Exstrophy of urinary bladder

This code represents a congenital anomaly characterized by the absence of the anterior bladder wall and the corresponding abdominal wall, resulting in the bladder being open and exposed to the outside. It is a severe birth defect where the bladder is turned inside out, and urine drains directly from the exposed bladder surface.

Use this code for documented cases of congenital exstrophy of the urinary bladder. This diagnosis is typically made at birth or shortly thereafter based on physical examination. Documentation should clearly describe the exposed bladder and associated abdominal wall defect.

• Ensure documentation specifies "urinary bladder" exstrophy to differentiate from cloacal exstrophy.
• Consider additional codes for associated congenital anomalies, which are common with exstrophy.
• This code is for the congenital condition itself, not for complications or surgical repairs.
