Billable

Foodborne Bacillus cereus 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 toxins produced by Bacillus cereus bacteria, typically from eating contaminated food. Symptoms usually include nausea, vomiting, and abdominal cramps that develop after eating the contaminated food.

Coding Tips

  • Verify documentation specifies foodborne transmission and Bacillus cereus as the causative organism; do not use this code for other types of bacterial gastroenteritis
  • This code represents intoxication (toxin-mediated illness) rather than infection, so ensure clinical documentation supports toxin exposure rather than bacterial invasion
