ICD-10 Code D23.0 – Other benign neoplasm of skin of lip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D23.0 – Other benign neoplasm of skin of lip
What it is
D23.0 identifies a benign, noncancerous skin growth on the lip. Use it for lesions arising from the skin of the lip, not for malignant, premalignant, or mucosal conditions.
Clinical signs
These lesions are usually localized, well-defined, and slow growing. Clinical features vary; refer to documentation for appearance, size, color, and whether the lesion is symptomatic or incidental.
When to use this code
Use D23.0 when the provider documents a benign neoplasm of the lip skin, such as a diagnosed benign mass or lesion. It also fits when pathology or clinical assessment confirms a nonmalignant skin tumor on the lip. If the record only says “lip lesion,” check documentation for the exact diagnosis.
Do not use for
Do not use this code for malignant lip tumors, dysplastic or premalignant lesions, or benign conditions of the oral mucosa. Check documentation if the lesion is on the vermilion border versus inside the mouth.
Coding tip
Verify the provider’s exact anatomic site and pathology wording before assigning D23.0.
