Pulmonary eosinophilia, not elsewhere classified (J82) ICD-10-CM
The J82 code range covers pulmonary eosinophilia, not elsewhere classified with 6 ICD-10-CM diagnosis codes. 4 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the J82 Code Range
ICD-10 code J82
These codes are used to document disorders where eosinophils accumulate in the lungs, causing symptoms such as coughing and difficulty breathing. For example, J82.81 corresponds to chronic eosinophilic pneumonia, also known as cryptogenic pulmonary eosinophilia or idiopathic chronic eosinophilic pneumonitis, while J82.82 identifies acute eosinophilic pneumonia, sometimes called idiopathic eosinophilic pneumonitis. J82.83 is used for eosinophilic asthma, which may be referred to as asthmatic pulmonary eosinophilia. The code J82.89 captures other less common eosinophilic lung diseases, including allergic bronchopulmonary mycosis and tropical pulmonary eosinophilia. Recognizing these ICD-10 codes helps healthcare providers accurately classify and treat these specific eosinophil-related lung conditions.
