Sebaceous cell carcinoma skin/ right low eyelid, inc canthus

This code identifies a malignant neoplasm originating from the sebaceous glands of the skin, specifically located on the right lower eyelid, encompassing the canthus region. This aggressive form of skin cancer can mimic benign eyelid conditions, making accurate diagnosis crucial.

Apply this code when documentation confirms a biopsy-proven sebaceous cell carcinoma affecting the skin of the patient's right lower eyelid, including any involvement of the inner or outer canthus. This diagnosis is typically made following an excisional biopsy or Mohs surgery.

• Ensure laterality (right) and specific eyelid involvement (lower) are clearly documented.
• Distinguish from other eyelid malignancies like basal cell or squamous cell carcinoma.
• Confirm the "sebaceous cell" histology; do not use for unspecified eyelid skin cancers.
