ICD-10 Code K94.02 – Colostomy infection (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K94.02 – Colostomy infection
What it is
K94.02 identifies an infection involving a colostomy site or the tissue around the stoma. Use it when documentation states the colostomy itself is infected, not just irritated or leaking.
Clinical signs
Typical findings include redness, swelling, warmth, pain, drainage, or foul odor around the stoma. Clinical features vary; refer to documentation for confirmation of infection.
When to use this code
Use this code when the provider documents a colostomy infection, stoma infection, or infected colostomy wound. It may also fit when the note clearly links peristomal infection to the colostomy. Check documentation if the record only mentions skin irritation, breakdown, or appliance leakage.
Do not use for
Do not use K94.02 for uncomplicated colostomy care, mechanical problems, or noninfectious skin irritation around the stoma. If the infection is documented elsewhere or is unclear, check documentation.
Coding tip
Code K94.02 only when infection is explicitly documented; do not infer infection from drainage or redness alone.
