About the J80–J84 Code Range
ICD-10 codes J80-J84 cover respiratory diseases primarily affecting the lung interstitium, a crucial tissue supporting lung function. These codes are used for conditions like acute respiratory distress, pulmonary edema, eosinophilic pneumonia, and various interstitial lung diseases involving fibrosis or inflammation.
This range includes J80 for acute respiratory distress syndrome, often called ARDS or known by synonyms such as postoperative pulmonary edema and acute respiratory distress due to vaping or COVID-19. Codes J81.0 and J81.1 specify acute and chronic pulmonary edema, conditions marked by fluid buildup in the lungs. Pulmonary eosinophilia, inflammation caused by eosinophils, is classified under J82, with subcodes documenting chronic and acute eosinophilic pneumonia and eosinophilic asthma. The J84 category addresses other interstitial lung disorders including idiopathic pulmonary fibrosis (J84.112), lymphoid interstitial pneumonia (J84.2), and rare diseases like lymphangioleiomyomatosis (J84.81). These codes help target complex lung diseases where tissue scarring, inflammation, or genetic defects impair breathing and oxygen exchange.
