Whether you are enrolled in traditional Medicare or a Medicare Advantage plan, Medicare covers the prescription drugs you get from the pharmacy under Medicare Part D. The vast majority of people with Medicare, 50.5 million in 2023, are enrolled in a Part D drug plan. Here’s what you need to know about Medicare Part D coverage and costs in 2024 and why you should take a close look at your options for next year during this annual open enrollment period.
Don’t assume that your current Part D drug plan will cover your drugs in 2024, even if it does in 2023. Rather, assume that your costs will go up a lot if you didn’t check which Part D plan was likely to save you the most money based on your drug needs, during the Medicare open enrollment period (October 15-December 7). Each year, these Part D private insurance plans can change dramatically. Kaiser Family Foundation offers key facts about Part D plans in 2023.
As a general rule, close to three in four people enrolled in traditional Medicare and a Part D plan will pay higher costs the following year, if they do not look at their options and switch plans.
In 2024, there are 709 prescription drug plans available nationally, according to the Kaiser Family Foundation. If you are in traditional Medicare, you will be able to choose from among 15 to 24 Part D plans in your state. 16 national Part D prescription drug plans, with monthly premiums ranging from $6 to $111. The average premium is $43.
Premiums: Premiums are typically higher for Part D plans offering enhanced benefits, lower cost-sharing and/or low or no deductibles. Standard Part D plans have a base monthly premium in 2024 of $34.70, but it could be higher or lower depending upon multiple factors. Part D “enhanced” plans that charge no or a low deductible have a base monthly premium of $55.50 in 2024.
If your annual income is $103,000 or higher, you pay a supplemental premium of between $12.90 and $81 a month.
Standard deductible: The standard and highest possible deductible—the amount you must pay before your coverage begins—is $545, up from $505 in 2023.
If you have traditional Medicare: You typically will be able to choose among 24 Part D drug plans. Depending upon the state you live in, your options range between 19 and 28.
If you are in a Medicare Advantage plan: You typically will have a choice of around 35 Part D drug plans.
Cost-sharing: For non-preferred brand-name drugs, coinsurance could be as high as 40-50 percent and as low as $0 for preferred generics, depending upon the Part D plan you choose. You also are likely to pay 15-25 percent coinsurance for preferred brand drugs.
Typically you’ll pay about $1 for preferred generics and $5 for generics. You’ll pay around $44 copay for preferred brands, 45 percent coinsurance for non-preferred drugs, and 25 percent coinsurance for specialty drugs.
Maximum out-of-pocket: The most you will pay out of pocket for drugs you purchase through Part D is $3,300 in 2024, even though the out-of-pocket spending limit is rising to $8,000 or $12,447 in total drug costs). But the $8,000 includes the value of the manufacturer discount on the price of brand-name drugs during the coverage gap phase of the benefit. If you only use brand-name drugs, you will only have to pay around $3,300 out of pocket.
Also, keep in mind that in 2025, your maximum out-of-pocket cost for drugs covered through Part D will be $2,000 because of the Inflation Reduction Act.
Costs in each coverage phase: After you have paid your deductible, you are in the initial coverage phase, where you generally will pay around 25 percent of the cost of both brand-name and generic drugs until your drug costs total $5,030. You will then be in the coverage gap phase, where you will be responsible for about 25 percent of the cost of your drugs. Once your out-of-pocket drug costs, including the deductible, but not your Part D premium, total $8,000 in the coverage gap phase (in fact, around $3,300 plus manufacturer discounts,) you will be in the catastrophic coverage phase. At that point, you will pay nothing more for your covered drugs.
If you qualify for a low-income subsidy (LIS) or Extra Help: You will have lower out-of-pocket costs, depending upon the Part D plan you choose and the drugs you use. You should pay $4.50 for each generic drug that is covered and $11.20 for each brand-name covered drug. Around 13 million people with Medicare qualify for extra help with their prescription drug costs. There are 198 Part D drug plans for which you will not pay a premium. You can also choose a “non-benchmark” plan and pay a portion of the monthly premium.
You should get Extra Help automatically if you have full Medicaid benefits or are receiving SSI benefits. If not, you can apply for Extra Help through the Social Security Administration. To qualify, generally, an individual’s countable income needs to be below $21,870 and your assets need to be below $16,600.
If you need insulin: The Inflation Reduction Act limits your monthly copayment to no more than $35 in all phases of Part D coverage. However, that limit applies only to insulin in a plan’s formulary, not all insulin products.
If you need a vaccine: Vaccine costs are covered in full for vaccines that are on the Part D formulary.
