Squamous cell carcinoma of skin of unspecified parts of face

This code identifies a malignant neoplasm originating from the squamous cells of the epidermis, specifically located on the face, where the precise facial subsite is not documented. Squamous cell carcinoma (SCC) is a common type of non-melanoma skin cancer, characterized by abnormal, uncontrolled growth of squamous cells.

Apply this code when the medical record clearly states a diagnosis of squamous cell carcinoma affecting the skin of the face, but does not specify a more precise anatomical location (e.g., nose, eyelid, lip). Documentation should confirm the malignant nature of the lesion and its facial involvement without further specificity.

• Avoid using this code if a more specific facial subsite (e.g., C44.321 for skin of eyelid, C44.322 for skin of nose) is documented.
• Ensure the pathology report confirms squamous cell carcinoma.
• Sequence this code as the primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if treated concurrently with another condition.
