Which statement is true regarding Prescription Drug Plans (PDPs) and preferred pharmacies?

The statement that all plans feature a $0 Tier 1 benefit at preferred pharmacies accurately reflects the common structure of many Prescription Drug Plans (PDPs). Typically, Tier 1 medications are generics, which are priced lower than brand-name drugs. Preferred pharmacies often negotiate more favorable pricing for these generic drugs, allowing PDPs to offer a $0 copayment for members when they utilize these pharmacies. This approach is designed to encourage the use of lower-cost medications, thus providing a financial benefit to both the member and the plan.

The other statements do not accurately capture the typical features of PDPs. Not all Tier 1 benefits are exclusive to generic pharmacies, they are generally more widely available at preferred pharmacies. Furthermore, it is inaccurate to suggest that PDPs completely lack Tier 1 benefits, as most do provide these as part of their formulary. Finally, the assertion that only certain PDPs have a discounted Tier 1 benefit is misleading, as many plans offer standard Tier 1 pricing at preferred pharmacies across the board.
