Why might a patient be asked for prescription drug coupons at the time of drop-off?

The correct answer is based on the role of prescription drug coupons in enhancing the efficiency of the pharmacy's workflow. When patients present these coupons at the time of drop-off, it allows the pharmacy staff to process the prescription and the coupon simultaneously without having to interrupt workflow later in the process. This is particularly beneficial as it minimizes delays and enhances the speed at which prescriptions are filled. By handling the coupon at the beginning, it reduces the risk of having to rework claims or deal with billing issues later on, leading to a smoother operational flow.

This practice can also improve patient satisfaction, as they are more likely to receive their medications quickly and without complications related to billing and insurance claims. The effective management of these coupons is thus a key part of maintaining an efficient pharmacy workflow.
