Malignant neoplasm of upper lobe, left bronchus or lung

This code signifies a primary cancerous tumor originating in the upper lobe of the left lung or the left main bronchus. This malignancy is characterized by uncontrolled cell growth and has the potential to invade surrounding tissues and metastasize.

This code is appropriate for patients diagnosed with a primary malignant neoplasm specifically located in the upper lobe of the left lung or the left bronchus. Documentation should clearly specify the primary nature of the tumor and its precise anatomical location within the left upper lobe or bronchus.

• Differentiate between primary and secondary (metastatic) lung cancers; this code is for primary only.
• Ensure the laterality (left) and specific lobe (upper) are clearly documented to support this granular code.
• Avoid using this code for unspecified lung locations or other lobes; more specific codes exist for those scenarios.
