Squamous cell carcinoma skin/ unsp eyelid, including canthus

This code signifies a malignant neoplasm originating from the squamous cells of the epidermis, specifically located on an unspecified eyelid or the canthus (corner of the eye). It represents a common type of non-melanoma skin cancer affecting the delicate periorbital region.

Use this code when documentation confirms a diagnosis of squamous cell carcinoma affecting the eyelid, without specifying which eyelid (right or left), or if the lesion is explicitly located at the canthus. This diagnosis is typically made via biopsy and histopathological examination.

• Ensure the documentation specifies "squamous cell carcinoma" and not another type of skin cancer (e.g., basal cell carcinoma).
• If the specific eyelid (right or left) is documented, a more specific code from the C44.12- series should be used.
• Confirm the lesion is on the skin of the eyelid/canthus, not an intraocular or adnexal structure.
