ICD-10 Code K56.7 – Ileus, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K56.7 – Ileus, unspecified
What it is
K56.7 identifies an ileus without a more specific type documented. It means the bowel is not moving contents normally, but the record does not specify the cause or location.
Clinical signs
Typical findings include abdominal distension, nausea, vomiting, decreased or absent bowel sounds, and reduced passage of stool or flatus. Clinical features vary; refer to documentation.
When to use this code
Use K56.7 when the provider documents ileus but does not specify paralytic, postoperative, or another defined form. It also fits cases where the note confirms bowel hypomotility without further detail. If the record names a more specific ileus, code that instead.
Do not use for
Do not use this code for mechanical intestinal obstruction, constipation, or a clearly documented postoperative ileus if a more specific code is available. Check documentation.
Coding tip
Review the operative note and assessment carefully; if the type of ileus is stated, choose the more specific code.
