ICD-10 Code K52.89 – Other specified noninfective gastroenteritis and colitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K52.89 – Other specified noninfective gastroenteritis and colitis
What it is
K52.89 identifies noninfective inflammation of the stomach or intestines that does not fit a more specific ICD-10 category. Use it when the provider documents a named noninfectious gastroenteritis or colitis and no other code is more accurate.
Clinical signs
Common findings include abdominal pain, diarrhea, nausea, and sometimes vomiting. Clinical features vary; refer to documentation for the specific noninfectious cause or pattern described by the provider.
When to use this code
Use K52.89 when the record clearly states other specified noninfective gastroenteritis or colitis, or a comparable noninfectious inflammatory bowel condition not otherwise classified. It may apply when the cause is documented but no dedicated code exists. Check documentation if the note is vague or incomplete.
Do not use for
Do not use this code for infectious gastroenteritis, ulcerative colitis, Crohn disease, or unspecified diarrhea alone. If the condition is better described by another code, choose that code instead.
Coding tip
Look for the provider’s exact wording and code the most specific noninfective diagnosis documented.
