2026 ICD-10-CM Diagnosis Code K50.01 – Crohn’s disease of small intestine with complications
What it is
K50.01 identifies Crohn’s disease affecting the small intestine when complications are documented. It signals inflammatory bowel disease with a complicated course, such as obstruction, fistula, abscess, or other specified complication.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include abdominal pain, diarrhea, weight loss, and evidence of small-bowel inflammation with a recorded complication such as stricture, perforation, or fistula.
When to use this code
Use K50.01 when the provider documents Crohn’s disease of the small intestine and clearly states a complication. This code fits encounters for confirmed complicated disease, including imaging, endoscopy, or operative notes that specify the complication. Check documentation if the site or complication is unclear.
Do not use for
Do not use this code for Crohn’s disease without a documented complication, or when the disease is limited to another GI site. If the complication is not specified, check documentation.
Coding tip
Code the complication only when it is explicitly documented and supported by the record; otherwise, query for clarification.
