Medicare Part D prescription drug plans and some Medicare Advantage plans have what is known as a “donut hole” or “coverage gap,” which is a temporary limit on how much a Prescription Drug Plan will pay for prescription drug costs.
The Medicare donut hole is going away, however. Starting in 2019, Medicare prescription drug plan beneficiaries will pay no more than 25 percent of their brand name prescription drug costs and 37 percent of their generic drug costs until they reach the level of catastrophic coverage.1
Learn more about the Medicare donut hole, including how it can affect your out-of-pocket costs, below.
All cost information is for the year 2019 unless otherwise noted.
Neither Medicare Part A or Medicare Part B provide prescription drug coverage. Medicare beneficiaries who want coverage for prescription drugs have the option to enroll in a standalone Medicare Part D plan or a Medicare Advantage plan that includes prescription drug coverage.
Medicare Part D plans are sold by private insurance companies and can help cover the costs of some prescription drugs.
There are four main coverage phases associated with Part D plans:
Note: People who get Extra Help (a program that helps certain people with limited incomes pay for some of their Part D out-of-pocket costs) will not enter the Medicare donut hole.
Most Medicare Part D plans have an annual deductible you must meet before Medicare begins paying its share for covered drugs.
Specific deductible amounts can vary widely from plan to plan. If your Part D plan does not have a deductible, you do not have to pay out-of-pocket costs to reach the initial coverage phase (below).
Once you’ve met your Part D deductible, you enter the initial coverage phase. During the initial coverage phase, you pay a coinsurance or copayment for covered drugs, and Medicare pays the rest.
Typically, once you and your Part D plan have spent more than $3,820 (in 2019) in a single year on prescription drugs, you’ll enter the donut hole.2
Once you enter the donut hole in 2019, you are responsible for paying a larger portion of your drug costs (no more than 25 percent of the plan’s cost for covered brand-name prescription drugs and 37 percent of the plan's cost for generic drugs) until you reach $5,100.3
As noted above, the Medicare donut hole is shrinking in 2019, thanks to the Bipartisan Budget Act of 2018.1
Some of the costs beneficiaries are responsible for during the donut hole phase are lower in 2019 than they were in 2018. Starting in 2020, Part D beneficiaries will pay 25 percent of the cost of brand name and generic drugs during the coverage gap until reaching catastrophic coverage spending limit.
Once you’ve paid $5,100 on prescription drugs, you enter the catastrophic coverage phase.
When you enter catastrophic coverage, you only pay a small coinsurance or copayment for covered prescription drugs for the remainder of the year.
Not everyone will enter all four of these phases. In fact, depending on how many prescription drugs you buy and how much each drug costs, it is possible to never even leave the deductible phase.
The following out-of-pocket costs contribute to the overall costs that can get you out of the donut hole phase and into the catastrophic coverage phase:
Some drug companies that make brand-name prescription drugs sign agreements with Medicare to participate in the Medicare Coverage Gap Discount Program.
Companies that participate in this program must offer discounts on covered brand-name drugs to individuals who have entered the donut hole.
The entire price (including the discount the drug company pays) will count toward getting you out of the donut hole and into catastrophic coverage.4
For generic drugs, only the amount you pay will count toward getting you out of the coverage gap.
Costs that do not count towards getting out of the donut hole include:
Most Medicare beneficiaries have the option to enroll in Medicare Advantage (Medicare Part C), which is an alternative to Original Medicare (Medicare Part A and Part B) that is sold by private insurers.
Unlike Original Medicare (which does not include coverage for prescription drugs), many Medicare Advantage plans cover prescription drugs. Some plans may offer additional benefits not covered by Medicare, such as dental, vision and hearing coverage.
A Medicare Advantage plan with prescription drug coverage can help you save money on your covered drugs, which can help lessen the impact of the Part D donut hole.
