What condition describes the telescoping of a portion of the intestine into another?

The condition that describes the telescoping of a portion of the intestine into another is intussusception. This occurs when a segment of the intestine folds into an adjacent segment, leading to obstruction of the bowel and potential complications such as reduced blood flow to the affected area. Symptoms can include abdominal pain, nausea, vomiting, and, in some cases, visible masses in the abdomen.

Understanding the specifics of this condition is crucial in the context of inpatient coding, as it is associated with significant clinical management. Intussusception typically requires prompt medical intervention, often involving imaging studies and possible surgical procedures to address the obstruction and prevent complications such as perforation or necrosis of the intestinal tissue.
