Food poisoning due to Clostridium perfringens (C. welchii)

This code identifies foodborne illness specifically caused by Clostridium perfringens. It represents an acute gastroenteritis resulting from the ingestion of food contaminated with the bacteria, often characterized by abdominal cramps and diarrhea.

Apply this code when documentation clearly indicates a diagnosis of food poisoning attributed to Clostridium perfringens. This typically occurs following consumption of improperly cooked or reheated meats and poultry. Supporting documentation would include physician notes detailing symptoms and a confirmed or suspected etiology.

• Ensure the documentation specifies Clostridium perfringens as the causative agent; do not use for general food poisoning without a specified organism.
• Consider sequencing this code as the primary diagnosis if it is the reason for the encounter.
• Review for any associated dehydration or other complications that may require additional codes.
