CPT® Code 74425

Add-On Code

Urography, antegrade, is a radiological procedure designed to visualize the anatomy and function of the kidneys and ureters. This procedure is essential for assessing urinary drainage and diagnosing various conditions affecting the urinary tract. It involves the injection of a radiopaque contrast medium, which enhances the visibility of these structures during imaging. The contrast can be administered through a percutaneously placed needle or tube, or via an indwelling catheter, allowing for a detailed examination of the renal pelvis, ureters, and the flow of urine. Antegrade urography encompasses several specific procedures, including pyelostogram, nephrostogram, and ureteropyelogram, which are utilized to identify abnormalities such as strictures, stones, and tumors. Additionally, this technique is valuable for evaluating the status of previously placed nephrostomy, pyelostomy, or ureterostomy catheters, as well as for visualizing implanted ureters in patients with an ileal conduit. The procedure typically begins with the administration of a local anesthetic to minimize discomfort, followed by the insertion of a needle guided by fluoroscopy to the target site, where the contrast medium is injected. This results in the capture of radiologic images that provide critical information regarding the upper urinary tract and its function. It is important to note that CPT® Code 74425 specifically refers to the radiological supervision and interpretation of the antegrade urography procedure, which includes the analysis of the obtained images and the generation of a comprehensive written report detailing the findings.
