Sebaceous cell carcinoma skin/ left low eyelid, inc canthus

This code identifies a malignant neoplasm originating from sebaceous glands, specifically located on the skin of the left lower eyelid, encompassing the canthus. This aggressive form of skin cancer can mimic benign eyelid conditions but is characterized by uncontrolled growth of abnormal sebaceous cells.

Use this code when documentation clearly states a confirmed diagnosis of sebaceous cell carcinoma affecting the skin of the patient's left lower eyelid, including any involvement of the canthus. This diagnosis is typically established through biopsy and histopathological examination.

• Ensure laterality is explicitly documented as "left" and the specific eyelid (lower) is identified.
• Distinguish from basal cell carcinoma or squamous cell carcinoma of the eyelid, which have different ICD-10-CM codes.
• Verify that the documentation specifies "skin of" the eyelid, as sebaceous carcinoma can also arise from the conjunctiva or meibomian glands.
