Atresia and stenosis of small intestine

This code signifies a congenital malformation of the small intestine characterized by either a complete obstruction (atresia) or a significant narrowing (stenosis) of the lumen. These conditions impede the normal passage of intestinal contents, often leading to neonatal bowel obstruction.

Apply this code for documented cases of congenital small intestinal atresia or stenosis identified at birth or shortly thereafter. Supporting documentation typically includes imaging studies (e.g., abdominal X-rays, contrast studies) demonstrating the obstruction, surgical findings, and pathology reports confirming the malformation.

• Differentiate between congenital and acquired strictures; this code is specifically for congenital forms.
• Specify the exact location within the small intestine (e.g., duodenal, jejunal, ileal) if documented, as this may impact surgical approach and prognosis.
• Consider additional codes for associated congenital anomalies or complications, such as malrotation or perforation.
