Vesical fistula, not elsewhere classified

This code represents an abnormal passage or tract connecting the urinary bladder to another organ or the skin, which is not congenital or due to diverticula. It signifies an acquired communication that allows urine to leak from the bladder.

Use this code for documented cases of acquired vesical fistulas, such as a vesicovaginal fistula following hysterectomy, a vesicocutaneous fistula post-surgical complication, or a vesicoenteric fistula from inflammatory bowel disease. Documentation should clearly specify the bladder as one component of the fistula and rule out congenital origins.

• Always identify the communicating organ(s) to ensure appropriate secondary coding for the specific type of fistula (e.g., vesicovaginal, vesicoenteric).
• Distinguish from congenital fistulas, which are coded differently.
• Consider an external cause code if the fistula is iatrogenic or due to trauma.
