Malignant neoplasm of tip and lateral border of tongue

This code signifies a cancerous tumor originating on the anterior-most portion or the side edges of the tongue. This malignancy involves uncontrolled growth of abnormal cells in these specific anatomical regions.

This code is appropriate when documentation confirms a primary malignant neoplasm located on the tip or lateral border of the tongue, often identified through biopsy and imaging. Use this code for initial diagnosis, treatment, and follow-up of such a malignancy.

• Ensure the documentation explicitly states "tip" or "lateral border" of the tongue; avoid using for general tongue malignancies.
• Distinguish from other tongue subsites (e.g., dorsal, ventral, base) which have different codes.
• Confirm laterality if specified in the pathology report, although this code does not differentiate.
