ICD-10 Code K50.9 – Crohn’s disease, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K50.9 – Crohn’s disease, unspecified
What it is
K50.9 identifies Crohn’s disease when the chart does not specify the affected site or type. It is an inflammatory bowel disease that can involve any part of the gastrointestinal tract.
Clinical signs
Clinical features vary; refer to documentation. Common findings include chronic abdominal pain, diarrhea, weight loss, and evidence of intestinal inflammation or complications such as strictures, fistulas, or perianal disease.
When to use this code
Use K50.9 when the provider documents Crohn’s disease but does not identify a more specific location or subtype. It is appropriate for encounters where the diagnosis is established and no further detail is available in the record. If the note later specifies a site, code the more precise option instead.
Do not use for
Do not use this code for ulcerative colitis, infectious colitis, or nonspecific abdominal pain without a Crohn’s diagnosis. Check documentation if the record names a specific Crohn’s site or complication.
Coding tip
Query for the involved intestinal segment when the chart says only “Crohn’s disease,” because a more specific code may be available.
