J84.1: Other interstitial pulmonary diseases with fibrosis

Interstitial pulmonary diseases with fibrosis, classified under the ICD-10 code J84.1, are a type of lung diseases where the inner tissue of your lungs, called interstitium, becomes inflamed and subsequently scarred or fibrotic. This fibrosis or scarring makes the lungs stiff and reduces their ability to expand and contract, thus affecting your ability to breathe. Common signs and symptoms include shortness of breath, persistent dry cough, weight loss, and fatigue. These conditions can be caused by various factors, including long-term exposure to hazardous materials, such as asbestos or coal dust, certain autoimmune diseases, like rheumatoid arthritis or sarcoidosis, and some medications or radiation treatments. Disease progression varies widely among individuals, ranging from slow progression over many years to rapid deterioration.
