ICD-10 Code K50.91 – Crohn’s disease, unspecified, with complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K50.91 – Crohn’s disease, unspecified, with complications
What it is
K50.91 identifies Crohn’s disease when the site is not specified and the record also documents complications. Use it when the chart confirms Crohn’s disease but does not name a more specific intestinal location.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include abdominal pain, diarrhea, weight loss, and evidence of inflammatory complications such as obstruction, fistula, abscess, or bleeding.
When to use this code
Use this code when the provider documents Crohn’s disease with complications, but the affected site is not specified in the note. It fits encounters where the complication is present and clearly linked to Crohn’s disease. If the record names a more specific Crohn’s code, code that instead.
Do not use for
Do not use K50.91 for Crohn’s disease without complications or when the documentation specifies a different Crohn’s site. Check documentation if the complication is unrelated or not clearly attributed to Crohn’s disease.
Coding tip
Look for both the Crohn’s diagnosis and the complication in the same record, and code the highest level of specificity supported.
