ICD-10 Code K50.812 – Crohn’s disease of both small and large intestine with intestinal obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K50.812 – Crohn’s disease of both small and large intestine with intestinal obstruction
What it is
K50.812 identifies Crohn’s disease affecting both the small and large intestine when the condition is complicated by intestinal obstruction. Use it for documented Crohn’s involvement across both sites with blockage or narrowing.
Clinical signs
Typical findings include chronic inflammatory bowel disease with abdominal pain, diarrhea, weight loss, and evidence of obstructive symptoms such as cramping, distention, vomiting, or decreased bowel output. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents Crohn’s disease in both the small and large intestine and also states intestinal obstruction. The obstruction may be described as partial or complete, but it must be linked to the Crohn’s diagnosis. If the record does not clearly specify both sites and obstruction, check documentation.
Do not use for
Do not use K50.812 for Crohn’s disease without obstruction, for disease limited to only small or only large intestine, or for obstruction from another cause. Check documentation.
Coding tip
Confirm both the anatomic involvement and the obstruction in the provider’s note before assigning this code.
