ICD-10 Code K50.119 – Crohn’s Disease of Large Intestine with Unspecified Complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K50.119 – Crohn’s disease of large intestine with unspecified complications
What it is
K50.119 identifies Crohn’s disease affecting the large intestine when the record does not specify the complication. Use it for inflammatory bowel disease limited to the colon, with an unspecified associated complication.
Clinical signs
Typical findings include chronic abdominal pain, diarrhea, rectal bleeding, weight loss, and signs of colonic inflammation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents Crohn’s disease of the large intestine and notes a complication, but the complication is not named. It also fits when the chart confirms colonic Crohn’s disease with an unspecified complication. Do not assume a more specific complication from symptoms alone.
Do not use for
Do not use this code for Crohn’s disease limited to the small intestine, other digestive sites, or Crohn’s disease without complication. If the documentation names a specific complication, code that condition instead.
Coding tip
Query the provider when the chart says “complicated Crohn’s” but does not identify the complication.
