Learn how to switch Medicare plans and find potential savings during enrollment. Discover key deadlines and comparison steps to maximize your benefits.
Last Updated: October 25, 2026
Quick Summary
Yes, you can switch Medicare plans to save money during the annual enrollment period from October 15 through December 7 each year. Switching often reduces costs by comparing total annual expenses, premiums, deductibles, copays, and prescription drug costs, rather than just the monthly premium.
Your Medicare coverage doesn't stay the same year to year. Plans change. Costs shift. New options appear.
At SafelyRetire, we help Medicare beneficiaries understand how to switch Medicare plans to save money. Most people don't review their coverage annually, so they stay in plans that no longer fit their needs or budget.
According to research on Medicare plan switching, relatively few beneficiaries voluntarily switch plans during the annual enrollment period, even when switching could reduce their costs.
Your health needs evolve, your prescriptions change, premiums and deductibles rise, and provider networks shift. Any of these could mean your current plan costs hundreds of dollars more than a better alternative.
You can't switch Medicare plans whenever you want. Federal rules create specific windows, and missing these deadlines can lock you into your current plan for an entire year.
Medicare Annual Enrollment Period (AEP)
The main enrollment window runs from October 15 through December 7 each year. During this period, you can:
Any changes you make during AEP take effect January 1 of the following year. This is your primary opportunity to switch Medicare plans each year.
Medicare Advantage Open Enrollment Period (OEP)
If you're already enrolled in a Medicare Advantage plan, you get a second chance to switch. From January 1 through March 31 each year, you can:
Changes made during this window take effect the first of the following month, giving you a three-month window if you miss AEP or find your plan isn't working after January 1.
Special Enrollment Periods (SEP)
Certain life events let you change plans outside the regular enrollment windows. These include:
If a qualifying event happens, contact Medicare within 60 days to learn about your options.
When you compare Medicare Advantage plans, you're evaluating more than the monthly premium. Plans change annually, and the factors below most often decide whether a switch actually saves money, several of which beneficiaries discover too late.
Premiums and deductibles
Medicare Advantage premiums vary by insurer and plan type, from $0 to $50 or more monthly. But premium is only part of the cost equation: deductibles, copayments, and coinsurance add up, and a low-premium, high-deductible plan can cost more in a year with a hospital stay than a higher-premium, lower-deductible plan.
According to 2026 Medicare cost data, the 2026 Medicare Part B deductible is $283, up from $257 in 2025.
Provider networks and referrals
Medicare Advantage plans use networks of doctors, hospitals, and specialists. If your current doctor isn't in next year's network, you'll need to switch doctors or pay out-of-network costs. Two network details drive real costs:
Prescription drug costs are often the biggest surprise for Medicare beneficiaries. If you're not comparing Part D plans annually, you're likely overpaying.
How Part D Works
Medicare Part D is prescription drug coverage from private insurers.
According to Medicare prescription drug information, the 2026 Medicare Part D out-of-pocket maximum is $2,100, $100 higher than in 2025.
Formulary Changes
Formularies change every year. A drug that costs $10 on your current plan might cost $50 elsewhere.
When you switch Medicare plans, you need to check whether your specific medications are covered and at what cost. This single factor can save you hundreds of dollars annually.
Comparing Part D Plans
To compare prescription drug plans effectively:
Many beneficiaries find that their least-expensive plan changes year to year. The plan that saved you money in 2025 might be expensive in 2026.
The monthly premium is what you see; out-of-pocket costs are what you actually pay.
Build a total-cost worksheet before you switch
Most comparison tools show only a premium and a deductible, that is not a cost comparison. Build a worksheet for each plan using your expected care, then compare totals side by side:
| Cost category | How to estimate it | Where to find the number |
|---|---|---|
| Monthly premium | Plan premium × 12 | Plan Summary of Benefits |
| Annual deductible | Amount you pay before coverage begins | Plan Summary of Benefits |
| Primary care visits | Copay × expected visits per year | Plan provider directory and copay schedule |
| Specialist visits | Copay × expected visits per year | Plan copay schedule |
| Lab and imaging | Copay or coinsurance × expected use | Plan copay schedule |
| Hospital stay | Coinsurance per day or per stay × expected stays | Plan Summary of Benefits |
| Prescription drugs | Use the plan finder's annual drug cost estimate | Medicare Plan Finder |
| Out-of-pocket maximum | Worst-case annual exposure | Plan Summary of Benefits |
Run the worksheet for your current plan and at least two alternatives. The lowest-premium plan is frequently not the lowest total cost once you enter actual visits, drugs, and expected procedures, a $0-premium Medicare Advantage plan often costs more in total than one with a modest premium.
The Medigap trap: leaving Medicare Advantage is not always reversible
This is the cost consideration most switching guides skip.
Federal guaranteed-issue protections are narrow, generally applying only in specific situations such as when a Medicare Advantage plan leaves your area or you lose certain employer or union coverage.
Before switching away from Medicare Advantage, check your state's Medigap rules. A handful of states offer broader guaranteed-issue rights or annual "birthday" enrollment windows than federal law requires; most do not.
Out-of-pocket maximums are not created equal
Estimate your realistic annual cost, not the sticker price
To estimate your costs with a specific plan:
That total, not the premium, is the number that tells you whether switching will actually save money.
Switching Medicare plans involves specific steps and deadlines.
Step 1: Review Your Current Coverage (Weeks 1-2)
Gather your Medicare card, current plan documents, and a list of your doctors and medications.
Step 2: Compare Available Plans (Weeks 2-4)
Use Medicare.gov's plan finder tool or work with an independent broker.
Step 3: Verify Network Status (Week 3)
Step 4: Enroll During Open Enrollment (October 15 - December 7)
During the annual enrollment period, you can enroll in a new plan through:
Complete your enrollment before December 7. Changes take effect January 1.
Step 5: Confirm Your New Coverage (December)
After enrolling, verify your new plan information:
Step 6: Notify Your Current Plan (if switching from Medicare Advantage)
Your new plan will handle the disenrollment automatically.
Step 7: Update Your Healthcare Providers (December-January)
Notify your doctors' offices of your new insurance information. Provide them with your new member ID and plan details.
Common Mistakes to Avoid
Watch out: Missing the enrollment deadline locks you into your current plan for an entire year.
Watch out: Failing to verify network status before enrolling can mean discovering your doctor isn't covered after January 1.
Switching Medicare plans is one of the most direct ways to reduce healthcare costs, but only if you compare the right options and understand your real costs, not just the premium.
At SafelyRetire, we help Medicare beneficiaries navigate these decisions. We work with multiple insurance companies, so we can compare Medicare Advantage plans and evaluate Part D prescription drug coverage, explaining options in plain English and the total cost of each plan, not just the monthly premium.
If you're uncertain whether your current plan still fits your needs, or if you want expert guidance on whether switching makes sense for your situation, get in touch with us. We'll review your coverage, compare your options, and help you make a decision that keeps more money in your pocket.
The estimated $1.5 billion in savings expected to lower recipients' out-of-pocket spending in 2026 comes from Medicare changes and better plan choices. Those savings are only available if you take action during the enrollment period. Discover expert guidance on whether Medicare Advantage is right for your situation, or explore specific Part D options in your area to see how much you could save.
You can switch Medicare plans during the Annual Enrollment Period (October 15-December 7) without penalties. Medicare Advantage enrollees also have the Medicare Advantage Open Enrollment Period (January 1-March 31) to switch to another Medicare Advantage plan or return to Original Medicare. Special Enrollment Periods apply if you experience qualifying life events, such as losing employer coverage or moving out of your plan's service area. Missing these windows may result in late enrollment penalties.
Compare your current plan's total annual costs, premiums, deductibles, copayments, coinsurance, and out-of-pocket maximums, against alternative plans. For 2026, the Medicare Part D out-of-pocket maximum is $2,100, and the Part B deductible is $283. Review whether your current doctors and hospitals are in a new plan's network, and check if your medications are on the formulary.
Switching between Medicare Advantage plans during the Medicare Advantage Open Enrollment Period (January 1-March 31) is straightforward. Switching from Medicare Advantage to Original Medicare during the Annual Enrollment Period (October 15-December 7) may trigger Medigap underwriting, meaning you could be denied coverage or charged higher premiums if you have pre-existing conditions. Some states offer guaranteed-issue Medigap rights for certain situations, so timing and your health status matter significantly.
If you miss enrollment deadlines, you may face late enrollment penalties that are permanent. However, you may qualify for a Special Enrollment Period if you experienced a qualifying event, such as losing employer coverage, moving, or becoming eligible for Extra Help (low-income assistance). Contact Medicare immediately to explore your options. Some situations allow penalty forgiveness, but acting quickly is essential.
