ICD-10 Code D10.39 – Benign neoplasm of other parts of mouth (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D10.39 – Benign neoplasm of other parts of mouth
What it is
D10.39 identifies a noncancerous tumor in other specified parts of the mouth. Use it when the lesion is documented as benign and located in an oral site not named by a more specific code.
Clinical signs
Clinical features vary; refer to documentation. Oral benign neoplasms may present as a localized mass, swelling, or mucosal lump that is usually slow growing and not described as malignant.
When to use this code
Use this code when the provider documents a benign neoplasm in an oral location that does not fall under a more specific mouth code. It may be supported by exam findings, biopsy, or pathology confirming benign behavior. If the site is unclear, check documentation before coding.
Do not use for
Do not use for malignant oral tumors, dysplasia, or unspecified mouth lesions. Also avoid it when the record names a different anatomic site that has its own code.
Coding tip
Match the exact oral site in the note to the most specific available code, and use D10.39 only when no more specific mouth location applies.
