ICD-10 Code C44.102 – Unspecified malignant neoplasm of skin of right eyelid, including canthus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.102 – Unspecified malignant neoplasm of skin of right eyelid, including canthus
What it is
This code identifies a malignant skin tumor on the right eyelid or canthus when the exact histology is not specified. Use it when the record confirms cancer of the eyelid skin but does not name a more specific type.
Clinical signs
Findings may include a persistent eyelid lesion, nonhealing ulcer, crusting, bleeding, or a mass at the lid margin or canthus. Clinical features vary; refer to documentation.
When to use this code
Use C44.102 when the provider documents an unspecified malignant neoplasm involving the skin of the right eyelid, including the canthus. It is appropriate when laterality is right and the site is eyelid skin rather than conjunctiva or other eye structures. If pathology or documentation later identifies a more specific malignancy, code that diagnosis instead.
Do not use for
Do not use this code for benign eyelid lesions, carcinoma in situ, or malignant neoplasms of the conjunctiva or other ocular tissues. Check documentation if the lesion site or laterality is unclear.
Coding tip
Verify both the right-sided location and the skin site before assigning C44.102.
