Malignant neoplasm of supraglottis

This code signifies a cancerous tumor originating in the supraglottis, the upper portion of the larynx above the vocal cords. This area includes structures such as the epiglottis, aryepiglottic folds, and false vocal cords. The malignancy is characterized by uncontrolled cell growth within these laryngeal tissues.

Assign this code when documentation confirms a primary malignant neoplasm located specifically within the supraglottic region of the larynx. This diagnosis is typically established through biopsy and histopathological examination. Use this code for initial encounters, subsequent treatment, or follow-up for this specific cancer.

• Differentiate carefully from malignancies of the glottis or subglottis; anatomical specificity is crucial.
• Ensure the pathology report explicitly states "supraglottis" as the primary site of the malignancy.
• Do not use for benign neoplasms or secondary metastatic lesions to the supraglottis.
