ICD-10 Code D22.5 – Melanocytic Nevi of Trunk (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D22.5 – Melanocytic nevi of trunk
What it is
D22.5 identifies a benign melanocytic nevus located on the trunk, including the chest, abdomen, and back. It is used when documentation specifies a mole or nevus in that anatomic area.
Clinical signs
These lesions are usually well-defined pigmented spots or papules and may be flat or raised. Clinical features vary; refer to documentation, especially if the note describes change in color, size, or shape.
When to use this code
Use this code when the provider documents a melanocytic nevus on the trunk and no more specific site code is given. It also fits routine evaluation of a benign mole on the chest, abdomen, or back. If the record only says “nevus,” check documentation for the exact type and location.
Do not use for
Do not use D22.5 for atypical, dysplastic, or malignant pigmented lesions. Also avoid it when the nevus is documented on another body site, since location drives code selection.
Coding tip
Confirm both the lesion type and the anatomic site in the note before assigning D22.5.
