AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2020 Issue 4; New/Revised ICD-10-CM Codes
Pulmonary Eosinophilic Diseases
New subcategory J82.8, Pulmonary eosinophilia, not elsewhere classified, has been created with unique codes to identify certain pulmonary eosinophilic diseases. These new codes describe chronic eosinophilic pneumonia (J82.81), acute eosinophilic pneumonia (J82.82), eosinophilic asthma (J82.83), and other pulmonary eosinophilia, not elsewhere classified (J82.89). There are two types of eosinophilic pneumonia, acute and chronic. While both are characterized by eosinophil invasion of the lung tissue, the clinical presentation is quite different. Acute eosinophilic pneumonia (AEP) is classified as a form of eosinophilic lung disease, one of a large group of interstitial lung diseases. AEP...

Article Overview
This article explains a new ICD-10-CM subcategory for pulmonary eosinophilia and discusses the clinical differences among acute eosinophilic pneumonia, chronic eosinophilic pneumonia, and eosinophilic asthma. It is useful for coders, CDI specialists, and respiratory-focused clinicians who need to understand how these conditions are categorized and why they matter in documentation. The article also provides general guidance on asthma classification and includes a coding-oriented example tied to an exacerbation scenario.
Why This Topic Matters
Pulmonary eosinophilic diseases can look similar clinically but are categorized differently in ICD-10-CM. Accurate documentation and understanding of the new subcategory help support complete disease reporting and consistent coding for respiratory care.
