ICD-10-CM Code For Pulmonary Eosinophilia Not Elsewhere Classified: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group J82 includes pulmonary eosinophilia conditions characterized by eosinophilic infiltration of lung tissue, including acute and chronic eosinophilic pneumonias when not classified elsewhere. These ICD-10-CM diagnosis codes are used to document respiratory conditions with eosinophilic lung involvement, capturing disease distribution, severity, and related clinical complexity. Accurate coding within the ICD-10-CM J82 group supports complete clinical documentation and appropriate reimbursement.

ICD-10-CM J82: Pulmonary Eosinophilia, Not Elsewhere Classified Overview

This code group represents pulmonary eosinophilia syndromes characterized by eosinophilic infiltration of the lung interstitium and airspaces. It targets respiratory system conditions with prominent eosinophil-mediated inflammation and variable clinical presentations. Accurate coding supports complete clinical documentation and helps ensure appropriate reimbursement for services related to diagnosis and management.

When to Use

Use a code from this group when a clinical diagnosis documents pulmonary eosinophilia without a more specific alternative ICD-10-CM code. These codes apply when eosinophilic lung disease is confirmed by clinical, radiographic, or laboratory evidence and no other category describes the condition.

Typical Clinical Scenarios

A middle-aged patient presents to the emergency department with acute onset dyspnea, pleuritic chest pain, hypoxemia, and a peripheral eosinophilia after recent initiation of a new anti-parasitic medication; chest imaging shows new bilateral patchy pulmonary infiltrates consistent with acute eosinophilic lung involvement. The acute presentation following drug exposure leads to assignment of an eosinophilic pulmonary diagnosis in the setting of drug-related lung injury. Typical codes: J82.82
A young adult with a months-long history of nonproductive cough, progressive exertional dyspnea, night sweats, and intermittent peripheral eosinophilia undergoes high-resolution CT demonstrating chronic, diffuse ground-glass opacities and bronchoalveolar lavage showing eosinophil-predominant inflammation; no identifiable systemic cause is found. The chronic, idiopathic interstitial eosinophilic lung disease is coded to reflect ongoing pulmonary eosinophilia as the principal respiratory diagnosis. Typical codes: J82.81
An inpatient with known asthma is admitted for worsening respiratory failure and is found to have superimposed pulmonary eosinophilic infiltration on biopsy after persistent infiltrates despite treatment; the eosinophilic process is documented as a secondary respiratory comorbidity complicating the primary obstructive disease. A code from the eosinophilia group is assigned to capture the complicating interstitial eosinophilic involvement. Typical codes: J82.83, J82.89
