Other specified interstitial pulmonary diseases
ICD-10 J84.8 is a used to indicate a diagnosis of other specified interstitial pulmonary diseases.
J84.8 refers to 'Other specified interstitial pulmonary diseases,' which encompasses a variety of lung conditions characterized by inflammation and scarring of the lung interstitium. Clinically, patients may present with symptoms such as progressive dyspnea, chronic cough, and fatigue. The anatomy involved primarily includes the alveoli and surrounding connective tissue, which become thickened and fibrotic, impairing gas exchange. Disease progression can vary widely; some patients may experience a gradual decline in lung function, while others may have acute exacerbations. Diagnostic considerations include high-resolution computed tomography (HRCT) scans, pulmonary function tests, and sometimes lung biopsy to differentiate between various interstitial lung diseases (ILDs). It is crucial to identify the underlying cause, as treatment options may differ significantly based on etiology, which can include autoimmune diseases, environmental exposures, or idiopathic origins.

J84.8 includes various interstitial lung diseases not classified elsewhere, such as hypersensitivity pneumonitis, sarcoidosis, and drug-induced lung disease. Each condition has specific diagnostic criteria that must be met for accurate coding.
J84.8 should be used when the interstitial lung disease does not fit into more specific categories, such as idiopathic pulmonary fibrosis or sarcoidosis, and when the specific cause is unknown or not documented.
Documentation should include clinical findings, imaging results (such as HRCT), pulmonary function tests, and any relevant laboratory results that support the diagnosis of an unspecified interstitial lung disease.
