ICD-10 Code D23.122 – Other benign neoplasm of skin of left lower eyelid, including canthus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D23.122 – Other benign neoplasm of skin of left lower eyelid, including canthus
What it is
This code identifies a benign skin growth on the left lower eyelid, including the canthus. It indicates a noncancerous lesion recorded by location, not a specific histologic type.
Clinical signs
Clinical features vary; refer to documentation. You may see a visible eyelid lump, localized thickening, or a stable raised lesion on the left lower lid or canthal skin.
When to use this code
Use this code when the provider documents a benign neoplasm of the skin on the left lower eyelid, including the canthus, and no more specific pathology is named. It is appropriate for confirmed benign lesions, such as when the chart clearly identifies the site and benign nature. If the note only says “eyelid lesion,” check documentation.
Do not use for
Do not use this code for malignant eyelid tumors, uncertain masses, or inflammatory eyelid conditions. If the diagnosis is a cyst, wart, or other non-neoplastic lesion, choose the documented condition instead.
Coding tip
Verify both the benign nature and the exact left lower eyelid location before assigning D23.122.
