Sebaceous cell carcinoma skin/ unsplid, including canthus

This code signifies a malignant neoplasm originating from sebaceous glands, specifically located on an unspecified eyelid or the canthus. It represents a rare but aggressive form of skin cancer that can mimic benign lesions.

Apply this code when documentation confirms a diagnosis of sebaceous cell carcinoma affecting any part of the eyelid (upper or lower) or the inner/outer canthus, and the specific eyelid is not documented. This diagnosis is typically made via biopsy and histopathological examination.

• Ensure the pathology report explicitly states "sebaceous cell carcinoma" and specifies an eyelid or canthus location.
• If the specific eyelid (e.g., upper, lower) is documented, a more precise code from the C44.11- or C44.12- series should be used.
• Do not confuse with basal cell or squamous cell carcinomas of the eyelid, which have distinct codes.
