ICD-10 Code K50.814 – Crohn’s disease of both small and large intestine with abscess (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K50.814 – Crohn’s disease of both small and large intestine with abscess
What it is
This code identifies Crohn’s disease affecting both the small and large intestine, with an abscess present. It reflects a documented inflammatory bowel disease complication rather than uncomplicated Crohn’s disease.
Clinical signs
Typical findings include chronic abdominal pain, diarrhea, weight loss, and evidence of intestinal inflammation. Clinical features vary; refer to documentation for the abscess location and whether it is intra-abdominal, perianal, or otherwise specified.
When to use this code
Use K50.814 when the record clearly states Crohn’s disease involving both small and large intestine and also documents an abscess. You should code it when the provider links the abscess to Crohn’s disease or describes Crohn’s with abscess complications. Check documentation if the site or relationship is unclear.
Do not use for
Do not use this code for Crohn’s disease without an abscess, or when the disease involves only the small or only the large intestine. Do not assume abscess coding if the chart does not specifically document it.
Coding tip
Verify both the bowel location and the abscess in the provider note before assigning K50.814.
