ICD10 code of Chronic Intestinal Pseudo-Obstruction and ICD9 code

Chronic Intestinal Pseudo-Obstruction (CIPO) is primarily classified under ICD-10 code K55.21 (Chronic intestinal pseudo-obstruction) and was historically categorized under ICD-9 code 560.89 (Other specified intestinal obstruction). These codes are essential for medical billing, insurance authorization, and clinical documentation for patients managing this complex motility disorder.

What is Chronic Intestinal Pseudo-Obstruction?

Chronic Intestinal Pseudo-Obstruction is a rare, severe motility disorder where the muscles and nerves of the gastrointestinal tract fail to coordinate, mimicking a mechanical blockage despite no physical obstruction being present. Because Chronic Intestinal Pseudo-Obstruction can involve the esophagus, stomach, small intestine, or colon, accurate coding is vital for coordinating multidisciplinary care.

How are ICD codes used for Chronic Intestinal Pseudo-Obstruction?

Medical providers use these specific codes to communicate the severity and nature of Chronic Intestinal Pseudo-Obstruction to insurers and specialists. Proper documentation ensures that patients receive coverage for necessary diagnostic testing and long-term management strategies, such as nutritional support or motility agents.

What are the key clinical identifiers for coding?

When documenting Chronic Intestinal Pseudo-Obstruction, clinicians often rely on specific diagnostic criteria to support the ICD-10 classification:

• Evidence of ineffective peristalsis (manometry or transit studies).


• Recurrent episodes of abdominal distension, pain, and vomiting.


• Exclusion of mechanical obstruction via imaging (CT/MRI/Enteroscopy).


• Nutritional compromise (malnutrition or dependence on parenteral nutrition).
