Other bacterial foodborne intoxications, not elsewhere classified (A05)
The ICD-10 section A05 covers various bacterial foodborne intoxications that are not classified elsewhere, representing specific types of food poisoning caused by bacteria. These codes help identify distinct bacterial causes related to contaminated food.
This section includes A05.0 for staphylococcal food poisoning, often referred to as Staphylococcus aureus food poisoning. A05.1 codes for botulism food poisoning, linked to toxins from Clostridium botulinum. Other codes identify intoxications from bacteria such as A05.2 for Clostridium perfringens, A05.3 for Vibrio parahaemolyticus, A05.4 for Bacillus cereus, and A05.5 for Vibrio vulnificus. The A05.8 code includes other specified bacterial causes like Escherichia coli and Listeria monocytogenes. When the bacterial source is unknown, A05.9 is used to classify unspecified bacterial food poisoning. Understanding these distinctions is crucial for accurate documentation of diagnosis and treatment related to bacterial foodborne illnesses.

Instructional Notations
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- Clostridium difficile foodborne intoxication and infection A04.7
- Escherichia coli infection A04.0 A04.4
- listeriosis A32
- salmonella foodborne intoxication and infection A02
- toxic effect of noxious foodstuffs T61 T62
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Clostridium perfringens
The most common etiologic agent of GAS GANGRENE. It is differentiable into several distinct types based on the distribution of twelve different toxins.
Enterotoxemia
Disease caused by the liberation of exotoxins of CLOSTRIDIUM PERFRINGENS in the intestines of sheep, goats, cattle, foals, and piglets. Type B enterotoxemia in lambs is lamb dysentery; type C enterotoxemia in mature sheep produces struck, and in calves, lambs and piglets it produces hemorrhagic enterotoxemia; type D enterotoxemia in sheep and goats is pulpy-kidney disease or overeating disease.
