Unsp malignant neoplasm skin/ unsp lower limb, including hip

This code signifies a cancerous growth originating in the skin of a lower limb, including the hip, where the specific type of malignancy (e.g., melanoma, basal cell carcinoma) has not been determined. It indicates that the primary site of the tumor is the skin of the lower extremity, but further pathological or clinical details are lacking.

Use this code when documentation confirms a malignant skin neoplasm on a lower limb or hip, but the specific histological type of cancer is not specified by the provider. This code is appropriate when the laterality (left or right) of the affected limb is also not documented.

• Avoid using this code if a more specific histological type of skin cancer (e.g., melanoma, squamous cell carcinoma) is documented.
• Do not use if the laterality of the lower limb is specified; instead, choose a more precise code indicating left or right.
• Query the provider for more specific information regarding the type of malignancy and laterality if available, to allow for more precise coding.
