ICD-10 Code K50 – Crohn’s disease [regional enteritis] (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K50 – Crohn’s disease [regional enteritis]
What it is
K50 identifies Crohn’s disease, a chronic inflammatory bowel disease that can affect any part of the gastrointestinal tract. Use it when documentation states Crohn’s disease or regional enteritis.
Clinical signs
Clinical features vary; refer to documentation. Common findings include abdominal pain, diarrhea, weight loss, and evidence of intestinal inflammation or complications such as strictures or fistulas.
When to use this code
Use K50 when the provider documents Crohn’s disease without a more specific site or complication code. It also fits records describing regional enteritis, Crohn’s colitis, or Crohn’s ileitis when the chart supports that diagnosis. Check documentation for any specified site or complication that may require a more detailed code.
Do not use for
Do not use K50 for ulcerative colitis, infectious enteritis, or nonspecific abdominal pain. If the note only says “possible Crohn’s” or “rule out Crohn’s,” check documentation.
Coding tip
Review the full record for site and complication details, because a more specific K50 code may be available.
