Network pharmacies
Pharmacies that have agreed to provide members of certain Medicare plans with services and supplies at a discounted price. In some Medicare plans, your prescriptions are only covered if you get them filled at network pharmacies.
Non-preferred pharmacy
A pharmacy that's part of a Medicare drug plan's network, but isn't a preferred pharmacy. You may pay higher out-of-pocket costs if you get your prescription drugs from a non-preferred pharmacy instead of a preferred pharmacy.
