CPT® Code 74470

A radiologic examination known as a renal cyst study is performed using a translumbar approach, which involves accessing the renal cyst through the lower back. This procedure is conducted under fluoroscopic guidance, allowing for real-time imaging during the intervention. A needle is carefully inserted through the skin in the lumbar region and directed into the renal cyst. Once the needle is in place, a radiopaque contrast medium is injected into the cyst. This contrast agent enhances the visibility of the cyst on X-ray images, enabling the radiologist to obtain detailed images for analysis. The radiologist evaluates these images for specific characteristics that may suggest malignancy, such as the shape of the cyst, the margination of its walls, its enhancement properties, and any presence of septa or nodular protuberances. The CPT® Code 74470 is utilized to report the radiological supervision and interpretation of this procedure, which includes the administration of the contrast medium, the review of the obtained images, and the generation of a comprehensive written report detailing the findings of the study.
