Listeriosis (A32)
The ICD-10 codes starting with A32 are designated for various forms of listeriosis, an infection caused by the bacterium Listeria monocytogenes. These codes cover specific clinical presentations such as meningitis, sepsis, and skin infections.
The ICD-10 code for listeriosis includes a range of conditions. A32.0 identifies cutaneous listeriosis, a skin infection. Codes A32.1, A32.11, and A32.12 relate to listerial meningitis and meningoencephalitis, with A32.11 specifying Listeria meningitis and A32.12 covering meningoencephalitis, sometimes called bacterial meningoencephalitis. A32.7 is used for listerial sepsis, often described as sepsis caused by Listeria. Other forms, like oculoglandular listeriosis (A32.81) or listerial endocarditis (A32.82), also have specific codes. The code A32.9 covers unspecified listeriosis, which might include various presentations such as food poisoning or infections linked to miscarriage. Using these codes helps accurately classify the diverse and sometimes complex manifestations of listeriosis for medical records and coding.

Instructional Notations
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- listerial foodborne infection
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.
- neonatal disseminated listeriosis P37.2
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.
Listeria
A genus of bacteria which may be found in the feces of animals and man, on vegetation, and in silage. Its species are parasitic on cold-blooded and warm-blooded animals, including man.
Listeriosis
Infections with bacteria of the genus LISTERIA.
