Other forms of listeriosis

This code signifies listeriosis infections that do not manifest as meningitis, meningoencephalitis, or cerebral listeriosis. It encompasses various systemic or localized infections caused by Listeria monocytogenes affecting organs other than the central nervous system. Examples include listerial bacteremia, endocarditis, or localized abscesses.

Use this code when documentation specifies a confirmed Listeria monocytogenes infection that is not explicitly coded elsewhere (e.g., A32.1 for meningitis). This code is appropriate for cases like listerial sepsis without CNS involvement, listerial gastroenteritis, or listerial infections of the skin or eyes. Documentation should clearly identify Listeria as the causative agent and rule out CNS involvement.

• Do not use this code if the documentation indicates listerial meningitis or meningoencephalitis; refer to codes within A32.1.
• Always confirm the specific site of infection from the medical record to ensure accurate coding.
• Consider sequencing this code as a primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it complicates another condition.
