Squamous cell carcinoma skin/ right upper limb, inc shoulder

This code identifies a malignant neoplasm originating from the squamous cells of the epidermis, specifically located on the right upper extremity, which includes the shoulder region. This is a common type of non-melanoma skin cancer that can be locally invasive and has the potential for metastasis.

Apply this code when documentation confirms a biopsy-proven squamous cell carcinoma affecting any part of the right arm or shoulder. This includes primary tumors, as well as recurrent or metastatic lesions where the primary site was the right upper limb. Documentation should clearly specify the laterality and histological type.

• Ensure the documentation explicitly states "squamous cell carcinoma" and specifies the right upper limb or shoulder.
• Do not use this code for basal cell carcinoma or melanoma; these have distinct codes.
• Confirm laterality; separate codes exist for the left upper limb and unspecified laterality.
