Hi John.
Those numbers relate to our new eCoupon/Co-Pay assistance functionality, and provide details to the pharmacist processing the prescription. The eCoupon/Co-Pay Assistance program can help your patients save money on their prescriptions - at no cost to you. We have worked hard to ensure that including eCoupon/Co-Pay Assistance information will not adversely affect the performance of our ePrescribing module. If you still would prefer to disable this new functionality, You can turn it off by going into your user-preferences (main screen of AC and then hit CTRL + U) and selecting "Prescriptions" and unchecking "Participate in Copay Assistance.
