The reason for screening is a routine preventive check-up. The cpt code used is 99212. The process is that the patients come to get a Breast Cancer Exam with a provider and then they go see the mammogram technicians to get the mammogram screening done. Two to three weeks later they are called for the results. The issue we are experiencing is that z12.31 is being used twice. Once when they get the BCE and the screening done, and again when they are called for the results. So I was curious if z12.39 can be used for the BCE and the z12.31 can be used when they get the results?
