ICD-10 Code D22.4 – Melanocytic nevi of scalp and neck (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D22.4 – Melanocytic nevi of scalp and neck
What it is
D22.4 identifies a benign melanocytic nevus located on the scalp or neck. Use it for a mole or similar pigmented skin lesion documented in these anatomic sites.
Clinical signs
These lesions are usually well-circumscribed, pigmented, and stable over time. Clinical features vary; refer to documentation if the appearance, size, or change pattern is not clearly described.
When to use this code
Use D22.4 when the provider documents a melanocytic nevus specifically on the scalp or neck. It is appropriate for routine skin exams, incidental findings, or removal requests when the diagnosis is a benign nevus. Check documentation if the site is broader than scalp or neck.
Do not use for
Do not use this code for malignant melanoma, atypical nevi, or other non-melanocytic skin lesions. If the chart does not clearly identify a nevus on the scalp or neck, check documentation.
Coding tip
Code the exact documented site; if the lesion is on another body area, select the matching D22 category instead.
