Medicare is changing in 2027: 7 things seniors need to know before open enrollment

Medicare beneficiaries may see some significant changes when 2027 arrives, and some of them could hit household budgets harder than expected.

Prescription drug deductibles and the annual Part D out-of-pocket limit are rising. Medicare Advantage plans are changing or disappearing in some areas. New negotiated prices for some widely used medications take effect in January. And the standard Medicare Part B premium is also expected to increase.

That makes this fall’s Medicare Open Enrollment period, which runs from October 15 through December 7, particularly important.

Even if you’re happy with your current coverage, don’t assume your Medicare costs, doctors, drug coverage or benefits will remain the same in 2027.

Here are seven changes Medicare beneficiaries should have on their radar.

1. The Part D drug deductible jumps to $700

For people with Medicare prescription drug coverage, one of the clearest changes is an increase in the standard Part D deductible.

The maximum deductible for the defined standard benefit rises from $615 in 2026 to $700 in 2027, according to the Centers for Medicare & Medicaid Services.

That doesn’t necessarily mean everyone will pay a $700 deductible. Individual Part D plans can offer different benefit designs, including lower deductibles or no deductible for certain drug tiers.

But it makes checking the specifics of your 2027 plan especially important.

2. The Part D out-of-pocket limit is also increasing

One of the biggest Medicare changes in recent years was the introduction of a firm annual limit on what beneficiaries have to spend out of pocket for covered Part D prescription drugs.

That protection remains in place, but the limit is indexed and can increase.

In 2026, the threshold is $2,100. For 2027, it rises to $2,400. Once a beneficiary reaches that threshold in qualifying out-of-pocket spending, the person generally owes no additional cost sharing for covered Part D drugs for the remainder of the year.

For someone taking expensive medications, that’s a potentially important $300 increase in maximum annual exposure.

3. More Medicare-negotiated drug prices take effect

January 2027 also marks the second year that prices negotiated directly by Medicare take effect under the Medicare Drug Price Negotiation Program.

The first negotiated prices took effect in 2026. Another 15 high-spending Part D drugs were selected for negotiated prices beginning in 2027, including medications used to treat diabetes, obesity, cancer, respiratory disease and other serious conditions.

The effect on an individual beneficiary’s pharmacy bill won’t necessarily be identical to the reduction in a drug’s negotiated price. What you actually pay depends on your medication, your Part D plan and where you are in the benefit structure.

Still, anyone taking one of the affected medications should compare the drug’s 2027 cost under available plans rather than simply renewing the same plan.

4. The standard Part B premium is expected to rise

The final 2027 Medicare Part B premium has not yet been announced, so be wary of articles presenting a 2027 figure as final.

The Medicare Trustees currently estimate that the standard Part B premium will rise from $202.90 a month in 2026 to about $209.50 a month in 2027. The actual amount will be established later this year.

For most Social Security recipients, the Part B premium is deducted directly from their monthly benefit.

That means part of whatever Social Security cost-of-living adjustment beneficiaries receive for 2027 may effectively be absorbed by higher Medicare costs.

5. Some Medicare Advantage members may lose their current plans

For people enrolled in Medicare Advantage, perhaps the most important piece of mail this fall could be the plan’s Annual Notice of Change—or a notice that the plan won’t be available next year.

Insurers are pulling back from some Medicare Advantage markets for 2027, and some beneficiaries will have to choose new coverage. Humana alone has indicated that plan exits will affect roughly 600,000 of its members for 2027.

Even when a Medicare Advantage plan remains available, its premium isn’t the only thing that can change. Provider networks, drug formularies, copayments, deductibles and supplemental benefits such as dental, vision, hearing, transportation or over-the-counter allowances can also be different.

Medicare advises Advantage members to carefully review the Annual Notice of Change their plan sends each fall because it details changes in coverage and costs taking effect in January.

Don’t look only at the monthly premium. Check whether your doctors and hospitals are still in network and whether your medications are still covered at an affordable tier.

6. Prior authorization should become more electronic and transparent

Another less visible change begins in 2027 and could eventually make navigating Medicare Advantage easier for patients and their doctors.

CMS rules require affected health insurers, including Medicare Advantage organizations, to implement new electronic systems that allow providers to exchange prior-authorization information more efficiently beginning in 2027.

The changes are intended to reduce some of the paperwork and delays associated with getting insurer approval for covered medical care.

That doesn’t mean prior authorization disappears. Medicare Advantage plans can still require authorization for many services. But the process is moving toward greater electronic access and standardized information exchange.

7. Higher-income beneficiaries should remember the two-year lookback

People with higher incomes can pay substantially more for Medicare Part B and Part D because of the Income-Related Monthly Adjustment Amount, commonly known as IRMAA.

For 2027, the important number isn’t necessarily what you earn in 2027. Medicare generally determines the surcharge using tax information from two years earlier—meaning 2025 income will ordinarily be used for 2027 premiums.

The final 2027 income brackets and surcharges have not yet been announced.

People whose income has fallen substantially because of certain life-changing events, including retirement, marriage, divorce or the death of a spouse, may be able to ask Social Security to reconsider an IRMAA determination rather than simply accepting a surcharge based on an income level that no longer reflects their circumstances.

What Medicare beneficiaries should do this fall

The biggest mistake may be doing nothing.

Medicare Open Enrollment runs from October 15 through December 7, and coverage selected during that period generally begins January 1, 2027.

Before automatically renewing, beneficiaries should compare their existing coverage with the 2027 options available where they live. Check premiums and deductibles, but also look at prescription drug costs, pharmacy networks, doctors and hospitals, maximum out-of-pocket costs and supplemental benefits.

Pay particular attention to any Annual Notice of Change or plan termination notice arriving in the mail.

For people with several prescriptions, it can be worth entering every medication and dosage into the official Medicare Plan Finder rather than comparing plans based solely on their premiums.

And anyone who finds the choices overwhelming can get free, individualized Medicare counseling through their state’s State Health Insurance Assistance Program, or SHIP.

The bottom line

Some of the biggest Medicare reforms of the past several years remain in place in 2027, including limits on Part D prescription drug spending and Medicare’s ability to negotiate prices for certain expensive medications.

But some costs are moving upward at the same time. The standard Part D deductible rises to $700, the drug out-of-pocket threshold increases to $2,400, and Part B premiums are projected to climb as well.

Meanwhile, changes in the Medicare Advantage market mean some seniors may discover that the plan they have now isn’t the plan they’ll have available in January.

The takeaway isn’t that everyone needs to switch coverage. It’s that 2027 is not a year to let Medicare coverage renew on autopilot. A careful review this fall could reveal changes that affect your doctors, prescriptions and wallet long before the first medical bill of the new year arrives.
