No, because you enter the Donut Hole based on
your total retail drug expense, so buying more medications at one time will actually accumulate your total retail drug cost faster and accelerate your entry into the Coverage Gap.
Example of single-month purchase: Enter the Donut Hole in late-March
As a first example, if your monthly retail drug costs are $1,600 and your plan's
Initial Coverage Limit is
$4,660 in 2023 ($5,030
in 2024), you will enter the Donut Hole in the third month -- so late-March ($4,660 / $1,600 = 2.91 months).
Example of multiple-month purchase: Enter the Donut Hole in mid-January
But, if you purchase a 3-month supply of your medications even if you have a copayment of only 2-months, your retail drug costs will remain at the 3-month value for purposes of calculating the start of your Donut Hole ($1,600 x 3 = $4,800).
In this example, since you exceeded your Initial Coverage Limit of $4,660 during the first month by buying a 3-month supply, you will be in the Donut Hole in mid-January - rather than late-March. You will remain in the Donut Hole until you exceed your total out-of-pocket spending (the
TrOOP threshold is $7,400 in 2023 (
$8,000 in 2024).
Bottom Line: Your medication purchasing habits do affect when you go into the Donut Hole.
If you purchase all of your medications early in the year - you will have a higher total retail cost earlier in the year - and probably enter the Donut Hole earlier.
