A05.3

What This Code Means

This is a foodborne illness caused by eating contaminated seafood or other foods containing Vibrio parahaemolyticus bacteria, which causes acute gastrointestinal symptoms like diarrhea, abdominal cramps, and vomiting. The infection typically develops within 24 hours of eating contaminated food and is usually self-limiting.

Coding Tips

• •This code should be used when there is documented evidence of Vibrio parahaemolyticus infection acquired through food consumption; do not use if the source of infection is unclear or non-foodborne
• •Code A05.3 is part of the foodborne intoxication category (A05), so ensure you are not confusing this with other Vibrio infections (such as A33 for Vibrio cholerae) or non-foodborne sources
