Congenital occlusion of ureter, unspecified

This code signifies a birth defect where a ureter is completely blocked, preventing urine flow from the kidney to the bladder. The specific location or cause of the obstruction within the ureter is not documented or is unknown. This congenital anomaly can lead to hydronephrosis and potential kidney damage if not addressed.

Apply this code when documentation indicates a congenital complete blockage of the ureter, but the precise segment of the ureter involved (e.g., proximal, mid, distal) is not specified. This is often used in initial diagnostic workups or when imaging reports describe a complete ureteral obstruction of congenital origin without further anatomical detail.

• Do not use if the specific location of the congenital ureteral occlusion is documented (e.g., at the ureteropelvic junction, ureterovesical junction).
• Always sequence this code before any codes for associated complications, such as hydronephrosis (N13.0-N13.8).
• Query the provider for more specific anatomical detail if available to allow for a more precise code selection.
