Are there changes in the Medicare Part D prescription drug coverage for 2020?

Q: Are there changes in the Medicare Part D prescription drug coverage for 2020?

2020 Medicare premiums, deductibles, costsA: Yes. The maximum deductible is slightly higher, and costs while in the “donut hole” will no longer be higher than the costs enrollees pay before entering the donut hole (but the way costs are counted towards reaching the catastrophic coverage threshold is still different while in the donut hole).


The Medicare Part D maximum deductible increased again for 2020, to $435, up from $415 in 2019. But many drug plans have no deductible or a deductible that’s lower than the maximum allowed.

Donut hole

The Medicare Part D program was designed with a gap in coverage: prior to the ACA, beneficiaries’ drug expenses (after the deductible) were covered up to a certain dollar amount (on standard plan designs, the beneficiary pays 25 percent of the cost during this phase), then not covered at all up to another amount, and then more robust coverage would kick in (in most cases, the beneficiary would only pay 5 percent of the cost, or a nominal copay, at this point). The gap in the middle is called the donut hole.

The ACA has been steadily closing the donut hole. Instead of having to pay the full cost of medications while in the donut hole, beneficiaries began paying a percentage of the cost (this chart shows how these percentages have been changing since the ACA began closing the donut hole). The donut hole was scheduled to close in 2020, but it closed one year early, in 2019 instead of 2020, for brand-name drugs.

Stuck in Medicare’s ‘donut hole?’
A prescription discount card could help lower your costs.

The donut hole will close completely, including generic drugs, in 2020. But that just means you’ll pay 25 percent of the cost of your drugs — depending on how your plan is designed, you may still have different costs before and during the donut hole in 2020 and future years. And the donut hole is still relevant due to the way costs are covered and how they count towards your out-of-pocket total and reaching the catastrophic coverage limit.

Standard plans have a deductible, then you pay 25 percent of the cost of drugs until you reach the donut hole. As of 2020, you’ll also pay 25 percent of the cost of drugs while in the donut hole (for both generic and brand-name drugs; brand-names already dropped to this level in 2019). But for example, if your plan is designed with a copay (instead of a 25 percent coinsurance) after the deductible and before the donut hole, your costs will change once you reach the donut hole.

What also changes during the donut hole is how the cost of the drugs is actually being covered. The Kaiser Family Foundation has a helpful chart (Figure 3) that makes it easy to visualize: Before you reach the donut hole, your Part D plan is paying the portion of the cost above your copay or coinsurance. But once you enter the donut hole, the bulk of the cost of your brand-name drugs is being covered by a discount provided by the drug manufacturer (generic drugs are still covered by the enrollee’s coinsurance and Part D plan, rather than a drug manufacturer discount).

In order to get out of the donut hole and move into the catastrophic coverage level (where your costs will be much lower but not necessarily low, depending on your medications), your out-of-pocket spending has to reach $6,350 in 2020 (up considerably from 2019, when it was $5,100). The amount that your plan pays doesn’t count towards reaching this amount. But the amount that’s provided as a discount by the drug manufacturer (for brand-name drugs) does count towards reaching the catastrophic coverage threshold.

So even if your costs in 2020 remain the same when you enter the donut hole, a larger amount is being credited towards your out-of-pocket spending each time you fill the prescription (95 percent of the cost, instead of 25 percent of the cost), helping you to hit the catastrophic coverage threshold sooner.

But don’t confuse this with getting into the donut hole in the first place… to reach that limit, which is $4,020 in 2020, the total cost of your drugs is counted, including the part you pay and the part your plan pays. So for getting into the donut hole, the amount your plan pays is counted. But for getting out of the donut hole, the amount your plan pays is not counted.

In 2020, you enter the donut hole when your spending + your plan’s spending reaches $4,020. And you leave the donut hole — and enter the catastrophic coverage level — when your spending + manufacturer discounts reach $6,350. Both of these amounts are higher than they were in 2019.

So let’s say your plan has a $30 copay for brand-name drugs before you reach the initial coverage limit (ie, before you enter the donut hole), and you buy a drug that costs $100. You’ll pay $30 and your Part D plan will pay $70.

  • The full $100 will count towards getting you into the donut hole (ie, towards the $4,020)
  • Only $30 will count towards the $6,350 total that you’re eventually going to need to hit in order to get into the catastrophic coverage level.

Now let’s say you’ve entered the donut hole and you need to buy that same medication again. It still costs $100, but your plan will only pay $5. The bulk of the cost — $70 — will be covered by the manufacturer discount, and your portion will be $25.

  • $95 will count towards the $6,350 total that you’ll eventually need to reach in order to switch over to catastrophic coverage.

Your Part D plan will keep track of all of this for you, but this is why there’s still an initial coverage limit in 2020, even though the donut hole is closed. It’s really only “closed” in terms of the amount that you’re paying at the pharmacy when you pick up medications — the underlying calculations are still based on the donut hole being there, and that’s still relevant for people who have very high-cost medications.

Seniors saved nearly $27 billion on prescriptions, thanks to the ACA

In January 2017, CMS announced that nearly 12 million people have saved more than $2 billion on prescription drugs since 2010, thanks to the ACA’s progress in closing the donut hole. Of that total, $5.65 billion was realized in 2016 alone.

However, as the Wall Street Journal reports, average out-of-pocket costs for each prescription have been increasing steadily over the years, since they’re generally based on a percentage of the cost of the drug, and drug costs have increased sharply. People who need a significant number of prescriptions will eventually hit the catastrophic cap on their Part D plans, and switch to paying minimal costs for additional medications. But for the person who only has minimal prescription needs, out-of-pocket costs could be higher now than they were in prior years.

This explanation is so confusing as to be meaningless to me. I have an advanced degree in education so one would think I would be able to “get” this.
Maybe it’s all of the chemotherapy rounds that have fogged my powers of comprehension……..but I doubt it.

Tier 3 meds on my plan have a $45 co-pay. When my $45 plus the plan participation gets to $4020 the donut hole starts. Then only my $45 co-pays accumulated with plan participation count toward out of pocket cost. Then, in the donut hole< only the 25% co-pay counts toward the $6350 needed to get out of the hole. Whatever the plan paid while getting to the $4020 break point does not count. The result is we are stuck with the entire $6350 cost. Who benefits? Big Pharma once again gets its inflated prices.

My co-pay for my “main med “ is $807. a month! Very scary! If I get Covid19, and need to fight the side effects with more
required meds, and the ACA is cancelled, my family will have to sell my body for research or transplants or put me on a
ice flow, that is if the Climate Changes hasn’t melted them all!
