  • Z12.31: Encounter for screening mammogram for malignant neoplasm of the breast - This code is used when the primary reason for the mammogram is routine screening for breast cancer.
  • Z85.3: Personal history of malignant neoplasm of the breast - Indicates that a patient has had breast cancer in the past, and this history can be a reason for ongoing monitoring with mammograms.
  • Z80.3: Family history of malignant neoplasm of the breast - Indicates a family history of breast cancer, a potential risk factor leading to more frequent or earlier screenings.
