What This Code Means
A24.2 is the ICD-10-CM diagnosis code for subacute and chronic melioidosis. Melioidosis is a serious bacterial infection caused by Burkholderia pseudomallei, commonly found in soil and water in tropical and subtropical regions. This code specifically refers to the slower-developing forms of the disease that persist over weeks to months. A24.2 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering certain zoonotic bacterial diseases (a20-a28).
A24.2 is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
Melioidosis is endemic to Southeast Asia and northern Australia; document the patient's travel history or geographic origin to support medical necessity.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for A24.2 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Melioidosis is endemic to Southeast Asia and northern Australia; document the patient's travel history or geographic origin to support medical necessity
- •Distinguish between acute (A24.1), subacute/chronic (A24.2), and other forms (A24.3, A24.4) based on symptom onset and disease progression timeline documented in the medical record
