ICD-10 Code D22.10 – Melanocytic nevi of unspecified eyelid, including canthus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D22.10 – Melanocytic nevi of unspecified eyelid, including canthus
What it is
This code identifies a benign melanocytic nevus on the eyelid or canthus when the exact eyelid site is not specified. Use it when documentation confirms a mole-like pigmented lesion in this area.
Clinical signs
Findings usually include a well-defined pigmented or skin-colored lesion on the eyelid margin, lid skin, or canthus. Clinical features vary; refer to documentation for laterality, size, and whether the lesion is stable or changing.
When to use this code
Use D22.10 when the provider documents a melanocytic nevus of the eyelid or canthus but does not identify the upper, lower, or unspecified eyelid more precisely. It also fits routine ophthalmic or dermatologic assessment of a benign nevus without evidence of malignancy. If laterality or exact eyelid location is documented, code more specifically when available.
Do not use for
Do not use this code for malignant melanoma, atypical/dysplastic nevi, or non-melanocytic skin lesions. Check documentation if the lesion is described only as a freckle, cyst, or unspecified eyelid mass.
Coding tip
Look for exact anatomic wording in the note; if the eyelid site is unclear, this unspecified code is appropriate.
