ICD-10 Code J82.89 – Other pulmonary eosinophilia, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J82.89 – Other pulmonary eosinophilia, not elsewhere classified
What it is
J82.89 identifies pulmonary eosinophilia that affects the lungs but does not fit a more specific category. Use it when documentation describes eosinophilic lung involvement without another named cause or subtype.
Clinical signs
Clinical features vary; refer to documentation. Common references describe cough, shortness of breath, chest discomfort, and pulmonary infiltrates with eosinophilic involvement, but you should code only what is documented.
When to use this code
Use this code when the provider documents other or unspecified pulmonary eosinophilia and does not name a more specific diagnosis. It also fits cases where eosinophilic lung disease is confirmed, but the record does not support a different code. Check documentation for the exact pulmonary diagnosis.
Do not use for
Do not use this code for eosinophilia limited to blood or for a more specific pulmonary eosinophilic disorder already documented. If the chart names another defined condition, code that diagnosis instead.
Coding tip
Confirm that the record links eosinophilia to the lungs and that no more specific pulmonary diagnosis is documented.
