ICD-10 Code D22.20 – Melanocytic nevi of unspecified ear and external auricular canal (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D22.20 – Melanocytic nevi of unspecified ear and external auricular canal
What it is
D22.20 identifies a benign melanocytic nevus located on the ear or external auricular canal when the site is not further specified. Use it for a mole or similar pigmented lesion documented in that ear region.
Clinical signs
These lesions are usually small, well-circumscribed, and pigmented, though they may be flesh-colored or darker. Clinical features vary; refer to documentation, especially if the record describes change in size, color, or shape.
When to use this code
Use this code when the provider documents a benign melanocytic nevus on the ear or external auricular canal and does not name a more specific ear subsite. It fits routine office, dermatology, or ENT documentation. If the note only says “ear mole,” verify the exact location before coding.
Do not use for
Do not use D22.20 for malignant melanoma, dysplastic nevus, or other non-nevus pigmented lesions. Check documentation if the lesion is described only as suspicious, inflamed, or removed without a clear benign nevus diagnosis.
Coding tip
Code the most specific documented ear site; if the ear canal or auricle is named separately, confirm whether a different ICD-10 code is needed.
