Medicare Donut Hole: What is a donut hole in Medicare?

By:Michael Quinn Published onAugust 23, 2023June 11, 2026 Updated onJune 11, 2026

In the world of Medicare, there exists a peculiar term called the “donut hole.” No, we are not referring to the sweet, deep-fried confectionery that tempts our taste buds. Instead, the doughnut hole refers to a unique Coverage gap in the Medicare Part D drug plan (Medicare’s prescription drug program). Understanding this concept is essential for those relying on Medicare for their healthcare needs. That’s because it directly impacts out-of-pocket expenses for prescription medications.

In this article we’ll discuss:
  • Medicare Part D Donut Hole
  • When do you enter the donut hole?
  • When do you get out of the donut hole?
  • How to avoid the Medicare donut hole?
  • When is the Medicare Donut Hole Closed?
  • Will the Prescription Drug Part D Coverage Gap Go Away?
  • How does donut hole work with Medicare Advantage & Medicare Part D costs?
  • Conclusion

Medicare Part D Donut Hole

The donut hole is a phase within your Medicare Part D Prescription Drug Coverage (It is not related to medications that are covered under your Medicare Part B). It is where beneficiaries must bear a more significant portion of their prescription costs. It is a point in your drug coverage, marked by a specific dollar amount. Once you spend a certain amount on medications and reach a certain threshold, beneficiaries enter the “donut-hole”. This is where they are responsible for a higher percentage of costs until they reach the next threshold.

Though the concept may appear confusing at first. Being aware of it is paramount for beneficiaries to effectively manage their healthcare costs. It will also help them make informed decisions regarding drug coverage. Let’s dive a little deeper into the specifics and how it affects beneficiaries.

When do you enter the donut hole?

The donut hole begins once the total amount spent on covered drugs by both the person and their insurance plan reaches a certain threshold. At this point, the individual enters the initial coverage stage. In other words, you’re in the donut hole. This is where you’re responsible for paying 25% of the cost for brand-name drugs and 25% of the cost for generic drugs (the drug manufacturer pays 75%).

It is important to note that the cost that applies towards reaching the threshold includes the following: The amount paid by the person and any drug manufacturer discounts received for brand-name drugs.

Once the individual reaches the catastrophic coverage threshold, their out-of-pocket costs decrease significantly. It is crucial for individuals enrolled in Medicare drug plans to be aware of this and plan their medication expenses accordingly. 

When do you get out of the donut hole?

Once you exceed the threshold of cost, you will be out of the “donut-hole” and you’ll enter the catastrophic coverage phase. When closing the donut-hole, it’s important to note that not all expenses count towards reaching the threshold.

For example, Part D premiums don’t help you with this coverage phase. Payments made by your drug plan and manufacturer discounts are among the costs that don’t contribute to reaching the out-of-pocket limit.

How to avoid the Medicare donut hole?

Navigating the complex landscape of Medicare can be overwhelming. However, there are strategies to help minimize the impact. One approach is to carefully select a Medicare Part D coverage plan and review its costs. Comparing different Medicare plans and understanding their Formulary can allow beneficiaries to determine which plan provides the most comprehensive Medicare Part D coverage for their specific medication needs.

Another way to avoid the donut-hole is to take advantage of cost-saving initiatives, such as generic drugs or mail-order pharmacy services. By opting for lower-cost alternatives and prescription delivery services, beneficiaries can stretch their medication budget. This can potentially delay reaching the threshold. It is also crucial for individuals to monitor their medication usage throughout the year and be aware of their total costs. Tracking expenses and consulting with a Medicare expert can ensure beneficiaries stay informed. It helps to take these necessary steps to avoid falling into the Medicare donut-hole.

When is the Medicare Donut Hole Closed?

In the past, beneficiaries had to cover the full cost of their medications while in the gap. However, with the passing of the Affordable Care Act in 2010, a plan was put into motion to close this gap in coverage completely. This plan aims to reduce the out-of-pocket costs for beneficiaries during the Medicare prescription drug coverage gap.

The closure is being phased in over several years, with incremental improvements each year. In the coming years, it is expected that it will be completely closed. This means that beneficiaries will no longer have to pay the higher percentage of their covered prescription drug costs out-of-pocket while in the gap. Instead, they will pay a lower percentage, making their medications more affordable and accessible. 

Will the Prescription Drug Part D Coverage Gap Go Away?

The future of the Part D prescription drug plan gap is a popular topic. Originally, the gap was implemented as a cost-saving measure and was intended to encourage individuals to use generic drugs, thus reducing overall healthcare expenditures. However, over the years, this has proven to be a burden for many Medicare beneficiaries, who face significant out-of-pocket costs when they fall into this gap. As a result, there have been ongoing discussions about the need to eliminate or modify this coverage gap stage.

The good news for 2023 is that the coverage gap phase is set to be fully eliminated in 2025. This means that Part D enrollees will no longer face heightened costs during this phase. Instead, they will continue to pay their regular cost-sharing amounts for prescription drugs throughout the year.

The elimination of the Medicare coverage gap phase is a significant improvement for beneficiaries. It removes a financial burden that many have faced in the past and aligns with the goal of providing more affordable access to necessary medications.

How does donut hole work with Medicare Advantage & Medicare Part D costs?

The donut-hole is also connected to Medicare Advantage Plans that have a Part drug plan. These plans are also known as MAPD plans or Part-C.

MAPD plans, which are private insurance plans that provide Medicare benefits, often include Part D plan drug coverage as part of their offerings. Therefore, it can also apply to those enrolled in MAPD plans. Since these plans often include drug coverage as part of their offerings, the coverage gap commonly can also apply to those enrolled in these plans.

Conclusion

Out-of-pocket drug costs can take a toll on your wallet. Whether you have a Medicare Supplement insurance plan or an MAPD plan, your annual drug costs can be significant. Even if you don’t take any medications today, you should still get a Part-D plan to avoid a Penalty. However, if you take medications and fill a prescription, your Part-D plan should keep your overall costs lower compared to not having one. 

It’s understandable if all of this is overwhelming. That’s why we created an easy to learn course to get you familiar with the Medicare system.
