Closing the Donut Hole

The Affordable Care Act, which was signed into law on March 23, 2010, made changes to Medicare Part D to reduce your out-of-pocket costs when you reach the donut hole, including:

  • In 2010, if you had expenses in the coverage gap, you should have received a $250 rebate from Medicare.
  • Beginning in 2011, if you reached the donut hole in a given year, you received a discount on the total cost of your medications while in the gap. The discount started out at 50% for brand name drugs in 2011 and 7% for generic drugs, and it grew steadily each year.
  • The donut hole was originally scheduled to be eliminated in 2020, with enrollees paying 25% of the cost of their medications while in the donut hole (the same as the percentage they pay before reaching the donut hole, if they have a standard Part D plan design).
  • But the Bipartisan Budget Act of 2018 closed the donut hole one year early for brand-name drugs: In 2019, Part D enrollees paid just 25% of the cost of brand-name drugs until they reached the catastrophic limit (ie, the top of the donut hole). There was still a donut hole price differential for generic drugs in 2019 (enrollees paid 37% of the cost of generics while in the donut hole that year) but that dropped to 25% in 2020.

Coverage Gap Has Been "Closed" But Costs Can Still Increase Mid-Year If You Reach the Donut Hole Threshold

So as of 2020, these changes effectively closed the coverage gap for both generic and brand-name medications. Rather than paying 100% of the costs (as was the case prior to the ACA's changes), your responsibility is now 25% of the costs.

Although the coverage gap has technically been eliminated, it is important to remember that you will still be responsible for paying 25% of the costs of your prescription drugs once your drug costs reach the initial threshold for entering the donut hole, and that will continue until your costs reach the catastrophic coverage level.

If you have a standard plan design, you'll also pay 25% of your drug costs prior to reaching that initial coverage limit, but many plans have different coverage designs and provide lower pricing on drugs before you reach the donut hole. So even though the donut hole has been "closed," you might find that your medication costs increase partway through the year, once you reach the donut hole threshold.

For example, you might have a plan that has a $10 copay for one of your medications before you reach the initial coverage limit (bottom threshold of the donut hole) but then switches to having you pay 25% of the cost once you hit that point. Assuming you do reach that threshold, your out-of-pocket costs might be quite a bit higher once you're paying 25% of the cost, depending on the full cost of the drug. If you take a lot of medications or ones that are expensive, the costs can still be burdensome, even though the donut hole has technically closed. It's important, therefore, that you are aware of resources that may be able to help you.

How Many People Reach the Donut Hole?

According to a 2018 report from the Kaiser Family Foundation, more than 5 million Medicare Part D plan participants reached the coverage gap in their prescription drug coverage in 2016. This gap—known as the "donut hole"—occurs after an enrollee has reached a specified level of drug spending (the initial coverage limit) but has not spent enough to reach the catastrophic coverage threshold. And as described above, people can still experience higher costs while in the donut hole, even though it's technically closed.

People with chronic conditions, such as Alzheimer's disease or diabetes, have a much higher risk of reaching the coverage gap than people without chronic medical needs. If you only need an occasional prescription, you're not likely to reach the coverage gap, since it doesn't begin until your total drug spending reaches the initial coverage limit, which is $4,130 in 2021.

Prior to the ACA's changes, people had to pay for 100% of the cost of their drugs while in this gap. But the percentage of the cost that enrollees have to pay has been reduced to 25% as a result of the ACA. It's important to understand, however, that drug costs have also increased during that time. So while you may be paying a lower percentage of the cost now than you were a few years ago, it's still possible that your total cost each time you refill a medication could be increasing, due to the increasing cost of medications. And the upper threshold of the donut hole (where catastrophic coverage kicks in and medication costs decline significantly) increases a little each year too, which results in more out-of-pocket spending for Part D enrollees with extensive prescription needs. As of 2021, the catastrophic coverage level begins once total drug spending reaches $6,550.

Medication Compliance While in the Donut Hole

Particularly before the ACA began closing the donut hole, some people stopped taking their medication once they reached the donut hole. 2007 was the first time that people were enrolled for the full year in Part D coverage, and the ACA didn't start closing the donut hole until several years later. So enrollees who reached the donut hole in 2007 were responsible for 100% of their medication costs until they reached the catastrophic coverage threshold.

A Kaiser Family Foundation analysis of 2007 medication utilization among Part D enrollees found that about 15% of people who reached the coverage gap stopped their medications.

For example, 10% of people in a Medicare drug plan who were taking oral medications for the treatment of type 2 diabetes who reached the coverage gap stopped taking their medications. For a person with diabetes, stopping medication for even a short period of time can cause serious and immediate health problems.

And despite the fact that the Part D donut hole has been closed, the cost of some medications can still be prohibitively high even if the enrollee is only paying 25% of the costs. So let's take a look at some ways to save money if you end up in the donut hole.

How Can I Lower My Drug Costs in the Donut Hole?

Consider switching to a less-expensive drug One of the easiest ways to lower your prescription drug costs in the donut hole is to switch to lower cost or generic drugs, as available and appropriate. You can talk with your healthcare provider about the medications you are currently taking to find out if there are generic or less-expensive brand-name drugs that would work just as well as the ones you're taking now.

For example, if you take Zoloft for depression, you can save money by switching to sertraline, the generic version of Zoloft.

Order a 3-month supply of your medication
If you have a chronic condition, such as diabetes, ask your healthcare provider to write a prescription for a 90-day supply of your medication. Many Medicare drug plans offer a discount if you use their mail-order program. Also, your local pharmacy may give you a 90-day supply of your medications for the same price as the mail-order plan.

Explore national and community-based charities
Several national and community-based charities have programs that can help you with the cost of your medications. A good place to start is the website of Benefits Checkup, a service of the National Council on Aging. The site provides easy-to-read information about the Medicare prescription drug plan, how to find additional benefits and how to apply for extra help.

Look into pharmaceutical assistance programs
Many major drug companies offer assistance programs for people enrolled in a Medicare drug plan. You can find out whether a Patient Assistance Program is offered by the manufacturers of the drugs you take by visiting the Pharmaceutical Assistance Program page on the Medicare website.

All you need to do is find your medication in the alphabetical list. The site then provides information about available savings programs and a link to the drug company's site to obtain information on how to apply for assistance.

Consider state pharmaceutical assistance programs
Many states offer help with paying drug plan premiums and other drug costs. You can find out if your state has a program by visiting the State Pharmaceutical Assistance Program (SPAP) page on the Medicare website.

The National Conference of State Legislatures has a comprehensive summary of SPAPs across the country and how they work.

Apply for the Extra Help program
If you have a Medicare drug plan and have limited income and resources, you may qualify for extra help paying for your prescription medications.

This extra help, available through the Social Security Administration, can save you money by paying for part of your monthly premiums, annual deductibles and prescription copayments.

Is There Anything That I Can Do to Avoid the Donut Hole?

Yes. You can avoid the donut hole if you are able to keep the total cost of your drugs below $4,130 in 2021. If your Part D plan offers lower-cost drugs prior to the initial coverage limit (for example, a $10 copay instead of requiring you to pay 25% of the cost of your drugs), your out-of-pocket spending will stay lower if you don't reach the initial coverage limit. One of the best ways to do this is to ask your healthcare provider to switch you to generic medications, if available and appropriate.

This initial coverage limit is quite a big higher than it was in 2011, when the ACA first started to provide discounts in the donut hole (that year, the donut hole began once your total drug spending reached $2,840). But thanks to the ACA, the donut hole itself is also considerably less painful than it was back when enrollees had to pay the full cost of their medications.
