Hypersensitivity pneumonitis due to unspecified organic dust
ICD-10 J67.9 is a billable code used to indicate a diagnosis of hypersensitivity pneumonitis due to unspecified organic dust.
Hypersensitivity pneumonitis (HP) due to unspecified organic dust is an inflammatory response in the lungs triggered by inhalation of organic dust, which can include mold, bacteria, or animal proteins. Clinically, patients may present with symptoms such as cough, dyspnea, fever, and malaise, often following exposure to the offending agent. The condition primarily affects the alveoli and bronchioles, leading to inflammation and, in chronic cases, fibrosis. Disease progression can vary; acute HP may resolve with avoidance of the trigger, while chronic HP can lead to irreversible lung damage. Diagnostic considerations include a thorough patient history, pulmonary function tests, imaging studies such as chest X-rays or CT scans, and sometimes bronchoalveolar lavage to identify specific antibodies or inflammatory markers. The absence of a specified organic dust source necessitates the use of J67.9, emphasizing the need for careful clinical evaluation to ascertain the underlying cause of the hypersensitivity reaction.

J67.9 covers hypersensitivity pneumonitis due to unspecified organic dust, which may include various allergens such as mold, animal dander, or other organic materials that provoke an immune response in the lungs.
J67.9 should be used when the specific organic dust causing hypersensitivity is unknown or not documented. If the specific agent is identified, a more specific code should be utilized.
Documentation should include a detailed patient history of exposure to organic dust, clinical symptoms, results from pulmonary function tests, and any imaging studies that support the diagnosis of hypersensitivity pneumonitis.
