Benign neoplasm of floor of mouth

This code signifies the presence of a non-cancerous growth originating from the tissues forming the floor of the mouth. These benign neoplasms are typically slow-growing and do not metastasize, but may cause symptoms due to their size or location.

Use this code when diagnostic imaging (e.g., MRI, CT) or biopsy confirms a benign tumor located in the floor of the mouth. Documentation should clearly specify the benign nature of the lesion and its anatomical site within the oral cavity.

• Differentiate carefully between benign and malignant neoplasms; a different code series applies for malignancy.
• Ensure the documentation specifies "floor of mouth" to avoid confusion with other oral cavity sites.
• Do not use this code for inflammatory lesions or cysts; these have distinct ICD-9-CM codes.
