Malignant neoplasm of upper lobe, bronchus or lung

This code signifies a cancerous tumor originating in the upper lobe of the lung or within the bronchus supplying that lobe. It indicates a primary malignancy, meaning the cancer started in this location rather than spreading from another site.

Apply this code when documentation clearly states a primary malignant neoplasm of the upper lobe of the lung, the upper lobar bronchus, or a main bronchus where the tumor is specifically located in the upper portion. Supporting pathology reports confirming malignancy and site specificity are crucial.

• Differentiate between primary and secondary (metastatic) lung cancer; this code is for primary only.
• Ensure the documentation specifies "upper lobe" or a bronchus clearly associated with the upper lobe.
• Avoid using this code for unspecified lung cancer or malignancies of other lung lobes.
