Abstract: A mobile application for a mail order pharmacy program is disclosed. After enrolling in a mail order pharmacy program and receiving one or more prescriptions through the mail, members may use the mobile application to order prescription refills. Members request a prescription refill by scanning a barcode on a prescription vial for a prior fill. In an example embodiment, the barcode comprises an order number and an inventory number from a prior fill. The barcode comprises data that is used in processing the prescription through an automated mail order pharmacy system and that further facilitates reordering using the mobile application. Once received at the mail order pharmacy, the order number and product number from the barcode are used to locate the previous order for the prescription and to issue another order for the prescription that is processed on the automated dispensing line of the mail order pharmacy system.
