Clinical Classification

Clinical Information

  • Short Bowel Syndrome

    a malabsorption syndrome resulting from extensive operative resection of the small intestine, the absorptive region of the gastrointestinal tract.
  • 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.
  • Blind Loop Syndrome

    a malabsorption syndrome that is associated with a blind loop in the upper small intestine that is characterized by the lack of peristaltic movement, stasis of intestinal contents, and the overgrowth of bacteria. such bacterial overgrowth interferes with bile salts action, fatty acids processing, microvilli integrity, and the absorption of nutrients such as vitamin b12 and folic acid.
  • Intestinal Volvulus

    a twisting in the intestine (intestines) that can cause intestinal obstruction.
  • Tortuous Colon

    a colon that is longer than a normal colon, with additional bends and twists.
  • Congenital Diaphragmatic Hernia

    diaphragmatic hernia that is present at birth.
  • Microcolon

    a rare congenital abnormality characterized by the presence of an abnormally small colon. it is the result of intestinal underutilization during fetal development.
  • MMIH Syndrome|Megacystis, Microcolon, Hypoperistalsis Syndrome|Megacystis, Microcolon, Intestinal Hypoperistalsis Syndrome|Megacystis, Microcolon, Intestinal Hypoperistalsis Syndrome

    a rare syndrome characterized by the presence of an enlarged and weak bladder (megacystis), a very small large intestine (microcolon), and weak small intestine that does not function properly (hypoperistalsis). it is caused by a disorder of the smooth muscles of the abdomen and gastrointestinal tract.
  • Low Anorectal Malformation

    congenital malformations in the anorectal region that include the perineal fistula, anteriorly placed anus, and anorecto-vestibular fistula.
  • Short Bowel Syndrome

    malabsorption that results from the removal of a large segment of the small intestine or, less frequently, from the complete dysfunction of a large portion of the small intestine. signs and symptoms include diarrhea, steatorrhea, and weight loss.
  • Duodenal Web

    partial or complete obstruction of the duodenal lumen due to the presence of a membranous web.
  • Rectal Prolapse

    protrusion of the rectum through the anus.
  • Intestinal Volvulus

    twisting of a loop of bowel that results in intestinal obstruction.

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.

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Present on Admission (POA)

Q43.8 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

CMS POA Indicator Options and Definitions

POA IndicatorReason for CodeCMS will pay the CC/MCC DRG?

Convert Q43.8 to ICD-9-CM

    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education

Colonic Diseases

Your colon, also known as the large intestine, is part of your digestive system. It's a long, hollow tube at the end of your digestive tract where your body makes and stores stool. Many disorders affect the colon's ability to work properly. Some of these include:

  • Colorectal cancer
  • Colonic polyps - extra tissue growing in the colon that can become cancerous
  • Ulcerative colitis - ulcers of the colon and rectum
  • Diverticulitis - inflammation or infection of pouches in the colon
  • Irritable bowel syndrome - an uncomfortable condition causing abdominal cramping and other symptoms

Treatment for colonic diseases varies greatly depending on the disease and its severity. Treatment may involve diet, medicines and in some cases, surgery.

Small Intestine Disorders

Your small intestine is the longest part of your digestive system - about twenty feet long! It connects your stomach to your large intestine (or colon) and folds many times to fit inside your abdomen. Your small intestine does most of the digesting of the foods you eat. It has three areas called the duodenum, the ileum, and the jejunum.

Problems with the small intestine can include:

  • Bleeding
  • Celiac disease
  • Crohn's disease
  • Infections
  • Intestinal cancer
  • Intestinal obstruction
  • Irritable bowel syndrome
  • Ulcers, such as peptic ulcer

Treatment of disorders of the small intestine depends on the cause.
