ICD-10 Code K94.09 – Other complications of colostomy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K94.09 – Other complications of colostomy
What it is
K94.09 identifies complications involving a colostomy that are not classified elsewhere. Use it for documented stoma-related problems when the record does not name a more specific complication code.
Clinical signs
Clinical features vary; refer to documentation. Notes may describe stoma dysfunction, leakage, irritation, obstruction, prolapse, or other colostomy-related problems requiring assessment.
When to use this code
Use K94.09 when the provider documents an unspecified or other complication of a colostomy and no more specific code applies. It fits postoperative or follow-up encounters where the complication is clearly linked to the colostomy. Check documentation if the chart only mentions ostomy care without a complication.
Do not use for
Do not use this code for routine colostomy status, appliance care, or general stoma education without a complication. If the record identifies a different stoma type or a more specific complication, code that instead.
Coding tip
Code the complication only when the provider links it directly to the colostomy and documents the specific problem, even if the exact mechanism is not stated.
