Maltworker's lung
ICD-10 J67.4 is a billable code used to indicate a diagnosis of maltworker's lung.
Maltworker's lung, classified under J67.4, is a type of hypersensitivity pneumonitis caused by inhalation of organic dust, specifically from malted barley. Clinically, it presents with symptoms such as cough, dyspnea, and chest tightness, often exacerbated by exposure to malt dust. The disease primarily affects the lungs, leading to inflammation and potential fibrosis if exposure continues. The progression of maltworker's lung can vary; acute cases may resolve with avoidance of exposure, while chronic cases can lead to irreversible lung damage. Diagnostic considerations include a thorough occupational history, pulmonary function tests, and imaging studies such as chest X-rays or CT scans, which may reveal ground-glass opacities or reticular patterns indicative of interstitial lung disease. Serological tests for specific IgG antibodies against malt antigens may also aid in diagnosis. Early recognition and intervention are crucial to prevent long-term respiratory complications.

J67.4 specifically covers hypersensitivity pneumonitis due to exposure to malt dust, characterized by respiratory symptoms following occupational exposure.
J67.4 should be used when the diagnosis is specifically linked to malt dust exposure, distinguishing it from other types of hypersensitivity pneumonitis or lung conditions.
Documentation should include a detailed occupational history, symptom onset related to exposure, results from pulmonary function tests, and imaging findings consistent with hypersensitivity pneumonitis.
