CPT® Code 75731

The procedure described by CPT® Code 75731 refers to a selective angiography of the adrenal gland performed unilaterally, which involves the use of radiopaque contrast medium and fluoroscopy to visualize the adrenal arteries. This imaging technique is crucial for assessing the vascular structure of the adrenal glands, which can be instrumental in diagnosing various adrenal conditions. The adrenal glands are small, triangular-shaped glands located on top of each kidney, and they play a significant role in hormone production. The procedure is particularly useful in identifying abnormalities such as adrenal hyperplasia, which is an enlargement of the adrenal glands; adrenal adenomas, which are benign tumors; pheochromocytomas, which are tumors that can affect hormone production; and metastatic lesions, which indicate the spread of cancer to the adrenal glands. During the procedure, a large bore needle is inserted into a blood vessel, typically in the groin area, allowing for the introduction of a guidewire. This guidewire facilitates the advancement of a catheter into the abdominal aorta under x-ray guidance. The adrenal arteries, which receive blood supply from branches of the abdominal aorta and renal artery, are selectively catheterized. Once the catheter is positioned correctly, a contrast dye is injected to enhance the visibility of the adrenal glands and surrounding tissues on the imaging studies. The procedure includes not only the angiographic imaging but also the radiological supervision and interpretation of the findings, culminating in a comprehensive written report that details the results of the examination.
