to the vascular access site to control any potential bleeding, ensuring patient safety and minimizing complications.
After the vascular embolization or occlusion procedure, patients are typically monitored for any immediate complications, such as bleeding or adverse reactions to the embolic materials used. The healthcare team will assess the vascular access site to ensure that hemostasis is achieved. Patients may be advised to rest and avoid strenuous activities for a specified period to facilitate recovery. Follow-up imaging may be scheduled to evaluate the long-term effectiveness of the embolization and to monitor for any potential recurrence of the vascular condition. It is essential for patients to adhere to any post-procedure instructions provided by their healthcare provider to ensure optimal recovery and outcomes.
