A05.0 is a billable and specific ICD-10-CM code. Accurate documentation of A05.0 facilitates proper diagnosis, effective management, and correct reimbursement.
This guideline will provide the use, official coding guidelines, and historical background of A05.0.
What is the ICD-10-CM Diagnosis Code for Foodborne staphylococcal intoxication?
The ICD-10-CM diagnosis code for Foodborne Staphylococcal Intoxication is A05.0.
Foodborne Staphylococcal Intoxication is a type of food poisoning caused by eating food containing toxins from the Staphylococcus aureus bacteria.
These toxins can survive cooking and make you sick. It often happens when food is not stored or handled properly.
Proper documentation using A05.0 ensures patients receive appropriate care and enables accurate healthcare reimbursement.
Synonyms

- Staphylococcal food poisoning
History Background of ICD-10-CM Diagnosis Code A05.0
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 Foodborne Staphylococcal Intoxication is 005.1 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 Foodborne Staphylococcal Intoxication.
The 2025 edition of ICD-10-CM A05.0 became effective on October 1, 2024.

How Foodborne Staphylococcal Intoxication is Caused
- Consumption of food contaminated with Staphylococcus aureus
- Bacteria produce toxins that survive cooking
- Toxins often result from improper handling or storage of food
- Common in dairy products, meats, salads, and cream-filled pastries
