CPT® Code 74420

The procedure described by CPT® Code 74420 refers to retrograde urography, a diagnostic imaging technique used to visualize the kidneys and ureters. In this procedure, a contrast dye, often referred to as a special dye, is introduced directly into the renal pelvis and ureters. This is done against the natural flow of urine, allowing for enhanced visibility of these structures during imaging. The primary goal of retrograde urography is to obtain detailed X-ray images that can help identify abnormalities or blockages within the urinary tract. The procedure may also include a general X-ray of the abdomen to provide additional context and information about the surrounding anatomical structures. This imaging technique is particularly useful in assessing conditions such as kidney stones, tumors, or other obstructions that may affect urinary function.
