Squamous cell carcinoma skin/ left upper limb, inc shoulder

This code signifies a malignant neoplasm originating from the squamous cells of the epidermis, specifically located on the left upper extremity, encompassing the shoulder region. This is a common type of skin cancer that can be locally invasive and, if untreated, may metastasize.

Apply this code when documentation clearly states a confirmed diagnosis of squamous cell carcinoma affecting any part of the left arm, including the shoulder. This diagnosis is typically established through biopsy and histopathological examination.

• Ensure the laterality (left) and specific body site (upper limb, including shoulder) are explicitly documented.
• Distinguish from basal cell carcinoma (C44.61-) and melanoma (C43.6-), which are coded differently.
• Do not use for carcinoma in situ; refer to D04.6- for those cases.
