2026 ICD-10-CM Diagnosis Code D10.30 – Benign neoplasm of unspecified part of mouth
What it is
This code identifies a noncancerous growth in the mouth when the exact oral site is not documented. It is used for benign tumors arising in an unspecified part of the oral cavity.
Clinical signs
Findings may include a visible or palpable oral mass, localized swelling, or a lesion noted on dental or oral exam. Clinical features vary; refer to documentation.
When to use this code
Use D10.30 when the provider documents a benign neoplasm of the mouth but does not specify the exact location, such as lip, tongue, gum, or palate. You may also use it when the record confirms a benign oral tumor and the anatomic site remains unclear after review.
Do not use for
Do not use this code for malignant oral tumors, dysplasia, or inflammatory lesions. If the site is known, choose the more specific oral cavity code instead.
Coding tip
Review the note for the precise oral subsite before assigning this unspecified code.
