ICD-10 Code K50.80 – Crohn’s disease of both small and large intestine without complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K50.80 – Crohn’s disease of both small and large intestine without complications
What it is
K50.80 identifies Crohn’s disease involving both the small and large intestine, without documented complications. Use it when the record confirms this distribution and does not describe abscess, fistula, obstruction, or other complication.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include chronic abdominal pain, diarrhea, weight loss, and signs of inflammatory bowel disease affecting both bowel segments.
When to use this code
Use K50.80 when the provider documents Crohn’s disease in both the small and large intestine and specifically states there are no complications. It also fits when the note clearly supports this location pattern, even if symptoms are not detailed. Check documentation if the site or complication status is unclear.
Do not use for
Do not use this code if Crohn’s disease is limited to the small intestine, large intestine, or another site only. Also avoid it when a complication is documented; code the more specific complicated category instead.
Coding tip
Confirm both anatomic sites and the phrase “without complications” in the assessment before assigning K50.80.
