ICD-10 Code D22.111 – Melanocytic nevi of right upper eyelid, including canthus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D22.111 – Melanocytic nevi of right upper eyelid, including canthus
What it is
This code identifies a benign melanocytic nevus located on the right upper eyelid, including the canthus. Use it when documentation specifies the lesion is on that exact eyelid area.
Clinical signs
Typical findings include a localized pigmented or flesh-colored nevus on the eyelid margin or adjacent skin. Clinical features vary; refer to documentation for size, color, and whether the lesion is stable or changing.
When to use this code
Use D22.111 when the provider documents a melanocytic nevus of the right upper eyelid, including the canthus, and no malignant or uncertain diagnosis is stated. It may be supported by exam findings, dermatology notes, or ophthalmology documentation. If the note only says “eyelid nevus” without laterality, check documentation.
Do not use for
Do not use this code for malignant melanoma, atypical nevus with different documented behavior, or pigmented lesions not identified as melanocytic nevi. Check documentation if the site is the lower eyelid, left side, or unspecified eyelid.
Coding tip
Confirm laterality and exact eyelid location in the record before assigning D22.111.
