Squamous cell carcinoma of skin of nose

This code identifies a malignant neoplasm originating from the squamous cells of the epidermis, specifically located on the skin of the nose. This is a common type of skin cancer, often characterized by scaly red patches, open sores, elevated growths with a central depression, or wart-like lesions.

Apply this code when documentation clearly indicates a confirmed diagnosis of squamous cell carcinoma affecting the external skin of the nose. This diagnosis is typically established through biopsy and histopathological examination. Use this code for primary diagnoses, or as a secondary diagnosis when managing complications or treatment of the carcinoma.

• Ensure documentation specifies "squamous cell carcinoma" and not other types of skin cancer (e.g., basal cell).
• Verify the anatomical site is explicitly "skin of nose" to differentiate from other facial or head and neck sites.
• Do not use for carcinoma in situ; a separate code exists for that specific stage.
