ICD-10 Code C44.1391 – Sebaceous cell carcinoma of skin of left upper eyelid, including canthus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.1391 – Sebaceous cell carcinoma of skin of left upper eyelid, including canthus
What it is
This code identifies a malignant sebaceous gland tumor arising in the skin of the left upper eyelid, including the canthal area. Use it when documentation specifies sebaceous cell carcinoma at that exact site.
Clinical signs
Clinical features vary; refer to documentation. Eyelid lesions may appear as a firm, painless nodule or a persistent, recurrent eyelid mass that does not resolve with routine care.
When to use this code
Use this code when the provider documents sebaceous cell carcinoma of the left upper eyelid, including the canthus, and the lesion is confirmed as skin-based. It may appear in pathology, operative, or ophthalmology notes. If the record only says eyelid cancer without laterality or exact site, check documentation.
Do not use for
Do not use it for benign eyelid lesions, non-sebaceous skin cancers, or tumors at a different eyelid site. If the documentation does not confirm the left upper eyelid or canthus, code the stated location instead.
Coding tip
Confirm laterality, eyelid subsite, and histology before coding; these details drive correct code selection.
