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. These malignancies are relatively rare and can present with symptoms such as a mass in the floor of the mouth, pain, or difficulty swallowing. Histologically, they often include mucoepidermoid carcinoma or adenoid cystic carcinoma.

Use this code when documentation clearly identifies a primary malignant neoplasm specifically of the sublingual gland. This diagnosis is typically confirmed by biopsy and histopathological examination. It should be used for initial diagnoses, active treatment, and follow-up care related to this specific cancer.

• Ensure the documentation specifies "sublingual gland" and not a general "major salivary gland" or "minor salivary gland."
• Do not confuse with malignant neoplasms of other salivary glands (e.g., parotid, submandibular) or benign tumors of the sublingual gland.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, followed by any relevant secondary diagnoses or manifestations.
