ICD-10 Code K50.118 – Crohn’s disease of large intestine with other complication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K50.118 – Crohn’s disease of large intestine with other complication
What it is
K50.118 identifies Crohn’s disease limited to the large intestine, with an additional documented complication. Use it when the record clearly states colonic Crohn’s disease and a complication that is not separately coded elsewhere.
Clinical signs
Clinical features vary; refer to documentation. Common findings in Crohn’s disease include chronic abdominal pain, diarrhea, weight loss, and evidence of inflammatory bowel disease affecting the colon.
When to use this code
Use this code when the provider documents Crohn’s disease of the large intestine and specifies another complication, such as a complication related to the disease process. Verify that the complication is part of the current encounter and not a separate, unrelated condition. If the record does not clearly identify the complication, check documentation.
Do not use for
Do not use it for Crohn’s disease of the small intestine, small and large intestine, or unspecified site. Do not assign it when no qualifying complication is documented.
Coding tip
Confirm both the anatomic site and the complication in the provider note before coding K50.118.
