Pulmonary eosinophilia, not elsewhere classified (J82)
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.

Instructional Notations
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.

- pulmonary eosinophilia due to drugs J70.2 J70.4
- pulmonary eosinophilia due to specified parasitic infection B50 B83
- pulmonary eosinophilia due to systemic connective tissue disorders M30 M36

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Eosinophils
Granular leukocytes with a nucleus that usually has two lobes connected by a slender thread of chromatin, and cytoplasm containing coarse, round granules that are uniform in size and stainable by eosin.
Pulmonary Eosinophilia
A condition characterized by infiltration of the lung with EOSINOPHILS due to inflammation or other disease processes. Major eosinophilic lung diseases are the eosinophilic pneumonias caused by infections, allergens, or toxic agents.
