CPT® Code 74410

The procedure described by CPT® Code 74410 involves urography, which is a diagnostic imaging technique used to visualize the urinary tract, including the kidneys, ureters, bladder, and urethra. This is achieved through the infusion of a contrast agent into a vein, which enhances the visibility of these structures on imaging studies. The primary purpose of this procedure is to assess the normal functioning of the urinary system, identify any anatomical variations or congenital anomalies, and detect potential obstructions or tumors within the urinary tract. The process begins with the establishment of intravenous access, followed by the acquisition of scout films of the kidneys, ureters, and bladder (KUB) to provide baseline images. The contrast material can be administered using either a bolus technique, which delivers a rapid infusion for immediate opacification, or a drip technique, which allows for a slower, more gradual infusion over an extended period. The choice of technique impacts the imaging process; a bolus infusion results in greater renal opacification but requires more fluoroscopic images, thereby increasing radiation exposure to the patient. Conversely, a drip infusion minimizes radiation exposure by requiring fewer images due to the prolonged delivery of contrast. Additionally, nephrotomography may be performed during this procedure, which involves imaging the urinary system in sections to create a three-dimensional representation. After the contrast has passed through the kidneys and ureters into the bladder, the patient is asked to void, and further imaging may be conducted to evaluate the function of the urethra. Post-void films are often obtained to confirm that the bladder has been completely emptied. Overall, CPT® Code 74410 encompasses the comprehensive urography procedure utilizing either the drip or bolus infusion technique for contrast administration.
