ICD-10 Code K56.609 – Unspecified intestinal obstruction, unspecified as to partial versus complete obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K56.609 – Unspecified intestinal obstruction, unspecified as to partial versus complete obstruction
What it is
K56.609 identifies an intestinal obstruction when the blocked bowel segment is not further specified and the record does not state whether it is partial or complete. Use it when documentation confirms obstruction but leaves the details unclear.
Clinical signs
Typical findings include abdominal pain, distention, nausea, vomiting, and reduced passage of stool or gas. Clinical features vary; refer to documentation for the exact site, cause, and severity.
When to use this code
Use this code when the provider documents intestinal obstruction but does not identify whether it is partial or complete. It also fits when the note does not specify the bowel segment or underlying cause. Check documentation before coding a more specific obstruction code.
Do not use for
Do not use this code if the record clearly states partial, complete, or another specific type of bowel obstruction. Do not use it for ileus or postoperative paralytic ileus unless the documentation supports intestinal obstruction.
Coding tip
If the chart is vague, query for the obstruction type, location, and cause before defaulting to K56.609.
