While Medicare Parts A and B offer standard coverage for all enrollees, your prescription costs and coverage will hinge on the specific Part D drug plan you choose. It's common for these plans to change from year to year, though. And some of those changes could result in higher costs. Here are a few ways your Medicare Part D plan may have changed in 2026.
1. Your premiums may have risen
Although some $0 premium Medicare Part D plans exist, many people pay a premium each month for drug coverage. If your premium costs have increased this year, you'll need to factor that into your budget.

2. Your deductible may have increased
Most Medicare Part D plans have an annual deductible you need to meet. It's not uncommon for deductibles to increase, so make sure you know what amount you're looking at this year. You'll generally need to pay the full cost for your medications until that deductible is met.
3. You may be looking at higher drug copays
Medicare Part D plans use formularies to group medications into different tiers. The higher the tier, the higher your out-of-pocket costs will generally be.
It may be that the medications you take have moved into a higher tier this year. If so, you could be looking at higher costs. If money is tight and you're struggling to afford your medications, you may want to talk to your doctor about generics or other alternatives. There may also be a drug assistance program you qualify for based on your income, so it pays to do some research.
4. Your preferred pharmacy network may have changed
It's a pretty standard practice for Medicare Part D drug plans to have a preferred pharmacy network. If that pharmacy network changed in 2026, it's an important thing to know about.
Going outside your plan's preferred pharmacies could mean paying a lot more for your medications -- as much as the full cost, in fact. You may be able to get reimbursed if you go outside of your plan's network, but then you'll need to submit claims and hope they're processed quickly. Your best bet, therefore, is generally to stay within your plan's preferred network.
Stay in the know
Healthcare might be a huge retirement expense of yours, especially in the context of medication. It's important to be aware of changes to your Part D drug plan so you're able to cover the cost of your medications with as little stress as possible.
