What Does It All Cost

All Medicare plans have some level of cost-sharing. Here are some of the costs you might be responsible for paying.


A fixed, monthly amount you pay your insurer for your plan coverage.


What you pay before your insurer begins to pay its share of the costs. Some part C plans charge an annual deductible for medical and/or prescription drug costs.


A defined amount you pay each time you receive care. Copays vary by services and benefits.


A percentage you pay for medical services after you’ve met your deductible. Insurers set their own percentages.

Out of pocket maximum

Medicare Advantage plans include an annual limit on how much you pay for covered services. When you reach that limit, you don’t pay additional costs for covered services. Original Medicare doesn’t include this limit.

Breaking Down Medicare Part D Cost Sharing for 2021

There are several stages of cost sharing with Part D plans. Most Medicare drug plans have a coverage gap, often referred to as the Medicare “donut hole.” In the coverage gap, there is a temporary limit on what the plan covers.

Part D Formularies and Your Costs

Part D plans have a drug list, or formulary, that shows all the brand-name and generic drugs it covers.

Many plans have a tiered formulary, where drugs are divided into groups called "tiers".

In general, the lower the tier, the lower the cost to you.

Generic drugs typically fall into Tier 1.
