Malignant neoplasm of dorsal surface of tongue

This code signifies a cancerous tumor originating on the top surface of the tongue. It specifically refers to a malignant growth affecting the dorsal aspect, which is the upper, visible surface of the tongue. This condition involves uncontrolled cell proliferation with the potential for local invasion and metastasis.

Use this code when documentation clearly indicates a primary malignant neoplasm located on the dorsal surface of the tongue. This diagnosis is typically confirmed by biopsy and pathology reports. It is appropriate for initial diagnosis, treatment, and follow-up care for this specific anatomical site.

• Ensure the documentation specifies "dorsal surface" to differentiate from other tongue sites.
• Confirm the neoplasm is explicitly stated as "malignant" to avoid confusion with benign or uncertain lesions.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, unless a complication or metastasis is being treated.
