Basal cell carcinoma skin/ right upper limb, inc shoulder

This code signifies a malignant neoplasm originating from the basal cells of the epidermis, specifically located on the skin of the patient's right upper extremity, which includes the shoulder region. It represents 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 arm or shoulder. This includes lesions on the upper arm, forearm, hand, or the shoulder itself. Supporting documentation should clearly state the diagnosis and the precise anatomical location.

• Ensure laterality is explicitly documented as "right" for the upper limb.
• Distinguish from squamous cell carcinoma (C44.62-) and melanoma (C43.6-) of the same site.
• Confirm the lesion is indeed basal cell carcinoma; do not use for benign skin lesions or other malignant types.
