ICD-10 Code D22 – Melanocytic nevi (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D22 – Melanocytic nevi
What it is
D22 identifies melanocytic nevi, commonly called moles. Use it for benign pigmented skin lesions made of melanocytes, when the record documents a nevus without signs of malignancy.
Clinical signs
These lesions are usually well-circumscribed, brown or black, and flat or raised. Clinical features vary; refer to documentation if the note describes change in size, color, border, or other atypical findings.
When to use this code
Use D22 when the provider documents a benign melanocytic nevus, such as a common mole or multiple nevi. It also fits when the assessment names a specific nevus type but does not indicate dysplasia or melanoma. Check documentation for site and laterality details when required.
Do not use for
Do not use D22 for malignant melanoma, dysplastic nevus with a different documented diagnosis, or other pigmented lesions that are not melanocytic nevi. Check documentation if the lesion is uncertain or described as suspicious.
Coding tip
Code the documented nevus type and location exactly as stated, and avoid D22 if the provider records concern for malignancy.
