What is the Donut Hole in Medicare?

The donut hole is the coverage gap phase in Medicare Part D plans. During this coverage phase, the beneficiary has a temporary limit on their Medicare Part D coverage. Thus, after spending a specific amount on a drug plan, you are responsible for a certain percentage of the retail cost of your drug.

In 2024, the coverage gap discount is 75%. Therefore, the beneficiary is responsible for 25% of drug costs in the donut hole.

How Does the Medicare Donut Hole Work?

Prescription drug coverage consists of multiple stages. The first phase starts on your prescription drug plan’s effective date – often January 1.

This primary phase involves reaching your deductible – up to $545. You are responsible for paying 100% of this cost.

After meeting the deductible, you enter the initial coverage phase. During this phase, you are only responsible for copayments. After the cost of drugs reaches $5,030, you fall into the donut hole.

While in the donut hole, you will need to pay 25% of the cost for generic and brand-name drugs until what you pay out-of-pocket reaches $8,000. The final phase, catastrophic coverage, kicks in when you leave the gap.

You are responsible for just $4.15 for generic medications and $10.35 or 5% of your drug costs in the catastrophic coverage phase, whichever costs more. You will remain in this phase until your out-of-pocket spending meets $8,000. Once this threshold is met, you will no longer be required to pay coinsurance for your drugs for the rest of the calendar year.  The monthly statements you obtain from your plan provider should show your current status regarding the donut hole.

How Do I Get Out of the Donut Hole?

Once your costs for prescription drugs meet $7,400, you will move into the next coverage phase. When this happens, catastrophic coverage kicks in automatically.

During the catastrophic coverage phase, you cover $4.15 for generic medications and $10.35 or 5%, whichever costs more, and your policy will settle 95% of the remaining costs until you meet $8,000 in total annual out-of-pocket costs. Then, the cycle repeats annually.

Do Medicare Advantage Plans Cover the Donut Hole?

Private insurance companies manage Medicare Part C plans, often including prescription drug benefits. These plans work similarly to standard Medicare Part D plans.

Thus, Medicare Advantage Prescription Drug Plans still involve coverage gaps. A Medicare Advantage plan might cover some generic medications in the donut hole, but these do not serve to close the gap faster due to their lower prices.


Why is there a donut hole in Medicare Part D?
The donut hole was created to incentivize people to use generic drugs. Thus, keeping beneficiary costs low and reducing Medicare expenses on the program level.
Do all Medicare Part D plans have a donut hole?
All Medicare Part D plans follow the same drug phases. Every prescription coverage plan involves the gap known as the donut hole.
Will I enter the donut hole if I receive Extra Help?
Those who get Extra Help pay reduced amounts for their prescriptions throughout the year, so they are unlikely to reach the donut hole.
How do I know if I am in the donut hole?
You will receive an Explanation of Benefits (EOB) notice in the mail from your carrier for each month you utilize your drug plan. The EOB notice informs you of your current coverage phase, and you can see how close to the donut hole you are based on the dollar amount required to reach the next phase.
What costs count toward the donut hole?
The cost of the drugs on your plan’s formulary will count toward you entering the donut hole. For example, if you purchase a $500 drug and your copay is $75, the full $500 will count toward your initial coverage phase.
Does the donut hole discount only apply to drugs on my Medicare Part D plan’s formulary?
Yes, the donut hole discount only applies to drugs on your prescription drug plan’s formulary unless your plan approved a formulary exception.
Can I find Medicare Part D plans without the donut hole?
No, all Medicare prescription drug plans include the donut hole. If you anticipate reaching the donut hole and have trouble with costs, you can apply for Extra Help with Medicare Part D.
