ICD-10 Code K50.111 – Crohn’s disease of large intestine with rectal bleeding (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K50.111 – Crohn’s disease of large intestine with rectal bleeding
What it is
K50.111 identifies Crohn’s disease affecting the large intestine when rectal bleeding is documented. Use it for inflammatory bowel disease involving the colon with bleeding from the rectum.
Clinical signs
Typical findings include chronic bowel inflammation with colonic involvement and documented rectal bleeding. Clinical features vary; refer to documentation for the specific site and whether bleeding is attributed to Crohn’s disease.
When to use this code
Use this code when the provider documents Crohn’s disease of the large intestine and also notes rectal bleeding. It fits encounters where the bleeding is part of the Crohn’s presentation, not a separate anorectal problem. Check documentation if the record only says lower gastrointestinal bleeding.
Do not use for
Do not use it when Crohn’s disease is limited to another intestinal site, or when rectal bleeding is documented without Crohn’s disease. If the chart does not specify colonic involvement, check documentation.
Coding tip
Code the Crohn’s site and the bleeding detail together; if either is unclear, query the provider.
