Malignant neoplasm of laryngeal cartilage

This code signifies the presence of a cancerous tumor originating in the cartilaginous structures of the larynx, such as the thyroid, cricoid, or arytenoid cartilages. This malignancy can affect voice production, breathing, and swallowing due to its location within the voice box.

Apply this code when documentation explicitly states a primary malignant neoplasm of any laryngeal cartilage. This diagnosis is typically confirmed through biopsy and histopathological examination. Use this code for the initial encounter for treatment of the primary site.

• Differentiate from squamous cell carcinoma of other laryngeal sites (e.g., glottis, supraglottis) which have distinct codes.
• Ensure the documentation specifies "cartilage" as the primary site, not just "larynx, unspecified."
• Sequence this code as the primary diagnosis when it is the reason for the encounter, followed by any associated symptoms or complications.
