A05.9

Billable

Bacterial foodborne intoxication, unspecified

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

This code describes a bacterial infection acquired from contaminated food where the specific type of bacteria causing the illness is not identified or documented. It represents foodborne illness caused by bacterial toxins or organisms that were present in food.

Coding Tips

  • Use this code only when the specific bacterial organism (such as Salmonella, Staphylococcus aureus, or Clostridium) cannot be determined from the medical record or test results
  • If the specific bacterial pathogen is identified, use the more specific A05 subcodes (A05.0-A05.8) instead of the unspecified code A05.9
