Malignant melanoma of right upper limb, including shoulder

This code signifies a primary malignant melanoma originating in the skin of the right upper extremity, encompassing the shoulder region. This aggressive form of skin cancer arises from melanocytes and can metastasize if not detected and treated early.

Apply this code when documentation confirms a diagnosis of malignant melanoma located anywhere on the patient's right arm, including the shoulder, elbow, forearm, wrist, or hand. Supporting documentation should clearly specify the primary nature of the tumor and its anatomical location within the right upper limb.

• Ensure the documentation explicitly states "malignant melanoma" and specifies the "right upper limb" or a specific site within it.
• Distinguish from benign melanocytic nevi (D22.-) or melanoma in situ (D03.-), which are coded differently.
• Properly sequence with codes for any subsequent treatment, such as surgical excision (e.g., CPT codes for excisions) or chemotherapy.
