Other congenital malformations of intestine (Q43)

The ICD-10 code Q43 covers various congenital malformations of the intestine, including specific anomalies like Meckel's diverticulum (Q43.0), Hirschsprung's disease (Q43.1), and other structural or functional intestinal disorders present from birth.

These codes are used to classify unique conditions involving abnormal development of the intestine that infants are born with. For example, Q43.0 includes displaced or hypertrophic Meckel's diverticulum, also known as intra-abdominal vitelline remnants or bleeding Meckel's diverticulitis. Q43.1 identifies Hirschsprung's disease, which is also called congenital aganglionic megacolon or primary megacolon, characterized by missing nerve cells in parts of the colon. Other codes like Q43.3 address congenital malformations of intestinal fixation such as malrotation or volvulus, while Q43.4 covers duplications of the intestines. Less common anomalies like ectopic anus (Q43.5) and persistent cloaca (Q43.7) are also included. This ICD-10 code range allows precise documentation for a wide spectrum of congenital intestinal malformations, aiding accurate diagnosis and treatment planning.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

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.

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.

Short Bowel Syndrome

A malabsorption syndrome resulting from extensive operative resection of the SMALL INTESTINE, the absorptive region of the GASTROINTESTINAL TRACT.

Waardenburg Syndrome

Rare, autosomal dominant disease with variable penetrance and several known clinical types. Characteristics may include depigmentation of the hair and skin, congenital deafness, heterochromia iridis, medial eyebrow hyperplasia, hypertrophy of the nasal root, and especially dystopia canthorum. The underlying cause may be defective development of the neural crest (neurocristopathy). Waardenburg's syndrome may be closely related to piebaldism. Klein-Waardenburg Syndrome refers to a disorder that also includes upper limb abnormalities.
