Medicare Part B prescription drugs are not covered under the prescription drug benefit (Part D). Generally, we cover only prescription drugs, vaccines, biological products and medical supplies that are covered under the Medicare prescription drug benefit (Part D) and that are on our formulary.

Express Scripts Medicare's pharmacy network includes limited lower-cost, preferred pharmacies in rural areas in Alaska; the Saver plan also includes limited lower-cost, preferred pharmacies in suburban areas in Puerto Rico, and the Choice plan also includes limited lower-cost, preferred pharmacies in rural areas in Oklahoma. The lower costs advertised in our plan materials for these pharmacies may not be available at the pharmacy you use. For up-to-date information about our network pharmacies, including whether there are any lower-cost preferred pharmacies in your area, please call Customer Service at 1.866.477.5703; TTY: 1.800.716.3231, or consult the online pharmacy directory.

Certain prescription drugs will have maximum quantity limits.

Your prescriber must get prior authorization from Express Scripts Medicare for certain prescription drugs.

Covered Part D drugs are available at out-of-network pharmacies under certain circumstances, including illness while traveling outside the plan's service area, where there is no network pharmacy. You may also incur an additional cost for drugs received at an out-of-network pharmacy.

We have free interpreter services available to answer any questions you may have about the plan. View information on multi-language interpreter services.
