Other specified intestinal infections

This code signifies an intestinal infection caused by a pathogen not specifically classified elsewhere in the A00-A08 range. It covers various infectious agents that lead to gastrointestinal symptoms like diarrhea, vomiting, and abdominal pain, but which do not have a more precise ICD-10-CM code.

Apply this code when documentation clearly indicates an intestinal infection, and the causative organism is identified but lacks a more specific code (e.g., certain viral, bacterial, or parasitic infections not explicitly listed). This code is appropriate when the provider specifies "other specified intestinal infection" or provides a diagnosis that falls into this residual category.

• Always attempt to code to the highest level of specificity; only use this code when a more precise diagnosis code is unavailable.
• Review documentation for the specific infectious agent; if identified, search for a more granular code before resorting to this "other specified" option.
• Consider sequencing if the intestinal infection is a manifestation of a systemic disease; the underlying condition may be coded first.
