CPT® Code 74485

The CPT® Code 74485 refers to the procedure of dilation of the ureter(s) or urethra, which is performed under radiological supervision and interpretation. This procedure is essential in addressing conditions such as stenosis or obstruction within the ureter or urethra, which can lead to significant complications if left untreated. Stenosis refers to the narrowing of these tubular structures, while obstruction indicates a blockage that can impede the normal flow of urine. The procedure involves the use of imaging techniques to guide the dilation process, ensuring precision and safety. During the dilation, a cystourethroscope is utilized to navigate through the urethra and bladder into the ureter, allowing for the insertion of a guidewire. This guidewire serves as a pathway for a ureteroscope, which is then used to reach the area of the stricture. The introduction of contrast medium and subsequent X-ray imaging are critical steps that facilitate the visualization of the ureter or urethra, enabling the healthcare provider to assess the extent of the obstruction or narrowing accurately. The dilation itself may be performed using a balloon dilator or progressively larger dilators, depending on the specific requirements of the case. The comprehensive nature of this procedure, including the radiological supervision, interpretation of findings, and documentation in a written report, underscores its complexity and the necessity for skilled professionals to execute it effectively.
