Basal cell carcinoma skin/ unsp lower limb, including hip

This code signifies a malignant neoplasm originating from the basal cells of the epidermis, specifically located on an unspecified lower limb, which includes the hip region. It represents the most common type of skin cancer, characterized by slow growth and rare metastasis.

Use this code for documented cases of basal cell carcinoma affecting any part of the lower limb, including the hip, when the specific anatomical site (e.g., thigh, calf, foot) is not specified in the medical record. This code is appropriate when the pathology report confirms basal cell carcinoma and the physician's documentation indicates the general lower limb or hip area without further precision.

• Ensure the pathology report confirms basal cell carcinoma; do not code based solely on clinical suspicion.
• If a more specific location on the lower limb (e.g., C44.712 for right lower limb, C44.719 for unspecified lower limb) is documented, use that more precise code.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter (e.g., for excision, biopsy, or treatment).
