ICD-10 Code K94.00 – Colostomy complication, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K94.00 – Colostomy complication, unspecified
What it is
K94.00 identifies a complication involving a colostomy when the documentation does not specify the exact problem. Use it for stomal or peristomal issues tied to the colostomy, but not for routine ostomy care.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings may include leakage, irritation, bleeding, pain, swelling, or difficulty maintaining the appliance seal around the colostomy.
When to use this code
Use this code when the provider documents a colostomy complication but does not name the specific type. It is appropriate for unspecified stomal problems, peristomal skin issues, or appliance-related complications linked to the colostomy. If the record gives a clearer diagnosis, code that instead.
Do not use for
Do not use K94.00 for a normal, functioning colostomy without complications. Do not use it when the documentation identifies a more specific ostomy complication or a non-colostomy gastrointestinal condition.
Coding tip
Query for the exact complication whenever the note only says “colostomy problem” or “ostomy issue.”
