Volvulus

This code represents a condition where a loop of the intestine twists around itself and the mesentery that supports it, leading to bowel obstruction. This twisting can cut off the blood supply to the affected segment, potentially causing ischemia and necrosis if not promptly treated.

Use this code for documented cases of intestinal volvulus affecting any part of the bowel except the duodenum. Clinical scenarios include acute abdominal pain, distension, vomiting, and obstipation, with imaging studies confirming the characteristic "whirl sign" or other signs of bowel twisting.

• Ensure documentation specifies the location of the volvulus to rule out duodenal involvement.
• Always code any associated bowel obstruction or gangrene separately, as these are complications.
• Review operative reports for definitive diagnosis and extent of the volvulus.
