This 38-year-old mother of four children has been treated for nearly 20 years for severe cystic breast disease. The patient has elected to have her breasts removed to relieve the pain. She is also very worried about developing breast cancer because her mother died from breast cancer at age 42 years. She has had numerous breast biopsies, and each time they are benign. She may consider plastic reconstruction later but is not interested in it now. She is in good health. She was taken to surgery, and bilateral simple mastectomies were performed. The pathology report shows severe cystic disease of both breasts. What codes are assigned?
