Other and unspecified noninfectious gastroenteritis and colitis

This code represents inflammation of the stomach and intestines (gastroenteritis) or colon (colitis) that is not caused by an infectious agent. It encompasses a broad range of non-infectious etiologies, including allergic reactions, dietary indiscretions, or other unspecified irritants to the gastrointestinal tract.

Use this code when documentation indicates gastroenteritis or colitis without a specified infectious cause. This is appropriate for cases where the provider has ruled out bacterial, viral, or parasitic infections, or when the specific non-infectious etiology is not clearly identified.

• Avoid using this code if a more specific non-infectious cause, such as irritable bowel syndrome (IBS) or Crohn's disease, is documented.
• Ensure the medical record explicitly states "noninfectious" or provides sufficient detail to rule out an infectious origin.
• Consider sequencing this code after any underlying conditions that may be contributing to the gastroenteritis or colitis.
