2025 ICD-10-CM code A08.8
(Active) Effective Date: N/A Infectious and parasitic diseases - Intestinal infectious diseases Certain infectious and parasitic diseases Feed
Other specified intestinal infections.
Medical necessity is established by the presence of signs and symptoms of intestinal infection, and confirmation of the diagnosis through appropriate diagnostic testing identifying an organism not classified elsewhere in the A00-A09 range.
Clinicians diagnose intestinal infections based on symptoms (diarrhea, vomiting, abdominal pain, fever, etc.), patient history, and physical exam. Lab tests of stool samples can help identify the infectious organism. Treatment usually involves rehydration (oral or intravenous fluids). Antibiotics may be prescribed for bacterial infections, but are ineffective against viruses. Patient education on preventive measures, like handwashing and food safety, is crucial.
- Certain infectious and parasitic diseases
- A00-B99, Certain infectious and parasitic diseasesA00-A09, Intestinal infectious diseases
In simple words: This code is used when a person has an infection in their intestines caused by a microorganism not specifically listed elsewhere, such as certain bacteria, viruses, or parasites. It does not include the flu with stomach or intestinal issues.
Other specified intestinal infections. This code excludes influenza with involvement of the gastrointestinal tract (J09.X3, J10.2, J11.2).
Example 1: A patient presents with persistent diarrhea, abdominal cramps, and fever. Stool culture reveals Clostridium difficile, not covered by other A0 codes., A child experiences vomiting and watery diarrhea after consuming contaminated food. Lab tests identify an unusual strain of E. coli, not specified in other codes., A traveler returning from abroad reports severe diarrhea and dehydration. After ruling out other common causes, a rare intestinal parasite is identified through microscopic examination of stool, requiring use of A08.8.
Documentation should include signs and symptoms, duration of illness, travel history (if relevant), laboratory findings identifying the causative organism (e.g., stool culture, microscopy), and treatment provided.
