Mushroom-worker's lung
ICD-10 J67.5 is a billable code used to indicate a diagnosis of mushroom-worker's lung.
Mushroom-worker's lung, classified under the category of hypersensitivity pneumonitis, is a respiratory condition resulting from prolonged exposure to organic dust, particularly from mushroom cultivation. Clinically, patients may present with symptoms such as cough, dyspnea, and chest tightness, often exacerbated by continued exposure to the allergen. The condition primarily affects the alveoli and bronchioles, leading to inflammation and potential fibrosis if exposure persists. Disease progression can vary; acute episodes may resolve with avoidance of the allergen, while chronic exposure 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 to assess lung involvement. Serological tests may also be employed to identify specific IgG antibodies against mushroom antigens, aiding in diagnosis.

J67.5 specifically covers hypersensitivity pneumonitis due to exposure to mushroom dust, characterized by immune-mediated lung inflammation. It is important to differentiate it from other forms of hypersensitivity pneumonitis caused by different organic dusts.
J67.5 should be used when the patient's respiratory condition is directly linked to occupational exposure to mushroom dust, as opposed to other organic dusts or non-occupational causes of lung disease.
Documentation should include a detailed occupational history, evidence of exposure to mushroom dust, clinical symptoms, results from pulmonary function tests, and any imaging studies that support the diagnosis of mushroom-worker's lung.
