J84.0: Alveolar and parietoalveolar conditions

Alveolar and parietoalveolar conditions, denoted by ICD-10 code J84.0, refer to medical problems that affect the tiny air sacs in your lungs, known as alveoli. When healthy, these alveoli fill with air as you breathe, allowing oxygen to pass into your blood. However, in these conditions, the alveoli become damaged or diseased, hampering their ability to function properly. A wide range of issues can cause this, such as infections, reactions to certain drugs, a poor immune system, or exposure to harmful substances like tobacco smoke. Affected individuals may experience symptoms like breathlessness, coughing, and weight loss. As the condition progresses, it can lead to more serious complications and can impact the respiratory system severely.
