Malignant neoplasm of submandibular gland

This code signifies a primary cancerous tumor originating in the submandibular gland, one of the major salivary glands located beneath the floor of the mouth. This malignancy can involve various histological types, such as mucoepidermoid carcinoma or adenoid cystic carcinoma, and is characterized by uncontrolled cell growth within the gland tissue.

Apply this code when documentation clearly indicates a primary malignant neoplasm confirmed to be located in the submandibular gland. This typically follows a biopsy and pathological confirmation, or imaging studies highly suggestive of malignancy in this specific anatomical site. Use for initial diagnosis, active treatment, or surveillance of this specific cancer.

• Ensure the documentation specifies "submandibular gland" and not another salivary gland (e.g., parotid, sublingual).
• Confirm the neoplasm is primary and malignant; do not use for benign tumors or secondary metastases to this site.
• Always review pathology reports for definitive diagnosis and laterality if specified, though C08.0 does not differentiate laterality.
