ICD-10 Code A32.7 – Listerial Sepsis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A32.7 – Listerial sepsis
What it is
A32.7 identifies sepsis caused by Listeria species, most often Listeria monocytogenes. Use it when documentation states listerial sepsis or sepsis due to Listeria infection.
Clinical signs
Clinical features vary; refer to documentation. Typical sepsis findings may include systemic infection with fever or hypothermia, altered mental status, and signs of organ dysfunction.
When to use this code
Use A32.7 when the provider documents sepsis due to Listeria, or when the record clearly links Listeria infection with sepsis. Code the documented organism and any additional manifestations if supported. Check documentation if the note only says bacteremia, meningitis, or infection without sepsis.
Do not use for
Do not use this code for uncomplicated listeriosis without sepsis, or for sepsis from another organism. If the diagnosis is uncertain or not specified, check documentation.
Coding tip
Confirm the provider explicitly connects sepsis to Listeria before assigning A32.7.
