Medicare Part D

Before You Switch Drug Plans, Know What the $2,100 Cap Covers

In Easton, Medicare shoppers have two very different ways to get help paying for prescriptions — and the choice you make shapes more than just your pharmacy bill. It changes how the rest of your Medicare works, too.

The first path is Original Medicare paired with a stand-alone Part D drug plan. The second is a Medicare Advantage plan that already includes drug coverage (often called an MA-PD). Both give you access to Part D benefits, including the annual out-of-pocket cap — $2,100 in 2026 and $2,400 in 2027. But what happens around that drug coverage is where the two paths part ways.

Two structures, one benefit

A stand-alone Part D plan does one job: it covers prescription drugs. You keep Original Medicare (Parts A and B) for hospital and doctor visits, and your drug plan sits alongside it. Many people who choose this path also carry a Medigap policy to help with the costs Original Medicare doesn't pay.

A Medicare Advantage plan bundles things together. It replaces the way you get your Part A and Part B benefits, usually adds prescription drug coverage, and often folds in extras like dental or vision. The drug portion still has to follow the same Part D rules Medicare sets each year.

Easton is in Northampton County, where residents can shop from a wide slate of both stand-alone Part D plans and Medicare Advantage plans that include drug coverage. The specific number of options changes each year, and you can see the current list on medicare.gov.

What stays the same

No matter which door you walk through, the core Part D rules apply in both 2026 and 2027:

• The most you can pay out of pocket for covered drugs in a year is $2,100 in 2026 and $2,400 in 2027.
• The maximum deductible any Part D plan can charge is $615 in 2026 and $700 in 2027.
• The old coverage gap, known as the "donut hole," is gone. Since 2025, Part D has just three phases: deductible, initial coverage, and catastrophic.
• You can ask to spread your drug costs across the year through the Medicare Prescription Payment Plan, whether your coverage is stand-alone or part of an Advantage plan.
• Higher-income enrollees may owe an IRMAA surcharge on their Part D premium, starting above $109,000 in income for a single filer in 2026.

Every plan must also publish a formulary (its list of covered drugs) and a pharmacy network. Those details vary from plan to plan — which is why two people on the same medication can have very different experiences.

What changes when you switch

This is where readers often get tripped up. If you're on Original Medicare with a stand-alone Part D plan and you switch to a Medicare Advantage plan that includes drugs, your old Part D plan ends automatically. Your doctor and hospital coverage now flows through the Advantage plan's network and rules.

Going the other direction, if you leave Medicare Advantage and return to Original Medicare, you'll usually want to pick up a stand-alone Part D plan right away so you don't end up without drug coverage — and possibly a late enrollment penalty later on.

One quirk to know: if you're enrolled in most types of Medicare Advantage plans and you sign up for a stand-alone Part D plan, Medicare treats that as a signal you want to leave the Advantage plan. You'll be moved back to Original Medicare. That surprise has landed on more than one Pennsylvania retiree, so it's worth pausing before you enroll.

There's also the Medigap question. Medigap policies only work with Original Medicare, not Medicare Advantage. If you drop Advantage to return to Original Medicare, you may or may not be able to buy a Medigap policy without medical underwriting, depending on your situation and timing.

When you can make the change

Two windows matter most:

• Annual Enrollment Period: Oct. 15 – Dec. 7. During this window you can switch between Original Medicare and Medicare Advantage, add or drop a Part D plan, or change from one drug plan to another. Changes take effect Jan. 1.
• Medicare Advantage Open Enrollment: Jan. 1 – March 31. If you're already in a Medicare Advantage plan, you can switch to a different Advantage plan or drop back to Original Medicare and pick up a Part D plan.

Special Enrollment Periods also exist for life events like moving, losing employer coverage, or qualifying for Extra Help.
