Basal cell carcinoma skin/ left 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 left upper limb, which encompasses the shoulder region. Basal cell carcinoma (BCC) is the most common type of skin cancer, characterized by slow growth and rare metastasis.

Use this code when documentation clearly indicates a confirmed diagnosis of basal cell carcinoma affecting any part of the left arm or shoulder. This diagnosis is typically established through a biopsy and subsequent histopathological examination. The physician's notes should specify the laterality (left) and the anatomical site (upper limb/shoulder).

• Ensure the documentation explicitly states "basal cell carcinoma" and not another type of skin cancer.
• Verify the laterality is "left" and the anatomical site is "upper limb, including shoulder."
• Do not use this code for squamous cell carcinoma or melanoma; separate codes exist for those diagnoses.
