CPT® Code 75842

The CPT® Code 75842 refers to a specialized radiological procedure known as venography, specifically targeting the adrenal veins on both sides of the body. This procedure involves the use of radiopaque contrast medium, which is a substance that enhances the visibility of internal structures during imaging. The primary purpose of this venography is to evaluate the adrenal veins, which can be crucial in diagnosing various medical conditions such as blood clots, tumors, and hormonal imbalances. In particular, the procedure is often utilized to assess levels of aldosterone, a hormone that plays a significant role in regulating blood pressure and electrolyte balance. The process typically begins with the access of the femoral vein, usually through a large bore needle inserted in the groin area. A guidewire is then carefully threaded through the needle and advanced into the vena cava, allowing for precise positioning to visualize the adrenal veins. Following this, a catheter is inserted over the guidewire to reach the desired location, and the guidewire is subsequently removed. Blood samples may be collected during this procedure for further testing of aldosterone levels, especially if there are indications of abnormal hormone levels. After the contrast medium is injected through the catheter, x-ray images of the adrenal veins are captured to provide detailed insights into their condition. The procedure concludes with the removal of the catheter, and the entire process is accompanied by radiological supervision, which includes the review and interpretation of the images obtained, culminating in a comprehensive written report of the findings.
