ICD-10 Code K50.11 – Crohn’s Disease of Large Intestine with Complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K50.11 – Crohn’s disease of large intestine with complications
What it is
K50.11 identifies Crohn’s disease affecting the large intestine when the record also documents complications. Use this code when the colonic Crohn’s diagnosis is clearly stated and a complication is linked to it.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include chronic abdominal pain, diarrhea, rectal bleeding, weight loss, or evidence of inflammatory complications involving the colon.
When to use this code
Use K50.11 when the provider documents Crohn’s disease of the large intestine and specifies a complication, such as obstruction, fistula, abscess, or other related complication. Make sure the complication is part of the current assessment, not just a past history item.
If the note identifies Crohn’s disease but does not clearly state the site or complication, check documentation before coding. You may need a more specific Crohn’s code if the record supports a different intestinal location.
Do not use for
Do not use this code for Crohn’s disease without a documented complication, or when the disease site is not the large intestine. Check documentation if the complication is unrelated or not attributed to Crohn’s disease.
Coding tip
Code the site and complication exactly as documented, and query the provider if either element is unclear.
