Congenital absence, atresia and stenosis of prt lg int

Congenital absence, atresia and stenosis of other parts of large intestine

📋Clinical Description

This code signifies a birth defect affecting the large intestine, specifically the congenital absence (agenesis), complete blockage (atresia), or narrowing (stenosis) of parts other than the anus or rectum. These anomalies disrupt normal bowel function and often require surgical intervention.

🎯When to Use

Use this code for documented cases of congenital malformations such as colonic atresia, segmental absence of the colon, or congenital strictures of the large intestine. Documentation should clearly specify the congenital nature and the affected part of the large intestine, excluding the anus and rectum.

💡Coding Tips

Differentiate from acquired strictures or obstructions of the large intestine, which are coded differently.
Ensure documentation specifies "congenital" to support the use of this Q-code.
Consider sequencing this code as the primary diagnosis when it is the reason for the encounter, followed by any associated symptoms or complications.
