ICD-10 Code D23.12 – Other benign neoplasm of skin of left eyelid, including canthus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D23.12 – Other benign neoplasm of skin of left eyelid, including canthus
What it is
D23.12 identifies a benign skin growth on the left eyelid or canthus. It means the lesion is noncancerous and located on the skin of that specific eye area.
Clinical signs
Clinical features vary; refer to documentation. These lesions are usually described as a localized, slow-growing eyelid skin mass, nodule, or papule, with benign appearance and no evidence of invasion.
When to use this code
Use D23.12 when the provider documents a benign neoplasm of the skin on the left eyelid, including the inner or outer canthus. Apply it when the site is clearly the left side and the lesion is not described as malignant, uncertain, or unspecified.
If the note only says “eyelid lesion” or does not identify laterality, check documentation before coding. You should also confirm that the lesion is skin-based rather than conjunctival or another ocular structure.
Do not use for
Do not use this code for malignant, in situ, or unspecified eyelid lesions. It is also wrong for lesions of the right eyelid, bilateral eyelids, or non-skin eye disorders.
Coding tip
Verify both laterality and benign behavior in the assessment before assigning D23.12.
