Yes. What you pay for drugs may vary, depending upon how the plan sets up its network. Plans can have preferred and non-preferred network pharmacies, and can charge more for drugs purchased at the non-preferred locations. They may also charge less if you use a mail order pharmacy.
The pricing difference will be very limited if you are receiving a low-income subsidy. For the remainder of 2020 you will pay no more than $8.95 for your brand-name drugs ($3.60 for generics) if you go to a pharmacy that is in the plan’s network. In 2021, costs are no more than $9.20 for each brand-name and $3.70 for each generic covered drug.
