CPT® Code 37244

Vascular embolization or occlusion, inclusive of all radiological supervision and interpretation, intraprocedural roadmapping, and imaging guidance necessary to complete the intervention; for arterial or venous hemorrhage or lymphatic extravasation

The CPT® Code 37244 refers to a medical procedure known as vascular embolization or occlusion, which is performed to manage conditions such as arterial or venous hemorrhage and lymphatic extravasation. This procedure is critical in controlling excessive bleeding or fluid leakage from lymphatic vessels. During the intervention, the physician utilizes imaging techniques to guide the procedure, ensuring precise targeting of the affected blood or lymphatic vessels. The process begins with obtaining initial angiograms, which are imaging studies that help identify the specific vessels involved in the hemorrhage or extravasation. The physician then selects an appropriate access point to reach the targeted vessel. Following this, a series of steps involving the insertion of an introducer sheath, guide wire, and catheter are performed to facilitate the delivery of occlusive or embolic materials. These materials, which may include substances like viscous collagen agents, polyvinyl alcohol particles, or ethiodized oil, are introduced to effectively block the flow of blood or lymph, thereby addressing the underlying issue. The procedure is comprehensive, incorporating all necessary radiological supervision and interpretation, as well as intraprocedural roadmapping and imaging guidance to ensure successful intervention and patient safety.
