CPT® Code 74430

CPT® Code 74430 refers to a diagnostic imaging procedure known as cystography, which involves the use of fluoroscopy and a radiopaque contrast medium to examine the bladder. This procedure is essential for visualizing the bladder's structure and function, particularly in diagnosing various conditions. The term "radiological supervision" indicates that a qualified radiologist oversees the procedure, ensuring that it is performed correctly and safely. Cystography is particularly useful in identifying issues such as vesicoureteral reflux, which is the abnormal flow of urine from the bladder back into the ureters; bladder tumors, which are abnormal growths that can indicate cancer; polyps, which are growths that can develop on the bladder wall; and injuries to the bladder that may result from trauma or other medical conditions. Before the cystography begins, an X-ray of the bladder or urinary tract may be performed without contrast to provide a baseline image. During the procedure, a catheter is carefully inserted through the urethra into the bladder, allowing for the instillation of the contrast medium. This contrast is introduced until the bladder is adequately distended, enabling clear imaging. Multiple X-rays are then taken from various angles to capture detailed views of the bladder and ureters. After the imaging is completed, the catheter is removed, and the patient is allowed to void. An additional X-ray is taken post-voiding to confirm that all contrast material has been expelled from the bladder. The comprehensive nature of this procedure is encapsulated in CPT® Code 74430, which includes the radiological supervision, a minimum of three views, the review of records, interpretation of the findings, and the generation of a written report detailing the results of the cystography.
