Basal cell carcinoma skin/ right lower limb, including hip

This code identifies a malignant neoplasm originating from the basal cells of the epidermis, specifically located on the right lower extremity, which encompasses the hip region. Basal cell carcinoma is the most common type of skin cancer, characterized by slow growth and rare metastasis.

Apply this code when documentation confirms a diagnosis of basal cell carcinoma affecting any part of the right lower limb, including the hip. Supporting documentation should include pathology reports confirming the diagnosis and clear anatomical site specification.

• Ensure laterality is explicitly documented as "right" lower limb.
• Distinguish from squamous cell carcinoma (C44.72-) and melanoma (C43.7-).
• Verify the specific subsite within the lower limb if more granular coding is available or required for other purposes.
