What This Code Means

J82.82 is the ICD-10-CM diagnosis code for acute eosinophilic pneumonia. Sudden lung inflammation with an abnormal increase in eosinophils that develops rapidly, often causing acute breathing difficulty. J82.82 sits in the ICD-10-CM chapter for diseases of the respiratory system (j00-j99), within the section covering other respiratory diseases principally affecting the interstitium (j80-j84).

J82.82 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.

Document the acute onset and any identifiable trigger (medication, infection, environmental exposure) in the medical record.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for J82.82 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
