ICD-10 Code A32.0 – Cutaneous listeriosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A32.0 – Cutaneous listeriosis
What it is
This code identifies Listeria infection limited to the skin. Use it when documentation states cutaneous listeriosis or a skin lesion caused by Listeria.
Clinical signs
Findings may include localized skin inflammation, papules, pustules, or ulcerated lesions after exposure or inoculation. Clinical features vary; refer to documentation.
When to use this code
Use A32.0 when the provider documents cutaneous listeriosis, Listeria skin infection, or a localized skin manifestation due to Listeria. It may apply when the infection is confined to the skin and not described as septic or systemic. Check documentation if the record mentions broader listeriosis.
Do not use for
Do not use this code for generalized listeriosis, meningitis, or other noncutaneous Listeria infections. If the site or extent is unclear, check documentation.
Coding tip
Confirm that the record specifies a skin-only Listeria infection before assigning A32.0.
