Intestinal Pseudo-Obstruction
Intestinal pseudo-obstruction is a motility disorder characterized by distention or dilatation of the small and/or large intestine. The underlying cause is not a mechanical obstruction of the intestine but rather a severe dysmotility of the intestine. Note: As of October 1, 1998, pseudo-obstruction of the intestine specified as chronic, intermittent secondary, idiopathic or primary, and not otherwise specified is coded to 564.89. Pseudo-obstruction of the intestine described as chronic or intermittent secondary, idiopathic or primary, and not otherwise specified (NOS) is assigned to code 564.8, Other specified functional disorders of intestine. Acute pseudo-obstruction of the intestine, also...

Article Overview
This article explains intestinal pseudo-obstruction in broad clinical and coding terms, with emphasis on how different presentations have been classified in ICD-9-CM and how related conditions may be coded alongside it. It is relevant to coders, auditors, and clinical documentation staff working with gastrointestinal motility disorders, bowel distention, and associated conditions. The article also discusses general treatment-related documentation topics that may affect code selection, without serving as a substitute for the full premium guidance.
Why This Topic Matters
Accurate documentation of intestinal pseudo-obstruction can affect whether the condition is classified as chronic, intermittent, idiopathic, secondary, or acute, and whether related diagnoses are also captured. The article helps users understand the scope of the topic and the coding framework associated with it.
