Lung disease ICD codes should be used when a healthcare provider diagnoses a condition affecting the lungs or respiratory system, including both acute and chronic disorders. These codes help document conditions like COPD, pneumonia, pulmonary fibrosis, and other interstitial or obstructive lung diseases for billing, treatment planning, and health record accuracy.

Treatment for lung diseases varies depending on the diagnosis code but commonly includes medications (e.g., bronchodilators, corticosteroids), oxygen therapy, pulmonary rehabilitation, and lifestyle changes like smoking cessation. For advanced or progressive conditions such as pulmonary fibrosis or cystic lung disease, surgical interventions or lung transplants may also be considered.

A diagnosis code for lung disease indicates the specific respiratory condition a patient has, based on clinical evaluation, imaging, and test results. These ICD-10 codes provide essential information for healthcare documentation, insurance claims, and tracking patient outcomes.
