Malignant neoplasm of ventral surface of tongue

This code signifies a cancerous growth located on the underside or front portion of the tongue. It specifically refers to a primary malignant tumor originating in the tissues of the ventral surface of the tongue.

This code is appropriate for documenting a confirmed diagnosis of squamous cell carcinoma or other primary malignant neoplasms affecting the ventral aspect of the tongue. Documentation should clearly specify the anatomical site as the ventral surface, often supported by pathology reports.

• Differentiate from malignant neoplasms of other tongue sites (e.g., tip, dorsal surface, unspecified part) using specific anatomical documentation.
• Ensure the pathology report confirms malignancy and the precise location within the tongue.
• Consider sequencing rules for primary versus secondary malignancies if applicable.
