ICD-10 Code K52.8 – Other specified noninfective gastroenteritis and colitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K52.8 – Other specified noninfective gastroenteritis and colitis
What it is
K52.8 identifies noninfective inflammation of the stomach and intestines that does not fit a more specific diagnosis. Use it when documentation names another specified noninfective gastroenteritis or colitis.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include diarrhea, abdominal pain, and bowel inflammation, but the cause is not infectious.
When to use this code
Use K52.8 when the provider documents a specific noninfective gastroenteritis or colitis that is not classified elsewhere. It can support cases described as other specified, atypical, or otherwise named noninfective intestinal inflammation. If the record only says gastroenteritis or colitis without more detail, check documentation.
Do not use for
Do not use this code for infectious gastroenteritis, ulcerative colitis, Crohn disease, or nonspecific colitis that has a more precise code. Check documentation if the cause or subtype is unclear.
Coding tip
Code K52.8 only when the chart clearly supports a specified noninfective condition and no more specific ICD-10-CM code applies.
