ICD-10 Code C44.1322 – Sebaceous cell carcinoma of skin of right lower eyelid, including canthus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.1322 – Sebaceous cell carcinoma of skin of right lower eyelid, including canthus
What it is
C44.1322 identifies a malignant sebaceous gland tumor arising in the skin of the right lower eyelid, including the canthus. Use it when the provider documents this specific eyelid location and histology.
Clinical signs
Typical findings may include a persistent eyelid nodule, thickening, or a lesion that resembles a chalazion or blepharitis. Clinical features vary; refer to documentation and pathology when available.
When to use this code
Use this code when the record states sebaceous cell carcinoma, sebaceous gland carcinoma, or equivalent wording for the right lower eyelid with canthus involvement. It is appropriate after biopsy, excision, or specialist assessment confirms the site and diagnosis.
If the note only says “eyelid cancer” or does not specify the right lower eyelid, check documentation before coding. Make sure laterality and exact anatomic site are clearly supported.
Do not use for
Do not use this code for benign eyelid lesions, non-sebaceous skin cancers, or tumors on the left eyelid or unspecified side. Check documentation if the canthus is not involved or not stated.
Coding tip
Verify both laterality and the lower eyelid/canthus location in the pathology or operative note before assigning C44.1322.
