What is the ICD-10-CM Diagnosis Code for Other specified bacterial foodborne intoxications?
The ICD-10-CM diagnosis code for Other specified bacterial foodborne intoxications is A05.8.
Foodborne intoxication occurs when toxins produced by bacteria, viruses, or molds contaminate food, leading to illness.
Other specified bacterial foodborne intoxication refers to food poisoning caused by bacterial toxins not classified under common pathogens like Clostridium botulinum or Staphylococcus aureus. It includes rare bacterial toxins that trigger nausea, vomiting, diarrhea, and abdominal pain.

History Background of ICD-10-CM Diagnosis Code A05.8
The ICD-9-CM system, first introduced in 1979, provided the initial framework for coding diseases and health-related conditions in the United States.
The ICD-9-CM diagnosis code for Other specified bacterial foodborne intoxications is 005.89.This coding remained consistent from 1979 to 2015.
While the ICD-9-CM system offered a basic approach to disease classification, modern healthcare needs more detail and specificity.
To address this, the ICD-10-CM system was launched in 2015, introducing a more comprehensive and accurate coding structure.
The transition from ICD-9-CM to ICD-10-CM significantly improved the ability to document and analyze conditions such as Other specified bacterial foodborne intoxications.
The 2025 edition of ICD-10-CM A05.8 became effective on October 1, 2024.
