Duplication of intestine

This code represents a congenital anomaly characterized by the presence of an extra segment of the gastrointestinal tract that is contiguous with or attached to the normal intestine. These duplications are typically cystic or tubular structures, share a common blood supply with the adjacent bowel, and are lined with gastrointestinal mucosa. They can occur anywhere from the esophagus to the rectum, with the ileum being the most common site.

Use this code when documentation confirms a congenital duplication of any part of the intestine. This diagnosis is often made prenatally via ultrasound or postnatally due to symptoms such as abdominal pain, vomiting, bleeding, or obstruction. Surgical resection is a common treatment, and this code would be used for the diagnosis leading to such intervention.

• Specify the exact location of the intestinal duplication if documented (e.g., ileal, jejunal) using additional codes if available for greater specificity.
• Do not confuse with other congenital malformations of the intestine, such as atresia or stenosis, which have distinct codes.
• Always review operative reports and pathology findings for definitive diagnosis and location.
