However, some prescription drug plans do offer a $0 copay for a 90-day supply when purchasing Tier 1 Preferred Generics and Tier 2 Generics at a preferred pharmacy -- even more plans offer the $0 copay if you buy a 90-day supply using their mail-order service.
To see a chart detailing the plan's cost-sharing, you can click the Rx$ button under the plan name on our PDP-Finder.com plan finder.
The Rx Cost-Sharing Details page highlights the plan's 30-day and 90-day supply cost-sharing for all formulary drug tiers across all phases of coverage, and for preferred, standard, and mail order network pharmacies.
Your plan's documentation -- Summary of Benefits and Evidence of Coverage -- will provide more information about coverage. Also, if you are uncertain about your Medicare Part D plan benefits, you can telephone your plan's Member Services department and asking a plan representative for more details. The toll-free telephone number for Member Services is found on your Medicare Part D Member ID card.
Alternatively, the Member Services telephone number for most Medicare Part D plans can be found by clicking on the plan name or Benefits & Contact Info button on our PDP-Finder.com plan finder.
