Fistula of vagina to small intestine

This code signifies an abnormal connection or passageway that has formed between the vagina and the small intestine. This type of fistula allows intestinal contents to bypass the normal digestive and excretory pathways, leading to symptoms such as fecal discharge from the vagina.

Apply this code when documentation clearly indicates a direct communication between the vaginal canal and any part of the small intestine (duodenum, jejunum, or ileum). This often arises as a complication of surgery, inflammatory bowel disease, radiation therapy, or trauma.

• Ensure documentation specifies "small intestine" and not colon or rectum, which would necessitate a different code.
• Distinguish from rectovaginal or colovaginal fistulas; this code is specific to the small bowel.
• Code any underlying cause (e.g., Crohn's disease, surgical complication) as an additional diagnosis.
