Neoplasm of uncertain behavior of sites of the oral cavity

This code signifies a tumor within the oral cavity that exhibits an indeterminate biological potential, meaning it's neither definitively benign nor malignant. It applies to growths in specific, non-tongue, non-lip, non-salivary gland, and non-pharyngeal sites of the mouth where the pathology report indicates "uncertain behavior."

Utilize this code when a biopsy or surgical pathology report identifies a neoplasm of uncertain behavior located in areas such as the buccal mucosa, floor of mouth, hard palate, or gingiva, and a more specific site code is not available. Documentation must clearly state the neoplasm's uncertain behavior and its precise oral cavity location.

• Do not use this code if the pathology report definitively states benign or malignant behavior; instead, select the appropriate benign or malignant neoplasm code.
• Ensure the documentation specifies an "other specified site" within the oral cavity; avoid using this code for unspecified oral cavity sites (D37.00).
• Always review the complete pathology report to confirm the tumor's behavior and exact anatomical location before assigning this code.
