What’s changing in Medicare Part D for 2027?
For 2027, three key Part D figures go up. The annual out-of-pocket cap on covered drugs rises to $2,400, the maximum deductible a plan can charge rises to $700, and the national base beneficiary premium rises to $41.33, according to CMS. Each one may affect you a little differently, depending on the medications you take.
These are federal limits and reference amounts, not the price of any particular plan. Your own costs will still depend on the plan you pick, the drugs you take, the tier each drug sits on and the pharmacy you use. Two people in the same plan can have very different yearly costs because their prescriptions are different.
Because these numbers change every year, it’s smart to recheck your drug coverage during Annual Enrollment, which runs October 15 – December 7, 2026. Changes you make then take effect January 1, 2027. Our 2027 Annual Enrollment checklist walks you through the full review, step by step, from your plan notice to your final decision.
| Part D item | 2026 | 2027 |
|---|---|---|
| Out-of-pocket cap on covered drugs | $2,100 | $2,400 |
| Maximum deductible | $615 | $700 |
| National base beneficiary premium | $38.99 | $41.33 |
What does the $2,400 out-of-pocket cap mean for you?
In 2027, once your out-of-pocket spending on covered Part D drugs reaches $2,400, you generally pay nothing more for covered drugs for the rest of the year. Think of it as a ceiling on your costs at the pharmacy counter, not a bill you’ll necessarily ever reach in a given year.
If you take only a few lower-cost generics, you may never come close to the cap. If you take one or more high-cost brand-name or specialty drugs, you might reach it early in the year. Either way, the cap gives you a clear upper limit to plan around, which can make budgeting for the year a little easier.
Keep in mind what the cap doesn’t include. Your monthly plan premium doesn’t count toward it, and drugs that aren’t on your plan’s drug list generally don’t count either. That’s one more good reason to confirm that every medication you take is covered by the plan you choose for 2027.
The cap applies the same way in stand-alone Part D plans and in Medicare Advantage plans that include drug coverage. It resets each January, so spending in 2026 doesn’t carry over into 2027. If you expect to reach the cap again next year, plan ahead for the higher $2,400 ceiling when you set your household budget.
How does the $700 Part D deductible work?
The deductible is what you pay for covered drugs before your plan starts sharing the cost. In 2027, a Part D plan can set a deductible of up to $700. Some plans set a lower deductible, and some apply it only to certain drug tiers while covering lower-cost generics right away.
Because plans design their deductibles differently, two plans with similar premiums can feel very different in January and February. One may cover your generics from the first day of the year, while another may ask you to pay the full plan price for your medications until you’ve met the deductible.
When you compare plans, look at how the deductible applies to your drugs. The total estimated yearly cost shown in the Medicare Plan Finder combines the premium, deductible and copays into one number, which makes it much easier to compare plans fairly. Be sure to enter your actual pharmacy, since prices can differ from one pharmacy to the next.
Why does the $41.33 base beneficiary premium matter?
The national base beneficiary premium is a reference figure Medicare uses for calculations. Its most direct effect on you is the Part D late enrollment penalty, which is figured as 1% of the base premium for each full month you went without Part D or other creditable drug coverage after you first became eligible.
In 2027, that base is $41.33. So a 20-month gap works out to 20 × 1% × $41.33 = $8.27, rounded to $8.30 a month and added to your premium. Because the base changes yearly, the penalty amount is recalculated each year, and it generally lasts for as long as you have Part D coverage.
It’s important to know that the base premium isn’t what your plan charges. Plan premiums vary, and some may be higher or lower than $41.33. You can estimate a penalty with our Part D penalty calculator; keep in mind it gives an estimate, not a quote or an official determination.
Who may notice the 2027 Part D changes most?
People who take high-cost brand-name or specialty drugs are most likely to notice the 2027 changes, because they’re the ones who reach the deductible quickly and may hit the $2,400 cap. If you take only low-cost generics, the federal changes may matter less than your own plan’s premium and copays.
If you hit the cap in 2026, expect to pay somewhat more before reaching it in 2027, since the ceiling rises by $300. If you met the full deductible in 2026, your plan’s 2027 deductible may be higher too, up to $700. Budgeting for those early-year costs now can soften the impact in January.
People with a gap in drug coverage should pay attention as well. Because the base beneficiary premium rose to $41.33, any late enrollment penalty is recalculated a little higher for 2027. And anyone whose plan is changing its drug list or pharmacy network may notice those plan-level changes more than the federal ones.
What is the Medicare Prescription Payment Plan?
The Medicare Prescription Payment Plan is an option that lets you spread your out-of-pocket Part D drug costs into monthly payments through the year, instead of paying the full amount at the pharmacy counter. It doesn’t lower your total costs, but it can make them more predictable from month to month.
This can help if you take expensive medications and would otherwise face large pharmacy bills early in the year, especially before you reach your deductible or the out-of-pocket cap. Deductible costs, if your plan has one, tend to land early in the year. Instead of one big payment at the counter, you’d receive monthly bills from your plan for the amounts you owe.
It isn’t the right fit for everyone. If your drug costs are modest, paying as you go may be simpler. If you’re interested, contact your Part D or Medicare Advantage plan to ask how to opt in, or ask Kris to help you think through whether it makes sense for your prescriptions and your monthly budget.
If you do sign up, remember that your regular monthly plan premium is still billed separately, so you’ll want to keep track of both amounts in your household budget. Before you opt in, ask your plan to explain exactly how its monthly billing works, when payments are due and what happens if a payment is late.
The payment plan changes when you pay, not how much. If cost itself is the concern, ask whether you may qualify for Extra Help or whether a different plan covers your drugs at a lower total cost.
How do you check whether your plan still covers your drugs?
Check your plan’s 2027 drug list (formulary) for each medication you take, note the tier and confirm your pharmacy is still in network. Your Annual Notice of Change will flag major changes, but comparing your exact list yourself is the surest way to avoid surprises at the pharmacy in January.
Plans can add or remove drugs, move them to different tiers or add rules like prior authorization and quantity limits. One of the most helpful things an agent can do is catch a plan that’s about to stop covering a medication you rely on, before that change costs you money or forces a last-minute switch.
Start with our Rx drug lookup or the Medicare Plan Finder. Have your exact drug names, doses and quantities handy, along with the pharmacy you prefer. The more precise your list, the more accurate your cost estimates will be when you compare 2027 plans. If a drug is dropped, ask your doctor whether a covered alternative would work just as well for you.
- Is each drug still on the formulary?
- Did any drug move to a higher tier?
- Are there new prior authorization or step therapy rules?
- Is your pharmacy still preferred or in network?
- Would mail-order lower your cost for maintenance drugs?
How can Kris help you review your 2027 drug coverage?
