Other bacterial foodborne intoxications, not elsewhere classified (A05) ICD-10-CM
The A05 code range covers other bacterial foodborne intoxications, not elsewhere classified with 9 ICD-10-CM diagnosis codes. 8 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
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.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the A05 range.
Botulism
A disease caused by potent protein NEUROTOXINS produced by CLOSTRIDIUM BOTULINUM which interfere with the presynaptic release of ACETYLCHOLINE at the NEUROMUSCULAR JUNCTION. Clinical features include abdominal pain, vomiting, acute PARALYSIS (including respiratory paralysis), blurred vision, and DIPLOPIA. Botulism may be classified into several subtypes (e.g., food-borne, infant, wound, and others). (From Adams et al., Principles of Neurology, 6th ed, p1208)
About the A05 Code Range
These foodborne intoxications are forms of bacterial food poisoning grouped with intestinal infectious diseases.
The subdivisions distinguish staphylococcal intoxication (A05.0), botulism food poisoning (A05.1), and Clostridium perfringens intoxication (A05.2). Others name Vibrio parahaemolyticus (A05.3), Bacillus cereus (A05.4), or Vibrio vulnificus (A05.5). The remaining subdivisions distinguish other specified bacterial foodborne intoxications (A05.8) from unspecified ones (A05.9).
