ICD-10 Code D23.1 – Other benign neoplasm of skin of eyelid, including canthus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D23.1 – Other benign neoplasm of skin of eyelid, including canthus
What it is
D23.1 identifies a noncancerous growth of the skin on the eyelid or canthus. Use it when documentation states a benign skin neoplasm in this location and no more specific code is given.
Clinical signs
These lesions are usually localized, slow-growing, and well circumscribed. Clinical features vary; refer to documentation for the lesion type, appearance, and whether pathology confirms benign behavior.
When to use this code
Use D23.1 when the record documents a benign skin tumor of the eyelid, including the inner or outer canthus. This code fits cases such as a benign eyelid mass, papule, or nodule when the provider does not specify a more exact histology.
If the note only says “benign lesion” without confirming neoplasm, check documentation before coding. Also use the laterality and site details in the chart to support the eyelid or canthus location.
Do not use for
Do not use this code for malignant eyelid tumors, inflammatory lesions, or cysts unless the provider documents a benign neoplasm. Check documentation when the diagnosis is uncertain or the lesion is not clearly neoplastic.
Coding tip
Code from the provider’s final diagnosis, and verify that “eyelid” or “canthus” is specifically documented before assigning D23.1.
