ICD-10 Code D10 – Benign neoplasm of mouth and pharynx (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D10 – Benign neoplasm of mouth and pharynx
What it is
D10 identifies a noncancerous growth in the mouth or pharynx. It covers benign neoplasms in these sites, including lesions that may be localized and slow growing.
Clinical signs
Clinical features vary; refer to documentation. These lesions may appear as a visible mass, swelling, or mucosal lump, and may be found during oral or throat examination.
When to use this code
Use D10 when the provider documents a benign neoplasm of the mouth or pharynx without a more specific site code. It also fits when pathology or clinical assessment confirms a benign tumor in these areas. If the record names a precise subsite, code that specific diagnosis instead.
Do not use for
Do not use D10 for malignant neoplasms, dysplasia, or inflammatory lesions. If the documentation describes a cyst, abscess, or unspecified oral lesion, check documentation.
Coding tip
Capture the exact anatomic site and pathology wording, because the broader D10 code should only be used when no more specific site is documented.
