CPT® Code 75805

The CPT® Code 75805 refers to the procedure known as lymphangiography, specifically focusing on the pelvic and abdominal regions, performed unilaterally. This procedure involves the use of radiological techniques to visualize the lymphatic system, which is crucial for diagnosing various conditions related to lymphatic flow and function. During lymphangiography, a physician conducts radiological supervision and interpretation, ensuring that the imaging process is accurately monitored and assessed. The procedure begins with the preparation of the patient, where the skin of the foot is cleansed, and a blue indicator dye is injected between the toes. This dye serves as a tracer, allowing the physician to observe its movement through the lymphatic vessels. The observation period typically lasts between 15 to 30 minutes, during which the physician assesses the spread of the dye into the small lymph vessels of the foot. Once adequate delineation of the lymph vessels is achieved, a local anesthetic is administered, followed by an incision to expose one of the larger lymph vessels. A needle or catheter is then inserted into the exposed vessel to inject contrast media, which enhances the visibility of the lymphatic structures during imaging. Radiographs are subsequently obtained, capturing detailed images of the lymph vessels in the abdomen and/or pelvis over a duration of 1 to 2 hours. The physician concludes the procedure by reviewing the radiographs and providing a comprehensive written interpretation of the findings. It is important to note that for a unilateral lymphangiogram of the abdomen or pelvis, the appropriate code to use is 75805, while 75807 should be utilized if a bilateral imaging procedure is conducted.
