Medicare Open Enrollment Updates: What's New for 2026

Medicare open enrollment is your annual window to review, compare, and adjust your Medicare coverage for the coming year. For 2026, the Centers for Medicare & Medicaid Services (CMS) has announced several significant updates to premiums, deductibles, and plan options. These changes can directly affect your monthly costs, prescription drug coverage, and access to doctors or hospitals. Understanding what is new now can help you avoid surprise bills and gaps in coverage. Whether you are currently enrolled in Original Medicare, a Medicare Advantage plan, or a Medigap policy, staying informed about medicare open enrollment updates is the first step to making a confident choice for the year ahead.

This guide breaks down the most important changes for 2026, explains how to compare plans effectively, and walks you through the enrollment process from start to finish. You will also learn how to avoid common mistakes, get help with costs, and find reliable support when you need it. By the end, you will have a clear action plan to maximize your benefits and minimize your out-of-pocket expenses.

Key Medicare Open Enrollment Dates and Deadlines for 2026

The annual Medicare Open Enrollment Period, also known as the Annual Election Period (AEP), runs from October 15 to December 7 each year. For coverage starting on January 1, 2026, your enrollment window closes on December 7, 2025. This deadline applies to changes you make to Medicare Advantage plans, Part D prescription drug plans, and switching between Original Medicare and Medicare Advantage. If you miss this window, you may have to wait until the next open enrollment period to make changes, unless you qualify for a Special Enrollment Period.

It is important to note that the Medicare Advantage Open Enrollment Period (MA OEP) runs from January 1 to March 31 each year. During this time, you can switch from one Medicare Advantage plan to another, or drop your Medicare Advantage plan and return to Original Medicare. However, you cannot switch from Original Medicare to Medicare Advantage during this period, and you cannot make changes to your Part D plan unless you also change your Medicare Advantage plan. For a detailed breakdown of all the dates and deadlines, refer to our guide on 2026 Medicare open enrollment dates.

To stay organized, mark these key dates on your calendar:

• October 15, 2025: Annual Open Enrollment begins.
• December 7, 2025: Last day to enroll or make changes for January 1, 2026 coverage.
• January 1, 2026: New coverage takes effect.
• January 1 to March 31, 2026: Medicare Advantage Open Enrollment Period (for those already in an Advantage plan).

If you are already enrolled in a plan, you will receive an Annual Notice of Change (ANOC) from your insurer by September 30. This document outlines any changes to your plan's costs, coverage, and network for the upcoming year. Review it carefully, as even small changes, like a higher copay for a specialist or a drug moving to a higher tier, can add up over the year. If you do not receive your ANOC, contact your plan directly or log in to your Medicare account to view it online.

Important 2026 Medicare Premium and Deductible Updates

Each year, Medicare releases updated costs for Part A, Part B, and Part D. For 2026, the standard Part B monthly premium is expected to increase, along with the Part B deductible. The Part A deductible for inpatient hospital stays will also rise. These changes are based on the Social Security cost-of-living adjustment and overall healthcare spending trends. While you may not be able to control these amounts, knowing them in advance helps you budget for the year.

The Part D base beneficiary premium is also projected to increase, but the actual amount you pay depends on your plan and income. For 2026, the income-related monthly adjustment amount (IRMAA) thresholds have been updated. If your modified adjusted gross income from 2024 exceeds a certain limit, you may pay an extra IRMAA surcharge on top of your Part B and Part D premiums. The Social Security Administration will notify you if this applies to you.

Because these numbers change every year, it is wise to compare your current plan's costs with other options during open enrollment. Even a small difference in monthly premiums can translate into significant savings over 12 months. Use the official Medicare Plan Finder at Medicare.gov or work with a licensed agent to see exact costs for plans in your area. To understand how the 2026 changes affect your specific situation, read our article on Medicare enrollment updates for 2026.

What Is Changing in Medicare Advantage and Part D for 2026

Medicare Advantage plans (Part C) and standalone Part D prescription drug plans are both undergoing notable changes in 2026. One of the most significant updates is the continuing implementation of the Inflation Reduction Act's prescription drug provisions. Starting in 2025, the Part D out-of-pocket cap was set at $2,000, and that cap remains in place for 2026. This means once you and your plan spend $2,000 on covered drugs, you will not pay any more out-of-pocket for the rest of the year. This cap applies to all Part D plans, including those embedded in Medicare Advantage plans.

Another change for 2026 is the introduction of the Medicare Prescription Payment Plan, a new option that allows you to spread your out-of-pocket drug costs across the year rather than paying them all at once. This can be helpful if you have high-cost medications, but it is not automatic. You must opt in to this program with your plan. Additionally, some Medicare Advantage plans are expanding supplemental benefits, such as dental, vision, hearing, and over-the-counter allowances. However, not all plans offer the same extras, so you need to compare plan details carefully.

It is also important to watch for changes to your plan's formulary (list of covered drugs) and network of doctors and hospitals. Plans can change these from year to year, and what worked well in 2025 may not be the best fit for 2026. If you take a specific medication, check the 2026 formulary to ensure it is still covered and at the same tier. Similarly, if you have a preferred primary care physician or specialist, confirm they remain in-network. These small checks can prevent unexpected costs and disruptions in care.

How to Compare and Choose the Right Plan During Open Enrollment

Choosing a Medicare plan is not a one-size-fits-all decision. Your health needs, prescription medications, preferred doctors, and budget all play a role. During open enrollment, you have the opportunity to switch between Original Medicare, Medicare Advantage, and Medigap policies, as well as change Part D plans. This is the time to do a thorough side-by-side comparison of costs, coverage, and quality ratings.

Start by reviewing your current plan's Annual Notice of Change. Then, use the Medicare Plan Finder or consult with a licensed agent at NewMedicare.com to see what other plans are available in your county. When comparing plans, focus on these key factors:

• Total cost: Add up monthly premiums, deductibles, copays, and coinsurance for the services you use most.
• Provider network: Verify that your doctors and hospitals are in-network for the plan you are considering.
• Prescription coverage: Check that all your medications are on the plan's formulary and at a favorable tier.
• Extra benefits: Look for dental, vision, hearing, or fitness benefits if those are important to you.
• Star rating: The Medicare Star Rating system rates plans on quality and performance, with 5 stars being the highest.

After you narrow down your options, it is wise to talk to a licensed insurance agent. They can explain the nuances of each plan, answer questions about coverage rules, and help you enroll. At NewMedicare.com, our agents are available to help you compare plans from multiple carriers, including Humana, UnitedHealthcare, and Anthem. We can also help you explore Medigap policies if you prefer Original Medicare with supplemental coverage. If you are wondering whether open enrollment is still open for your situation, check our guide on open enrollment deadlines and options.

Medigap and Part D: Separate Decisions, Same Deadline

If you have Original Medicare, you may also have a Medigap policy (Medicare Supplement) and a standalone Part D plan. During open enrollment, you can change your Part D plan, but you generally cannot switch Medigap policies unless you have guaranteed issue rights. Guaranteed issue rights apply in specific situations, such as losing other coverage or moving out of your plan's service area. Outside of these circumstances, Medigap insurers can use medical underwriting, meaning they can reject you or charge higher premiums based on your health.

For Part D, you have the same open enrollment window (October 15 to December 7) to switch to a different plan. Even if you are happy with your current plan, premiums and formularies change, so it is worth comparing alternatives each year. The good news is that the Part D out-of-pocket cap of $2,000 for 2026 provides more predictability. However, plans can still vary in which drugs they cover and their cost-sharing structure.

When evaluating Medigap and Part D together, consider how your total out-of-pocket costs might change. For example, a Medigap plan with a higher premium may offer more comprehensive coverage, but it does not include prescription drug coverage. You need a separate Part D plan. Our team can help you assess whether your current Medigap policy still fits your needs and whether a different Part D plan would lower your drug costs. To learn more about how Medigap and Part D interact during enrollment, read our guide on Medicare open enrollment deadlines.

Common Mistakes to Avoid During Medicare Open Enrollment

Many beneficiaries make avoidable errors during open enrollment that lead to higher costs or gaps in coverage. One of the most common mistakes is assuming that your current plan will automatically renew with the same costs and benefits. As mentioned, plans can change from year to year, and failing to review your ANOC can result in unexpected premium increases or loss of coverage for a needed drug.

Another frequent mistake is focusing only on monthly premiums. A plan with a low premium may have high deductibles or copays that end up costing you more overall. Always calculate your total estimated annual costs, including out-of-pocket maximums. Also, do not forget to check whether your doctors are in-network. A plan that saves you money on premiums but forces you to switch doctors may not be worth it.

Finally, avoid waiting until the last minute. Enrollment closes on December 7, but if you wait until that week, you may have trouble reaching customer service or completing your enrollment online. Start your research early, ideally in October, so you have ample time to compare options and ask questions. If you need help, licensed agents at NewMedicare.com can guide you through the process and help you avoid these pitfalls.

Getting Help with Medicare Costs and Enrollment

If you are struggling to afford Medicare premiums, deductibles, or copayments, there are programs that can help. The Medicare Savings Programs (MSPs) are state-run programs that pay for some or all of your Part A and Part B premiums, and in some cases, deductibles, coinsurance, and copays. Eligibility is based on income and assets, and the rules vary by state. You can apply through your state's Medicaid office or the Social Security Administration.

Another option is the Extra Help program, which helps pay for Part D premiums, deductibles, and copayments. If you qualify, you will pay no more than a small copay for your medications. The Social Security Administration determines eligibility based on your income and resources. You can apply online at ssa.gov or through your local Social Security office.

NewMedicare.com is also here to help you navigate these options. Our licensed agents can explain how MSPs and Extra Help work, and they can help you enroll in a Medicare Advantage, Medigap, or Part D plan that fits your budget.

Your Action Plan for a Smooth 2026 Enrollment

To make the most of the 2026 open enrollment period, follow these steps. First, review your current coverage. Read your Annual Notice of Change and any other materials from your plan. Second, list your current medications, doctors, and expected healthcare needs for the coming year. Third, compare plans using the Medicare Plan Finder or a licensed agent. Focus on total cost, network, and drug coverage. Fourth, decide whether to stay in your current plan or switch. If you are switching, enroll before December 7. Finally, keep records of your enrollment confirmation and mark your calendar for when your new coverage begins on January 1.

Remember that open enrollment is an annual event. Even if you do not need to make changes this year, it is a good habit to review your coverage each fall. Healthcare needs and plan offerings change over time, and staying proactive ensures you always have the best possible coverage for your situation.
