Clinical Information

  • Intussusception-. a form of intestinal obstruction caused by the prolapse of a part of the intestine into the adjoining intestinal lumen. there are four types: colic, involving segments of the large intestine; enteric, involving only the small intestine; ileocecal, in which the ileocecal valve prolapses into the cecum, drawing the ileum along with it; and ileocolic, in which the ileum prolapses through the ileocecal valve into the colon.
  • Rectal Prolapse-. protrusion of the rectal mucous membrane through the anus. there are various degrees: incomplete with no displacement of the anal sphincter muscle; complete with displacement of the anal sphincter muscle; complete with no displacement of the anal sphincter muscle but with herniation of the bowel; and internal complete with rectosigmoid or upper rectum intussusception into the lower rectum.
  • Rectal Prolapse-. protrusion of the rectum through the anus.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Intussusception or invagination of bowel
  • Intussusception or invagination of colon
  • Intussusception or invagination of intestine
  • Intussusception or invagination of rectum

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
  • intussusception of appendix K38.8

Intestinal Obstruction

An intestinal obstruction occurs when food or stool cannot move through the intestines. The obstruction can be complete or partial. There are many causes. The most common are adhesions, hernias, cancers, and certain medicines.

Symptoms include:

  • Severe abdominal pain or cramping
  • Vomiting
  • Bloating
  • Loud bowel sounds
  • Swelling of the abdomen
  • Inability to pass gas
  • Constipation

A complete intestinal obstruction is a medical emergency. It often requires surgery.
