Congen absence, atresia and stenosis of lg int, part unsp

This code signifies a birth defect characterized by the complete absence, abnormal narrowing, or complete blockage of the large intestine, where the specific affected segment is not documented. This congenital anomaly prevents normal passage of stool and often presents with symptoms of intestinal obstruction in neonates.

Use this code when documentation clearly indicates a congenital malformation of the large intestine involving absence, atresia, or stenosis, but the specific part (e.g., cecum, colon, rectum) is not specified. This code is appropriate for initial diagnoses in newborns presenting with signs of large bowel obstruction due to an unlocalized congenital defect.

• Always seek clarification from the provider if the specific segment of the large intestine affected by absence, atresia, or stenosis is not documented.
• Avoid using this code if a more specific code (e.g., Q42.0-Q42.8) can be assigned based on documentation.
• Sequence this code as the primary diagnosis when it is the reason for the encounter and treatment.
