ICD-10 Code D10.2 – Benign neoplasm of floor of mouth (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D10.2 – Benign neoplasm of floor of mouth
What it is
D10.2 identifies a noncancerous growth arising in the floor of the mouth. Use it when the provider documents a benign neoplasm in this oral cavity site.
Clinical signs
Findings may include a localized oral mass, swelling, or a slow-growing lesion in the floor of mouth. Clinical features vary; refer to documentation.
When to use this code
Use D10.2 when the record clearly states a benign neoplasm of the floor of mouth, such as a pathology-confirmed benign tumor or a documented nonmalignant oral lesion at that site. Code it from the provider’s final diagnosis, not from suspicion alone.
Do not use for
Do not use this code for malignant oral tumors, dysplasia, or unspecified oral masses. Check documentation if the lesion site or benign nature is not confirmed.
Coding tip
Verify both the benign nature and the exact anatomic site before assigning D10.2.
