CPT® Code 75894

Transcatheter therapy, specifically embolization, is a minimally invasive procedure that involves the intentional occlusion of blood vessels to manage various medical conditions. This procedure is performed under radiological supervision, which entails the use of imaging techniques to guide the intervention and ensure accurate placement of the catheter. The primary goal of embolization is to either permanently or temporarily reduce or eliminate blood flow to a specific target area within the central nervous system, or in the head or neck region. This therapeutic approach can be employed for both curative and palliative purposes, particularly in cases of hemorrhage resulting from trauma, as well as in the treatment of neoplasms and vascular anomalies that may be congenital or acquired. During the procedure, a healthcare professional accesses the appropriate blood vessel through a needle puncture, followed by the insertion of a guidewire. This guidewire is carefully threaded to the designated embolization site, utilizing fluoroscopic guidance to ensure precision. Once the guidewire is in place, a catheter is advanced over it to reach the targeted area, after which the guidewire is removed. To confirm the correct positioning of the catheter, a radiopaque contrast medium is injected, and X-ray imaging is performed. The actual embolization is then executed using various methods, which may include the application of chemotherapeutic agents, radiofrequency energy, metallic coils, detachable balloons, autologous clots, absorbable gelatin sponges, or microfibrillar collagen. Upon completion of the procedure, the catheter is removed, and the code 75894 is utilized to report the radiological supervision and interpretation of the transcatheter embolization procedure, including the review of images obtained and the documentation of findings in a written report.
