ICD-10 Code A32.8 – Other forms of listeriosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A32.8 – Other forms of listeriosis
What it is
A32.8 identifies listeriosis presentations caused by Listeria infection that do not fit the more specific ICD-10 categories. Use it when documentation confirms listeriosis, but the chart does not specify another coded form.
Clinical signs
Clinical features vary; refer to documentation. Listeriosis may present with fever, gastrointestinal illness, sepsis, or central nervous system involvement, but you should code only the documented form.
When to use this code
Use A32.8 when the provider documents listeriosis and the record does not support a more specific listeria code. It is appropriate for confirmed “other” or unspecified forms that are not classified elsewhere.
If the note describes a distinct manifestation, such as meningitis or neonatal disease, choose the more specific code instead. Check documentation carefully for the exact clinical diagnosis and any stated site or complication.
Do not use for
Do not use this code for non-listeria infections or for listeriosis forms that have their own ICD-10 code. If the documentation is unclear, check documentation rather than assuming A32.8.
Coding tip
Assign the most specific listeriosis code supported by the record, and use A32.8 only when the provider’s documentation is confirmed but nonspecific.
