Clinical Classification Guidelines
Medical Intelligence & Overview
Other forms of listeriosis, classified under ICD-10 code A32.8, refer to uncommon or atypical infections caused by the bacterium Listeria monocytogenes. Unlike the more typical gastrointestinal illness associated with listeriosis, these cases may involve different organ systems or manifest with varied symptoms. Recognizing and understanding these less common forms are vital for appropriate diagnosis and management, especially in vulnerable populations such as pregnant women, newborns, elderly, and immunocompromised individuals.
