Congenital posterior urethral valves

This code represents a congenital anomaly characterized by obstructive folds of tissue located in the posterior urethra of male infants. These valves impede the flow of urine from the bladder, leading to urinary tract obstruction and potential damage to the kidneys and bladder.

Assign this code for documented cases of posterior urethral valves identified prenatally, at birth, or during infancy. Supporting documentation includes imaging studies (e.g., voiding cystourethrogram), cystoscopy findings, or surgical reports confirming the presence of these obstructive valves.

• Always specify any associated conditions, such as hydronephrosis or renal dysplasia, with additional codes.
• Do not confuse with acquired urethral strictures or other forms of congenital urethral obstruction.
• Ensure the documentation clearly indicates "posterior" urethral valves to differentiate from other urethral anomalies.
