BillableFoodborne Clostridium perfringens [Clostridium welchii] intoxication
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This is a type of food poisoning caused by bacteria called Clostridium perfringens that grow in improperly stored or cooked food. The bacteria produce toxins in the intestines that cause cramping and diarrhea, typically appearing 8-16 hours after eating contaminated food.
Coding Tips
- •This code is used when the patient has confirmed or suspected foodborne illness from C. perfringens; document the source of exposure (specific food item) when available to support medical necessity
- •Do not use this code for C. difficile infections (use A04.7x instead) or for non-foodborne clostridial infections; ensure the documentation clearly indicates the food-related transmission route
