Farmer's lung
ICD-10 J67.0 is a billable code used to indicate a diagnosis of farmer's lung.
Farmer's lung is a type of hypersensitivity pneumonitis caused by the inhalation of organic dust, particularly moldy hay or grain, which leads to an immune response in the lungs. Clinically, patients may present with symptoms such as cough, dyspnea, fever, and malaise, often following exposure to the offending antigen. The disease primarily affects the alveoli and interstitial lung tissue, leading to inflammation and, in chronic cases, fibrosis. Disease progression can vary; acute episodes may resolve with avoidance of exposure, while chronic exposure can lead to irreversible lung damage. Diagnostic considerations include a thorough patient history, identification of exposure sources, and imaging studies such as chest X-rays or CT scans, which may show ground-glass opacities or reticular patterns. Serological tests for specific IgG antibodies against the offending antigens can further support the diagnosis. Early recognition and intervention are crucial to prevent long-term complications.

J67.0 specifically covers Farmer's lung, a form of hypersensitivity pneumonitis due to organic dust exposure, particularly in agricultural settings. It is characterized by an immune response leading to lung inflammation.
J67.0 should be used when the diagnosis is specifically Farmer's lung due to exposure to moldy hay or grain. It is differentiated from other hypersensitivity pneumonitis codes by the specific exposure history.
Documentation should include a detailed occupational history, evidence of exposure to moldy organic material, clinical symptoms, imaging results, and serological test results indicating hypersensitivity.
