Unsp malignant neoplasm skin/ unsp upper limb, inc shoulder

This code signifies a cancerous growth originating in the skin tissue of an unspecified upper extremity, encompassing the shoulder region. The specific type of skin cancer (e.g., basal cell carcinoma, squamous cell carcinoma, melanoma) is not documented or determined.

This code is appropriate when a malignant skin neoplasm is identified on any part of the upper limb, including the shoulder, but the laterality (left or right) is not specified in the medical record. It is also used when the specific histological type of the skin cancer has not yet been confirmed or documented.

• Avoid using this code if the laterality of the upper limb is known; instead, use a more specific code for the left (C44.61-) or right (C44.62-) upper limb.
• Do not use this code if the specific type of skin cancer (e.g., basal cell, squamous cell, melanoma) is documented; instead, select the appropriate histology-specific code.
• This code should be considered a temporary or placeholder code if further diagnostic information is expected to specify laterality or histology.
