Medicare Advantage (Part C) plans bundle hospital, medical, and usually prescription drug coverage (MA-PD) into a single plan from a private insurer. Each MA plan has its own formulary, which must meet CMS minimum coverage standards.

Frequently Asked Questions

Is drug coverage included in Medicare Advantage plans?

Most Medicare Advantage plans (called MA-PD plans) include Part D prescription drug coverage. However, some MA-only plans do not include drug coverage. If you choose an MA-only plan, you would need a separate standalone Part D plan. Check the plan details before enrolling.

How do Medicare Advantage formularies differ from standalone Part D?

Both must meet CMS minimum coverage requirements. However, MA plans may have different formularies, preferred pharmacies, and copay structures compared to standalone Part D plans. Some MA plans negotiate exclusive deals with pharmacy chains. Compare both options using the Medicare Plan Finder.

Can I use any pharmacy with a Medicare Advantage plan?

MA plans have pharmacy networks with preferred and standard pharmacies. You will pay less at preferred pharmacies. Out-of-network pharmacies may not be covered except in emergencies. Many MA plans include mail-order pharmacy options for maintenance medications at reduced costs.
