ICD-10 Code J82.8 – Pulmonary eosinophilia, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J82.8 – Pulmonary eosinophilia, not elsewhere classified
What it is
J82.8 identifies pulmonary eosinophilia when the condition is not classified elsewhere. Use it for lung disease marked by eosinophil involvement, when documentation does not point to a more specific cause.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include cough, shortness of breath, and imaging abnormalities consistent with eosinophilic lung involvement.
When to use this code
Use J82.8 when the provider documents pulmonary eosinophilia and does not specify an underlying disorder or alternate diagnosis. It may apply when the record states eosinophilic lung disease, eosinophilic pneumonia, or similar wording without a more precise category. Check documentation if another condition explains the eosinophilia.
Do not use for
Do not use this code when eosinophilia is due to a clearly identified cause elsewhere classified. Also avoid it if the documentation supports a different lung diagnosis or a systemic eosinophilic disorder.
Coding tip
Code the most specific documented cause first; use J82.8 only when pulmonary eosinophilia stands alone.
