ICD-10 Code D22.122 – Melanocytic nevi of left lower eyelid, including canthus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D22.122 – Melanocytic nevi of left lower eyelid, including canthus
What it is
This code identifies a benign melanocytic nevus located on the left lower eyelid, including the canthus. Use it for a documented mole or nevus in that exact anatomic site.
Clinical signs
Findings typically include a stable, pigmented or skin-colored lesion on the eyelid margin or canthal area. Clinical features vary; refer to documentation.
When to use this code
Use D22.122 when the provider documents a melanocytic nevus specifically on the left lower eyelid or its canthus. It is appropriate for office, ophthalmology, or dermatology notes that clearly identify the site and benign nature of the lesion.
If the note only says “nevus of eyelid” without laterality or exact location, check documentation before coding. Use the most specific code supported by the record.
Do not use for
Do not use this code for malignant melanoma, atypical lesions, or unspecified eyelid nevi. Check documentation if the lesion is on a different eyelid or if the diagnosis is not clearly melanocytic.
Coding tip
Verify laterality and eyelid subsite in the exam note before assigning D22.122.
