J67.9: Hypersensitivity pneumonitis due to unspecified organic dust

Hypersensitivity pneumonitis due to unspecified organic dust is a type of lung inflammation resulting from inhaling certain types of dust particles. This condition occurs when your immune system reacts to these inhaled organic substances, which can include molds, bacteria, proteins, or chemicals present in the dust. Exposed occupations could include farming, bird breeding, or working in a humid environment. Symptoms generally resemble those of flu, such as fever, chills, cough, shortness of breath, and loss of weight, and typically appear 4-6 hours after exposure to the dust. This inflammation can cause scarring that later results in breathing issues and can affect other body systems over time. If left untreated, it can progress to cause permanent lung damage or even failure. But if the exposure is stopped early, the condition usually improves and might even go away completely.
