ICD-10 Code K50.011 – Crohn’s disease of small intestine with rectal bleeding (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K50.011 – Crohn’s disease of small intestine with rectal bleeding
What it is
K50.011 identifies Crohn’s disease affecting the small intestine when rectal bleeding is documented. Use it for inflammatory bowel disease with this specific anatomic site and bleeding manifestation.
Clinical signs
Clinical features vary; refer to documentation. Typical Crohn’s disease findings may include abdominal pain, diarrhea, weight loss, and evidence of intestinal inflammation, with rectal bleeding specifically noted in the record.
When to use this code
Use this code when the provider documents Crohn’s disease of the small intestine and also records rectal bleeding. It fits encounters where both the disease location and bleeding are clearly linked in the assessment. Check documentation if the bleeding source is uncertain or if the disease site is not specified.
Do not use for
Do not use this code for Crohn’s disease without rectal bleeding, or when bleeding comes from another documented cause. If the condition involves a different intestinal site, choose the code that matches the documented location.
Coding tip
Code only when the small-intestine site and rectal bleeding are both explicitly documented.
