Squamous cell carcinoma skin/ left lower eyelid, inc canthus

This code signifies a malignant neoplasm originating from the squamous cells of the epidermis, specifically located on the left lower eyelid, encompassing the inner or outer corner of the eye (canthus). This is a common type of skin cancer often associated with sun exposure.

Apply this code when documentation confirms a diagnosis of squamous cell carcinoma affecting the skin of the left lower eyelid, including any involvement of the canthus. This diagnosis is typically made via biopsy and histopathological examination.

• Ensure laterality (left) and specific eyelid involvement (lower) are clearly documented.
• Distinguish from basal cell carcinoma (C44.11-) or melanoma (C43.1-) of the eyelid.
• Confirm the histological type is explicitly stated as "squamous cell carcinoma" to avoid miscoding.
