Benign neoplasm of other parts of mouth

This code represents a non-cancerous growth originating from various unspecified locations within the oral cavity, excluding the lips, soft palate (nasopharyngeal surface), and odontogenic structures. These benign tumors are typically slow-growing and do not metastasize.

Use this code when documentation specifies a benign neoplasm of the mouth, but the precise subsite is not further specified or falls outside of the more specific D10.0 or D10.6 categories. This code is appropriate for benign lesions of the buccal mucosa, floor of mouth, or hard palate when a more specific code is unavailable.

• Ensure the documentation explicitly states "benign neoplasm" and specifies a location within the mouth that is not the lip, nasopharyngeal surface of the soft palate, or odontogenic.
• Review the "Excludes1" notes carefully to avoid incorrect co-coding with benign odontogenic neoplasms (D16.4-D16.5) or benign neoplasms of the lip (D10.0) or nasopharyngeal surface of the soft palate (D10.6).
• If the specific location within the mouth is known and has a more precise code (e.g., D10.30 for unspecified part of mouth, D10.31 for tongue), use that more specific code instead.
