Benign neoplasm of bronchus and lung

This code represents a non-cancerous growth originating in the bronchial tree or lung tissue. These benign tumors are typically slow-growing and do not metastasize to other parts of the body, though they can cause symptoms due to their size or location.

Apply this code when documentation confirms a benign tumor of the bronchus or lung, often identified incidentally on imaging or during workup for respiratory symptoms. This diagnosis is typically established through biopsy and histopathological examination confirming its benign nature.

• Ensure the pathology report explicitly states "benign" for the neoplasm; otherwise, consider codes for uncertain behavior or malignancy.
• Do not use this code for metastatic lesions to the lung; those require codes for secondary malignancy.
• Distinguish from inflammatory pseudotumors or hamartomas, which may have specific codes or fall under this category if classified as benign neoplasms.
