Malignant neoplasm of parotid gland

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

Use this code when documentation confirms a primary malignant neoplasm of the parotid gland. This diagnosis is typically established through biopsy and histopathological examination. Supporting documentation will include pathology reports, physician notes detailing the diagnosis, and imaging studies confirming the tumor's location.

• Always confirm the primary site of the malignancy; do not use for metastatic disease to the parotid.
• Specificity regarding the histological type (e.g., mucoepidermoid carcinoma) should be captured with additional codes if available.
• Ensure documentation clearly distinguishes between benign and malignant parotid gland tumors.
