Malignant neoplasm of glottis

This code signifies a primary cancerous tumor originating in the glottis, which is the part of the larynx containing the vocal cords. This malignancy can affect vocal cord function, leading to hoarseness or other voice changes. It represents a serious condition requiring definitive diagnosis and treatment.

Use this code for documented cases of primary malignant neoplasm specifically located within the glottis. This diagnosis is typically confirmed by biopsy and pathology reports. Documentation should clearly specify the glottis as the primary site of the malignancy.

• Ensure documentation specifies "glottis" and not a more general laryngeal site.
• Distinguish from benign glottic lesions or secondary/metastatic tumors to the glottis.
• Sequence as the primary diagnosis when the glottic malignancy is the reason for the encounter.
