Malignant neoplasm of right main bronchus

This code signifies a primary cancerous tumor originating in the right main bronchus, the large airway branching off the trachea into the right lung. This malignancy is characterized by uncontrolled cell growth within the bronchial wall.

Apply this code when documentation confirms a primary malignant neoplasm specifically located in the right main bronchus. This diagnosis is typically established through biopsy, imaging (e.g., CT scan, bronchoscopy), and pathology reports.

• Ensure the laterality is explicitly documented as "right" and the site as "main bronchus."
• Distinguish from secondary malignancies or benign neoplasms of the bronchus.
• Sequence according to the primary diagnosis guidelines, often as the principal diagnosis if it's the reason for the encounter.
