ICD-10 Code K50.00 – Crohn’s disease of small intestine without complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K50.00 – Crohn’s disease of small intestine without complications
What it is
K50.00 identifies Crohn’s disease limited to the small intestine, with no documented complications. It is used when the record supports Crohn’s disease but does not describe abscess, fistula, obstruction, or other complications.
Clinical signs
Typical findings include chronic abdominal pain, diarrhea, weight loss, and evidence of small-bowel inflammation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents Crohn’s disease of the small intestine and specifically states there are no complications. It also fits when imaging, endoscopy, or pathology supports small-bowel Crohn’s disease without mention of penetrating, obstructive, or perianal disease. If the record is unclear, check documentation.
Do not use for
Do not use K50.00 if the chart documents complications such as fistula, abscess, obstruction, or bleeding. Also avoid it when Crohn’s disease involves other intestinal sites or the documentation does not specify the small intestine.
Coding tip
Code the site and complication status exactly as documented; if either is missing, query or check documentation before assigning K50.00.
