Oth malignant neoplasm skin/ left lower limb, including hip

This code signifies a malignant skin tumor that is not a melanoma, basal cell carcinoma, or squamous cell carcinoma, located on the left lower extremity, including the hip. It encompasses various less common skin cancers, such as Merkel cell carcinoma, dermatofibrosarcoma protuberans, or atypical fibroxanthoma, when they arise in this specific anatomical region.

Apply this code when documentation clearly identifies a primary malignant neoplasm of the skin on the left lower limb or hip, and the pathology report specifies a type of skin cancer other than melanoma, basal cell, or squamous cell carcinoma. This code is appropriate for initial diagnosis, treatment, and follow-up care of such conditions.

• Ensure the pathology report explicitly states "other specified malignant neoplasm" or provides a specific diagnosis that falls under this category.
• Verify laterality (left) and anatomical site (lower limb, including hip) are clearly documented.
• Do not use for melanoma, basal cell carcinoma, or squamous cell carcinoma; specific codes exist for these common types.
