ICD-10 Code K50.018 – Crohn’s disease of small intestine with other complication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K50.018 – Crohn’s disease of small intestine with other complication
What it is
This code identifies Crohn’s disease affecting the small intestine when the record documents an additional complication that is not named elsewhere in the code set. Use it only when the site and complication are both supported by the chart.
Clinical signs
Clinical features vary; refer to documentation. Common findings in Crohn’s disease include chronic abdominal pain, diarrhea, weight loss, and evidence of inflammatory bowel disease involving the small bowel.
When to use this code
Use K50.018 when the provider documents Crohn’s disease of the small intestine and also specifies another complication, such as an issue not captured by a more specific Crohn’s code. This code fits inpatient, outpatient, and problem-list documentation when the complication is clearly linked. If the complication is not stated, check documentation before coding.
Do not use for
Do not use this code for Crohn’s disease limited to another intestinal site or when the record does not identify a qualifying complication. Do not guess the complication; check documentation.
Coding tip
Verify both the small-intestine location and the documented complication before assigning K50.018.
