Sebaceous cell carcinoma skin/ r upper eyelid, inc canthus

This code identifies a malignant tumor originating from the sebaceous glands of the skin, specifically located on the right upper eyelid, including the canthus. Sebaceous cell carcinoma is an aggressive form of skin cancer that can mimic other benign eyelid conditions.

Apply this code when documentation clearly specifies a confirmed diagnosis of sebaceous cell carcinoma affecting the skin of the right upper eyelid, encompassing the canthal region. This diagnosis is typically established through biopsy and histopathological examination.

• Ensure laterality (right) and specific eyelid involvement (upper) are explicitly documented.
• Verify the histological confirmation of sebaceous cell carcinoma, differentiating it from other eyelid malignancies like basal cell or squamous cell carcinoma.
• Code any associated complications or metastatic sites separately.
