Personal history of other malignant neoplasm of skin

This code indicates a patient's past history of a malignant skin neoplasm that is not melanoma, basal cell carcinoma, or squamous cell carcinoma. This includes rare or less common types of skin cancer that have been successfully treated and are no longer present.

Use this code when documenting a patient's history of a previously excised or treated malignant skin tumor other than melanoma, basal cell, or squamous cell carcinoma. This is appropriate for follow-up visits or when the history is relevant to current care, and there is no evidence of recurrence or active disease.

• Assign this code as a secondary diagnosis when the patient is seen for a condition other than the skin cancer itself.
• Ensure the medical record clearly specifies the type of skin cancer if it falls outside of melanoma, basal cell, or squamous cell.
• Do not use this code if the patient has an active or recurrent malignant neoplasm; instead, code the active malignancy.
