Intussusception

This code describes intussusception, a serious condition where one segment of the intestine telescopes into an immediately adjacent segment. This invagination can lead to intestinal obstruction, ischemia, and potentially necrosis if not promptly treated. It is most common in infants and young children but can occur at any age.

Apply this code when documentation clearly indicates a diagnosis of intussusception, regardless of the specific location (e.g., ileocolic, ileoileal). This code is supported by physician's notes detailing clinical presentation (e.g., abdominal pain, vomiting, "currant jelly" stools), imaging findings (e.g., ultrasound showing a "target sign"), or surgical findings confirming the telescoping of the bowel.

• Differentiate from other causes of intestinal obstruction; this code is specific to intussusception.
• If the intussusception is due to a pathological lead point (e.g., polyp, Meckel's diverticulum), code the underlying cause in addition to the intussusception.
• Consider additional codes for complications such as intestinal obstruction (e.g., 560.9) or peritonitis if documented.
