Malignant neoplasm of other major salivary glands

This code signifies the presence of a cancerous tumor originating in any of the major salivary glands other than the parotid, submandibular, or sublingual glands. This includes less common major salivary gland sites such as ectopic salivary gland tissue or accessory salivary glands. The malignancy can be of various histological types, such as mucoepidermoid carcinoma or adenoid cystic carcinoma.

Apply this code when documentation specifies a primary malignant neoplasm of a major salivary gland that is not explicitly identified as parotid, submandibular, or sublingual. This is appropriate for pathology reports confirming malignancy in an unspecified major salivary gland or a major salivary gland in an unusual location. Supporting documentation must clearly indicate the malignant nature and the specific major salivary gland involved, excluding the three most common ones.

• Ensure the documentation specifies "major" salivary gland. If "minor" salivary glands are involved, a different code from the 140-149 series (malignant neoplasm of other and unspecified sites within the lip, oral cavity, and pharynx) may be more appropriate.
• Always confirm the primary site. If the salivary gland involvement is metastatic, a secondary malignancy code should be used in conjunction with the primary site.
• Distinguish from benign neoplasms of salivary glands, which are coded to the 210.2 category.
