In simple words: This procedure involves injecting a substance to block abnormal blood vessels or vascular channels. The doctor uses imaging technology to guide a catheter (thin tube) to the targeted blood vessels. A special dye is injected to visualize blood flow, allowing for precise blockage of the vessels. This can be performed for various reasons, like treating tumors or other abnormalities by cutting off their blood supply.

This code represents the physician's supervision and interpretation of a transcatheter embolization procedure. Embolization is a technique used to block blood flow to a specific area, often to treat tumors, vascular malformations, or bleeding. This code includes imaging guidance using fluoroscopy, contrast injection, vessel measurement, and completion angiography. Note: This code is not to be reported with certain other vascular embolization codes (36475, 36476, 36478, 36479, 36836, 36837, 37241, 37242, 37243, 37244) as the supervision and interpretation are included in those codes.

Example 1: A patient presents with a uterine fibroid causing significant bleeding. Uterine artery embolization is performed under radiological supervision and interpretation (75894) to block blood flow to the fibroid., A patient with a liver tumor undergoes transcatheter arterial chemoembolization. Code 75894 is reported for the radiological supervision and interpretation of the embolization procedure used to deliver chemotherapy directly to the tumor., A patient experiences acute gastrointestinal bleeding. Embolization is performed to stop the bleeding, and code 75894 is used to report the radiologist's supervision and interpretation of the embolization procedure.

Documentation should include details of the embolization procedure, including the approach, the target vessel, the embolic agent used, and the imaging guidance provided. Reports should clearly distinguish between diagnostic and therapeutic procedures and support the medical necessity of the embolization.
