ICD-10 Code D22.0 – Melanocytic nevi of lip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D22.0 – Melanocytic nevi of lip
What it is
This code identifies a benign melanocytic nevus located on the lip. It is used for a mole or similar pigmented skin lesion arising from melanocytes in that specific site.
Clinical signs
Typical findings include a localized, well-defined pigmented papule or macule on the lip. Clinical features vary; refer to documentation if the lesion changes, is raised, or has atypical color.
When to use this code
Use D22.0 when the provider documents a benign melanocytic nevus of the lip, including a congenital or acquired mole at that location. Apply it when the lesion is identified clinically or removed and pathology confirms a nevus. If the note only says “pigmented lip lesion,” check documentation before coding.
Do not use for
Do not use this code for malignant melanoma, dysplastic nevus, or other non-melanocytic lip lesions. Check documentation if the diagnosis is uncertain or if the lesion is described only as a suspicious mass.
Coding tip
Code the exact anatomic site documented; if the lip location is not specified, query the provider.
