Squamous cell carcinoma skin/ r upper eyelid, inc canthus

This code signifies a malignant neoplasm originating from squamous cells, specifically located on the skin of the right upper eyelid, encompassing the canthal region. It indicates a primary cancerous growth in this precise anatomical location.

Apply this code for documented cases of squamous cell carcinoma affecting the skin of the patient's right upper eyelid, including any involvement of the inner or outer canthus. Documentation should clearly specify the histology (squamous cell carcinoma) and the exact anatomical site.

• Ensure laterality (right) and specific eyelid involvement (upper) are clearly documented.
• Distinguish from basal cell carcinoma or melanoma of the eyelid, which have different codes.
• Confirm the diagnosis is primary squamous cell carcinoma, not a metastatic lesion.
