Supravesical fissure of urinary bladder

This code describes a congenital anomaly where there is an incomplete closure of the anterior abdominal wall and bladder, resulting in a persistent opening (fissure) above the bladder. This defect allows urine to leak from the bladder to the outside of the body. It is a more severe form of bladder exstrophy, often associated with other genitourinary malformations.

Use this code for patients diagnosed with a supravesical fissure of the urinary bladder, which is a congenital defect. Documentation should clearly indicate the presence of an opening superior to the bladder, often with associated urine leakage. This diagnosis is typically made at birth or shortly thereafter.

• Ensure documentation specifies "supravesical" to differentiate from other types of bladder exstrophy or fistulas.
• Code any associated congenital anomalies of the genitourinary system or other body systems separately.
• This code is for the congenital defect itself, not for complications or surgical repair procedures, which would be coded additionally.
