ICD-10 Code A24.9 – Melioidosis, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A24.9 – Melioidosis, unspecified
What it is
A24.9 identifies melioidosis when the record does not specify the form or site of infection. Use it for a Burkholderia pseudomallei infection documented as melioidosis, unspecified.
Clinical signs
Clinical features vary; refer to documentation. Melioidosis may present with fever, pneumonia, skin abscesses, or sepsis, but the unspecified code only requires that melioidosis is recorded without further detail.
When to use this code
Use A24.9 when the provider documents melioidosis but does not identify a localized, pulmonary, or disseminated form. It also fits when the note confirms the diagnosis and no additional specificity is available. Check documentation if another infection site is described.
Do not use for
Do not use this code if the record specifies another melioidosis type or a different infectious diagnosis. If the chart only mentions exposure, testing, or suspected infection, you need supporting documentation.
Coding tip
Code the most specific melioidosis diagnosis available; if the provider leaves it nonspecific, A24.9 is the correct choice.
