    ICD-10-CM Code For Listeriosis: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group A32 includes invasive infections caused by Listeria species, such as septicemia, meningitis, and infections associated with pregnancy and the newborn. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving systemic listerial infection, central nervous system involvement, or pregnancy-related complications that affect treatment and outcomes. Accurate coding within the ICD-10-CM A32 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM A32: Listeriosis Overview

    The ICD-10-CM A32 group represents infections caused by Listeria species, primarily Listeria monocytogenes, affecting systems such as the central nervous system, bloodstream, and pregnancy-related tissues. These diagnoses target invasive bacterial disease presentations including septicemia, meningitis, and infections complicating pregnancy and the newborn. Accurate coding matters for complete clinical records and appropriate reimbursement because it reflects disease severity, organ involvement, and complications that affect care and payment.

    Typical Clinical Scenarios

    • A pregnant woman in her second trimester presents with fever, myalgias, and decreased fetal movements after consuming unpasteurized dairy; blood cultures grow Listeria monocytogenes and she is started on targeted antibiotics to prevent fetal infection. A diagnosis from this group is assigned to capture systemic maternal listerial infection with obstetric risk. Typical codes: A32.1,A32.11
    • An elderly nursing home resident develops sudden confusion, high fever, neck stiffness, and positive cerebrospinal fluid culture for Listeria, prompting hospital admission to the ICU for management of bacterial meningitis. A code from this group is used to document Listeria encephalitis/meningitis as the acute central nervous system infection driving care. Typical codes: A32.0,A32.11
    • A neonate presents within the first week of life with respiratory distress, sepsis-like picture, and blood cultures positive for Listeria; the infant requires neonatal intensive care and prolonged antibiotic therapy for invasive listeriosis. A diagnosis code from this group is assigned to indicate neonatal systemic listerial infection and guide inpatient management coding. Typical codes: A32.82,A32.81
