Personal history of malignant neoplasm of breast

This code indicates that a patient has a past medical history of breast cancer that has been successfully treated and is currently in remission. It signifies that the patient no longer has active malignancy but requires ongoing surveillance due to their prior diagnosis. This history is a crucial factor in future medical management and risk assessment.

Use this code for patients who have completed definitive treatment for breast cancer and are now considered cancer-free. This applies during follow-up appointments, screenings, or for any medical encounter where the patient's prior breast cancer history is relevant to their current care. It should be assigned when there is no evidence of current disease.

• Always sequence this code after any codes for current signs, symptoms, or conditions being treated.
• Do not use this code if the patient has active breast cancer; instead, use the appropriate C-series code.
• Ensure documentation clearly states the patient's history of breast cancer and current remission status.
