ICD-10 Code K50.112 – Crohn’s disease of large intestine with intestinal obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K50.112 – Crohn’s disease of large intestine with intestinal obstruction
What it is
K50.112 identifies Crohn’s disease limited to the large intestine when the chart also documents intestinal obstruction. Use it when the record supports both the Crohn’s location and the obstructive complication.
Clinical signs
Patients may have abdominal pain, cramping, diarrhea, and signs of bowel narrowing or blockage. Clinical features vary; refer to documentation for the specific evidence of large-intestine involvement and obstruction.
When to use this code
Use this code when the provider documents Crohn’s disease of the colon with obstruction, including partial or complete intestinal obstruction. It is appropriate when the obstruction is attributed to the Crohn’s process and the site is clearly the large intestine.
If the note only says Crohn’s disease without location or obstruction, you should not assume K50.112. Check documentation for the exact bowel segment and whether obstruction is present.
Do not use for
Do not use this code for Crohn’s disease without obstruction or for disease limited to the small intestine. Do not apply it when the obstruction has a different documented cause.
Coding tip
Verify both elements in the record: large-intestine Crohn’s disease and intestinal obstruction, before assigning K50.112.
