ICD-10 Code K94.01 – Colostomy hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K94.01 – Colostomy hemorrhage
What it is
K94.01 identifies bleeding from a colostomy site or stoma. Use it when the record states colostomy hemorrhage, stoma bleeding, or similar wording.
Clinical signs
Typical findings include visible blood at or around the colostomy, blood in the ostomy pouch, or documentation of active stoma bleeding. Clinical features vary; refer to documentation.
When to use this code
Use K94.01 when the provider documents hemorrhage specifically involving a colostomy. It fits encounters for evaluation of bleeding from the stoma or peristomal area when the colostomy is the source. Check documentation if the note only says gastrointestinal bleeding or postoperative complication without naming the colostomy.
Do not use for
Do not use this code for bleeding from another ostomy type, such as an ileostomy, or for unrelated lower gastrointestinal bleeding. If the source is unclear, check documentation.
Coding tip
Code the bleeding source exactly as documented; if the note says colostomy hemorrhage, K94.01 is the specific choice.
