CPT® Code 75803

The CPT® Code 75803 refers to a specific radiological procedure known as lymphangiography, which is performed on both extremities (bilateral). This procedure involves the physician overseeing and interpreting the imaging results obtained from the lymphatic system of the legs. Lymphangiography is utilized to visualize the lymphatic vessels, which are crucial for understanding various medical conditions related to the lymphatic system. During the procedure, a separate injection is made to facilitate the imaging process. The physician begins by cleansing the skin of the foot and injecting a blue indicator dye between the toes, allowing for the observation of the dye's spread into the small lymph vessels. This initial phase typically takes between 15 to 30 minutes. Once the lymph vessels are adequately delineated, 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 this vessel to inject contrast media, which enhances the visibility of the lymphatic structures. Radiographs are taken over a period of 1 to 2 hours as the contrast material travels through the lymph vessels, allowing for detailed imaging. The physician subsequently reviews these radiographs and provides a comprehensive written interpretation of the findings. It is important to note that CPT® Code 75801 should be used for unilateral lymphangiography of the extremities, while CPT® Code 75803 is specifically designated for bilateral procedures.
