Squamous cell carcinoma skin/ left upper eyelid, inc canthus

This code identifies a malignant neoplasm originating from the squamous cells of the epidermis, specifically located on the left upper eyelid, encompassing the canthal region. This aggressive form of skin cancer is characterized by uncontrolled growth of abnormal squamous cells.

Apply this code when documentation confirms a diagnosis of squamous cell carcinoma affecting the left upper eyelid, including any involvement of the inner or outer canthus. This is typically supported by pathology reports confirming squamous cell carcinoma and physician notes specifying the exact location and laterality.

• Ensure laterality is accurately documented as "left" and the specific eyelid (upper) is identified.
• Verify that the documentation explicitly states "squamous cell carcinoma" and not another type of skin cancer.
• Confirm the involvement of the canthus, if applicable, as this is specified in the code description.
