Malignant neoplasm of sublingual gland

This code represents a primary cancerous tumor originating in the sublingual gland, one of the major salivary glands located under the tongue. This malignancy involves uncontrolled growth of abnormal cells within the glandular tissue.

Use this code when documentation clearly indicates a confirmed diagnosis of primary malignant neoplasm of the sublingual gland. This diagnosis is typically established through biopsy and histopathological examination.

• Ensure the documentation specifies "sublingual gland" and not another salivary gland (e.g., parotid, submandibular).
• Verify that the neoplasm is explicitly stated as "malignant" and "primary" to differentiate from benign or secondary tumors.
• Do not use this code for metastatic disease to the sublingual gland; instead, code the primary site and then the secondary malignant neoplasm.
