Malignant neoplasm of parotid gland

This code signifies the presence of a cancerous tumor originating in the parotid gland, the largest of the major salivary glands located in front of and below the ear. This malignancy can be of various histological types, such as mucoepidermoid carcinoma, adenoid cystic carcinoma, or adenocarcinoma.

Apply this code when documentation confirms a primary malignant neoplasm of the parotid gland, typically following biopsy and pathological confirmation. This is appropriate for initial diagnosis, treatment planning, and follow-up care for this specific cancer.

• Ensure documentation clearly specifies "malignant" to differentiate from benign parotid tumors.
• Do not use for secondary or metastatic lesions to the parotid gland; use appropriate secondary malignancy codes.
• Consider additional codes for specific histological types if documented and if more granular coding is required by payer or facility policy.
