What Medicare Open Enrollment means for 2027 coverage
Medicare Open Enrollment, also called the Medicare Annual Election Period, runs from October 15 through December 7, 2026. During this window, people with Medicare can change their coverage for 2027. The plan must receive your enrollment request by December 7 for the change to take effect on January 1, 2027.
You can join, drop, or switch Medicare Advantage plans, change Medicare Part D prescription drug plans, or switch between Medicare Advantage and Original Medicare. What makes sense depends on your current coverage, health needs, prescriptions, preferred doctors, and budget.
Although the enrollment window doesn’t begin until October 15, Medicare’s 2026 handbook tells beneficiaries to start comparing their current coverage with 2027 options on or around October 1. That gives you time to review plan changes before making a decision.
Review the official Medicare Open Enrollment dates and options
Start with your current plan notice
If you’re already enrolled in Medicare Advantage or a Part D drug plan, your plan should send an Annual Notice of Change. This notice explains changes to premiums, deductibles, copayments, covered services, drug formularies, provider networks, and rules for the next plan year.
Read the notice alongside your current plan documents. A plan that worked well in 2026 may have different costs or coverage rules in 2027. Pay special attention to changes that affect services you use regularly, such as specialist visits, physical therapy, dental benefits, insulin coverage, transportation, or mail-order prescriptions.
Make a short list of anything that changed. You don’t necessarily need to switch plans, but you should understand what staying will cost and whether your doctors and medications remain covered.
Who can make changes during Open Enrollment?
Open Enrollment is available to people who already have Medicare and want to change their health or prescription drug coverage for the following year. Your options depend on the coverage you have now.
| Current coverage | Possible changes |
|---|---|
| Medicare Advantage | Switch to another Medicare Advantage plan, return to Original Medicare, and join a standalone Part D plan if needed. |
| Original Medicare without Part D | Join a Medicare drug plan and review whether supplemental coverage may be appropriate. |
| Original Medicare with Part D | Switch to another Part D plan or move to a Medicare Advantage plan that includes drug coverage. |
| Medicare Advantage with prescription coverage | Change to another Medicare Advantage plan or return to Original Medicare and select separate drug coverage. |
Switching from Medicare Advantage to Original Medicare requires extra care. You may want a Medigap policy to help pay certain out-of-pocket costs, but Medigap insurers can use medical underwriting in some situations. The timing and availability of Medigap protections depend on your circumstances and state rules, so don’t cancel a plan until you understand how the replacement coverage would work.
What to compare before choosing a 2027 plan
1. Your doctors, hospitals, and other providers
For Medicare Advantage, check whether your primary care doctor, specialists, hospitals, pharmacies, and other frequently used providers are in the plan’s network for 2027. A provider listed in a search tool isn’t always enough—network information can change, and you may want to confirm directly with the doctor’s office and the plan.
Pay attention to the type of network. Health maintenance organization plans generally require you to use network providers except for emergencies and certain covered situations. Preferred provider organization plans may offer out-of-network coverage, but you’ll often pay more.
2. Every prescription you take
Make a complete medication list before using Medicare Plan Compare. Include the drug name, strength, dosage, how often you take it, and whether you use a preferred pharmacy or mail order.
Check each plan’s formulary to see whether your medications are covered. Then review the tier, copayment or coinsurance, prior authorization requirements, step therapy rules, quantity limits, and participating pharmacies. A plan with a low monthly premium can still be expensive if your prescriptions are placed on higher tiers or your preferred pharmacy is outside the plan’s preferred network.
3. Total yearly cost, not just the premium
Compare the likely yearly cost of premiums, deductibles, copayments, coinsurance, and other services you expect to use. For Medicare Advantage, also check the plan’s annual out-of-pocket limit for covered medical services.
Consider your normal pattern of care. Someone who rarely visits a doctor may prioritize a low premium, while someone with regular specialist appointments or planned procedures may save money with a higher-premium plan that has lower cost-sharing.
| Check | Why it matters |
|---|---|
| Monthly premium | Shows what you pay regularly, including any plan premium in addition to Part B costs. |
| Deductible | Can affect what you pay at the beginning of the year, especially for prescription drugs. |
| Copayments and coinsurance | Determine your share when you receive care or fill prescriptions. |
| Out-of-pocket limit | Helps show your maximum exposure for covered medical services in a Medicare Advantage plan. |
| Drug costs | May vary widely based on the formulary, pharmacy network, drug tier, and coverage rules. |
4. Benefits you actually use
Medicare Advantage plans may offer additional benefits, such as dental, vision, hearing, fitness, transportation, or over-the-counter allowances. Check the details rather than relying on the benefit headline. A dental benefit may have an annual limit, a restricted provider network, waiting rules, or services that aren’t covered.
Focus on benefits that affect your real expenses. An allowance you rarely use shouldn’t outweigh a major increase in specialist costs or a change to your prescription coverage.
What to gather before comparing plans
A little preparation makes Medicare Plan Compare much easier. Have these details nearby:
- Your Medicare card and current plan name
- Your list of prescriptions, including dosage and quantity
- The names of your doctors, specialists, hospitals, and preferred pharmacies
- Your Annual Notice of Change and Evidence of Coverage documents
- Recent bills or an estimate of your typical healthcare spending
- Notes about planned procedures, regular treatments, or travel needs
If someone helps you manage your coverage, decide in advance what information you’re comfortable sharing. Avoid giving your Medicare number to unsolicited callers, texts, or emails. Medicare representatives generally won’t call unexpectedly to ask for personal information unless you’ve given permission for a specific contact.
How to compare and change coverage
Beginning October 1, use the official Medicare Plan Compare tool to review available 2027 options in your ZIP code. Enter your current prescriptions and pharmacies so the tool can estimate drug costs more accurately.
Compare Medicare plans for 2027Compare several plans side by side, then open the plan details for the options that look promising. Confirm the provider network, formulary, premiums, deductibles, cost-sharing, out-of-pocket limits, and restrictions before enrolling.
During Open Enrollment, you can enroll through Medicare’s plan comparison tool or through the plan itself. Save or print the confirmation number and enrollment details. If you enroll by December 7, your new coverage should begin January 1, 2027.
If you need impartial help, contact your State Health Insurance Assistance Program, known as SHIP. SHIP counselors provide free, personalized Medicare counseling and can help you compare plans without selling insurance.
Important exceptions and common mistakes
Don’t assume automatic renewal is the best option
Your current plan may renew automatically, but that doesn’t mean its 2027 costs, network, or drug coverage will remain the same. Review the plan even if you’re generally satisfied.
Don’t confuse Open Enrollment with Initial Enrollment
Open Enrollment is for people who already have Medicare and are changing coverage for the next year. It isn’t the same as the seven-month Initial Enrollment Period for someone first becoming eligible for Medicare at age 65, or for certain people qualifying because of a disability.
Check whether you qualify for cost assistance
People with limited income and resources may qualify for Medicare Savings Programs or Extra Help with Part D costs. Medicaid, Supplemental Security Income, or a Medicare Savings Program can also lead to automatic Extra Help in qualifying situations.
Extra Help rules and amounts can change. If your financial situation has changed, review your eligibility rather than assuming you won’t qualify.
Check Medicare Savings Program eligibility Check official help with Medicare drug costsBe careful when moving from Medicare Advantage to Original Medicare
Returning to Original Medicare may require you to arrange separate Part D coverage and may leave you responsible for costs that a Medigap policy could help cover. Before making the change, confirm whether you can buy the Medigap policy you want and what it will cost.

For now, collect your plan notice, medication list, provider names, and recent healthcare costs. Starting October 1, compare the 2027 options available in your area. During October 15 through December 7, make the change only after confirming the plan’s network, formulary, total costs, and effective date.
