Other specified malignant neoplasm of skin of nose

This code signifies a malignant tumor of the skin on the nose that is not a basal cell carcinoma, squamous cell carcinoma, or melanoma. It encompasses less common or histologically distinct skin cancers affecting the nasal region.

Apply this code when documentation specifies a malignant neoplasm of the nasal skin that is identified as "other specified" or a type not covered by more specific codes (e.g., Merkel cell carcinoma, sebaceous carcinoma). Ensure the pathology report confirms the malignancy and its location on the nose.

• Always review the pathology report for the definitive diagnosis and specific cell type.
• Do not use this code for basal cell carcinoma (C44.31x), squamous cell carcinoma (C44.32x), or melanoma (C43.3) of the nose.
• Confirm the exact subsite on the nose if further specificity is available (e.g., ala, bridge).
