Personal history of malignant neoplasm of breast

This code indicates that a patient has a documented history of a malignant tumor originating in the breast, but the malignancy is no longer active or present. It signifies that the patient has completed treatment for breast cancer and is currently considered cancer-free or in remission.

This code is appropriate for patients who have a past diagnosis of breast cancer and are now presenting for follow-up care, screening, or treatment of unrelated conditions. It is also used when a patient's past medical history of breast cancer is relevant to current medical decision-making, such as medication choices or risk assessments.

• Only use this code when the breast malignancy is no longer active and has been successfully treated.
• Do not use this code if the patient has active breast cancer; instead, use the appropriate codes from the 174 series.
• Always review the patient's medical record to confirm the status of the breast cancer (active vs. history).
