Obstruction of duodenum

This code signifies a blockage within the duodenum, the first section of the small intestine, that is not present at birth. This obstruction can impede the passage of food and digestive fluids, leading to symptoms such as nausea, vomiting, abdominal pain, and distension.

Assign this code for acquired duodenal obstructions identified through imaging studies (e.g., X-ray, CT scan, endoscopy) or surgical exploration. Documentation should clearly state an obstruction of the duodenum and rule out a congenital etiology. This code is appropriate for conditions like strictures, tumors, or external compression causing the blockage.

• Ensure documentation explicitly states "acquired" or "non-congenital" to differentiate from Q41.0.
• Investigate the underlying cause of the obstruction (e.g., tumor, stricture) and code it as a primary or secondary diagnosis as appropriate.
• Do not use this code if the obstruction is identified as congenital, as Q41.0 would be the correct code.
