Unsp malignant neoplasm skin/ right lower limb, inc hip

This code signifies an undiagnosed cancerous growth originating in the skin of the right lower extremity, encompassing the hip region. It indicates that the specific type of skin cancer (e.g., melanoma, basal cell carcinoma, squamous cell carcinoma) has not yet been determined or documented.

Use this code when documentation clearly states a malignant skin neoplasm on the right lower limb or hip, but the pathology report or clinical notes do not specify the histological type. This is often an interim code used while awaiting definitive pathology results.

• Avoid using this code if a more specific skin cancer type (e.g., melanoma, basal cell carcinoma) is documented; instead, use the appropriate specific code.
• Always strive for the highest level of specificity. If the anatomical site is known more precisely (e.g., right thigh, right ankle), use a more granular code.
• This code should be replaced with a more specific code once the definitive diagnosis of the malignant neoplasm is established.
