ICD-10 Code K91.32 – Postprocedural complete intestinal obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K91.32 – Postprocedural complete intestinal obstruction
What it is
K91.32 identifies a complete bowel obstruction that develops after a procedure. Use it when documentation shows the obstruction is a direct postprocedural complication, not a preexisting intestinal blockage.
Clinical signs
Typical findings include absent stool or flatus, abdominal distension, vomiting, and imaging evidence of a complete obstruction. Clinical features vary; refer to documentation.
When to use this code
Use K91.32 when the provider documents complete intestinal obstruction due to a recent surgery or other procedure. It is appropriate when the note clearly links the obstruction to the procedure and excludes other causes. Check documentation if the record does not state the relationship.
Do not use for
Do not use this code for partial obstruction, ileus, or intestinal obstruction present before the procedure. If the cause is uncertain or unrelated, select the documented condition instead.
Coding tip
Confirm the postprocedural relationship in the operative or progress note before assigning K91.32.
