ICD-10 Code D10.1 – Benign neoplasm of tongue (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D10.1 – Benign neoplasm of tongue
What it is
D10.1 identifies a noncancerous tumor of the tongue. Use it when documentation states a benign neoplasm arising from tongue tissue.
Clinical signs
Clinical features vary; refer to documentation. Benign tongue lesions may appear as a localized mass, nodule, or growth and are usually described as nonmalignant on exam or pathology.
When to use this code
Use D10.1 when the provider documents a benign neoplasm of the tongue, including a confirmed benign tumor on biopsy or surgical pathology. It also fits when the diagnosis is made clinically and recorded as benign. If the note only says “oral lesion” or “tongue mass,” check documentation for a more specific diagnosis.
Do not use for
Do not use this code for malignant tongue tumors, dysplasia, or unspecified oral lesions. Check documentation if the lesion is inflammatory, traumatic, cystic, or otherwise not described as a benign neoplasm.
Coding tip
Code the most specific tongue site and verify that “benign” is explicitly documented before assigning D10.1.
