Malignant neoplasm of anterior two-thirds of tongue, part unspecified

This code signifies a cancerous tumor located in the front two-thirds of the tongue, where the specific sub-location within that region is not documented. This includes the tip, dorsum, and lateral borders of the tongue, excluding the base. It represents a primary malignancy originating in this area.

Apply this code when documentation clearly indicates a malignant neoplasm of the anterior two-thirds of the tongue, but the precise part (e.g., tip, lateral border) is not specified. This code is appropriate when the physician's notes confirm a diagnosis of tongue cancer limited to the anterior portion without further anatomical detail.

• Ensure the documentation specifies "malignant" and "anterior two-thirds" of the tongue.
• If a more specific location within the anterior two-thirds is documented (e.g., tip of tongue), use a more precise code.
• This code should not be used for malignancies of the base of the tongue or unspecified parts of the tongue where the anterior two-thirds is not explicitly stated.
