Other zoonotic bacterial diseases, not elsewhere classified (A28)

ICD-10 code section A28 covers other zoonotic bacterial diseases not classified elsewhere, addressing infections transmitted from animals to humans that do not fit into more specific categories. This includes diseases like pasteurellosis, cat-scratch disease, extraintestinal yersiniosis, and several other less common bacterial zoonoses.

This section is essential for coding infections caused by bacteria transmitted from animals when they are not otherwise specified. For example, A28.0 corresponds to pasteurellosis, also known by synonyms such as cat-bite fever or infection by Pasteurella multocida, which arises often from cat or dog bites. A28.1 identifies cat-scratch disease, sometimes called cat scratch disease without a dash. Meanwhile, A28.2 refers to extraintestinal yersiniosis, which may present as Masshoff's syndrome or erythema nodosum due to Yersinia enterocolitica. Code A28.8 includes various specified zoonotic bacterial infections, such as actinobacillosis from different Actinobacillus species. For infections that do not meet specific criteria, A28.9 covers unspecified zoonotic bacterial diseases. Using these codes helps accurately capture and document animal-to-human bacterial infections beyond commonly classified conditions.
