To find out what you are entitled to, call your insurance company (before you have your lab work, test, mammogram, procedure, etc., done) and ask what your benefits for screening are. Tell your insurance company exactly what your doctor has ordered for you and also give them all of the diagnoses that your doctor has put on your order. Your order may contain both screening and diagnostic tests with screening and diagnostic diagnoses on it, depending on what you saw your doctor for, and it is important to know which test corresponds with which diagnosis.
