ICD-10 Code D22.1 – Melanocytic nevi of eyelid, including canthus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D22.1 – Melanocytic nevi of eyelid, including canthus
What it is
D22.1 identifies a benign melanocytic nevus on the eyelid or at the canthus. Use it when documentation describes a mole or nevus in this periocular location.
Clinical signs
These lesions are usually well-circumscribed, pigmented, and stable in appearance. Clinical features vary; refer to documentation if the note does not clearly describe a benign nevus.
When to use this code
Use D22.1 when the provider documents a melanocytic nevus of the eyelid, including the inner or outer canthus. It also fits when the lesion is excised or evaluated and the diagnosis remains a benign nevus. If the site is only “eyelid” without more detail, this code still applies.
Do not use for
Do not use this code for malignant melanoma, dysplastic nevus, or nonspecific eyelid lesions without a documented melanocytic nevus. Check documentation when the diagnosis is uncertain.
Coding tip
Verify the exact eyelid location and that the lesion is documented as benign before assigning D22.1.
