A08.39

What This Code Means

This code describes inflammation of the small intestine caused by a virus that is not one of the more common types like rotavirus or norovirus. It typically causes symptoms like diarrhea, nausea, and abdominal discomfort.

Coding Tips

• •Use this code only when the specific viral cause of enteritis is documented but does not fit into the more specific subcategories (A08.0-A08.32)
• •Ensure the documentation clearly indicates viral etiology rather than bacterial or parasitic causes, and verify that a more specific viral enteritis code is not applicable before assigning A08.39
