What is the Medicare donut hole?
The coverage gap that used to sit in the middle of every drug plan year, what replaced it, and why it still matters for understanding your costs.
The donut hole was the coverage gap built into Part D from the beginning. It was one of the most disliked features of Medicare, and it is now gone.
How it used to work
A Part D year moved through phases. After the deductible, you were in initial coverage paying copays. Once total drug spending reached a threshold, you fell into the coverage gap and paid a much larger share yourself. Once your own spending reached a second, higher threshold, you reached catastrophic coverage and your costs dropped again.
The gap in the middle was the donut hole. People on expensive medications would hit it around midyear and face a sudden jump in cost, often without warning.
What replaced it
The gap has been eliminated and replaced with a hard annual cap on what you pay out of pocket for covered drugs. Once you reach the cap, your covered prescriptions cost you nothing for the rest of the calendar year.
For anyone on high cost medication this is a substantial change and it is worth revisiting decisions made under the old rules. See how the cap works.
Why you still hear the term
Two reasons. People who lived through it still use the phrase, and some plan materials and older articles still reference the phases.
If someone tells you to watch out for the donut hole, they are describing a structure that no longer applies. The concept worth understanding now is the annual cap.
If you previously chose a plan, or chose not to take an expensive medication, because of the donut hole, that decision was made under rules that no longer exist. It is worth re-running the numbers.
What still varies through the year
Your costs are not flat across a plan year even now.
- In January you may be paying toward a deductible, so early fills can cost more.
- Through the year you pay tier based copays or coinsurance.
- Once you reach the annual out of pocket cap, covered drugs cost nothing for the remainder of the year.
So a medication that costs one amount in February and another in October is normal, and it does not mean anything went wrong.
Spreading the cost
There is now an option to pay your out of pocket drug costs in level monthly amounts across the year rather than all at once when they occur. For someone facing a large bill in January this can be genuinely useful, since it smooths the same total cost over twelve payments.
It does not reduce what you pay. It changes when you pay it. Ask your plan about it if a large early year cost would be difficult.

Common follow-up questions
Does the donut hole still exist?
No. The coverage gap has been replaced by an annual out of pocket cap on covered drugs.
What happens after I hit the cap?
Your covered prescriptions cost you nothing for the rest of the calendar year. It resets each January.
Why do my drug costs change during the year?
Usually the deductible early in the year, then tier based copays, then nothing once you reach the annual cap.
