CPT® Code 75716

The procedure described by CPT® Code 75716 refers to angiography of the extremities, specifically performed bilaterally, which involves the use of radiological supervision and interpretation. Angiography is a diagnostic imaging technique that allows healthcare professionals to visualize the blood vessels and assess the integrity of the arterial walls in the extremities. This is achieved through the injection of a radiopaque contrast medium, which enhances the visibility of the blood vessels during imaging. The procedure typically employs fluoroscopy, a real-time imaging technique that provides continuous X-ray images, allowing for the observation of blood flow as the contrast medium travels through the arteries.

For lower extremity angiography, the procedure begins with the insertion of a large bore needle into the femoral artery located in the groin. A guidewire is then introduced through this needle, followed by the advancement of a catheter over the guidewire to the targeted area for examination. Once positioned, a contrast dye is injected to visualize the blood flow through the leg down to the foot. In the case of upper extremity angiography, the needle may be inserted into either the radial artery at the wrist or the brachial artery in the upper arm, with a similar process of guidewire and catheter advancement followed by dye injection. The real-time imaging allows for the assessment of blood flow dynamics, and the resulting images are recorded for further analysis or comparison with previous studies. It is important to note that CPT® Code 75716 specifically indicates that the procedure is performed on both sides of the body, either both arms or both legs, and includes the radiologist's supervision, interpretation of the findings, and the generation of a written report, distinguishing it from related codes that pertain to unilateral procedures.
