Medicare Open Enrollment 2026: 12 Important Things to Check Before December 7
Published: 28 October 2026 | SHOW ROOM
Medicare Open Enrollment is underway across the United States, giving millions of eligible Americans an opportunity to review their health and prescription drug coverage for 2027.
The annual enrollment period began on 15 October 2026 and ends on 7 December 2026.
For people already enrolled in Medicare, this is an important opportunity to compare plans, review potential changes and decide whether their existing coverage still meets their needs.
Even if you are happy with your current Medicare plan, it is worth checking the details.
Premiums, prescription drug coverage, pharmacy networks, healthcare providers and out-of-pocket costs can change from one year to the next.
This guide explains 12 essential things to review before the December deadline, how to compare Medicare plans and where to find trustworthy assistance.
When Is Medicare Open Enrollment 2026?
Here are the key dates for the current enrollment period.
| Important event | Date |
|---|---|
| 2027 plan comparisons become available | October 2026 |
| Medicare Open Enrollment begins | 15 October 2026 |
| Medicare Open Enrollment ends | 7 December 2026 |
| New coverage generally begins | 1 January 2027 |
| Medicare Advantage Open Enrollment | 1 January–31 March 2027 |
During the autumn enrollment period, eligible people can make permitted changes to Medicare Advantage and prescription drug coverage.
Changes made during this period generally take effect on 1 January 2027.
What Can You Change During Medicare Open Enrollment?
Depending on your existing coverage, you may be able to:
Switch from Original Medicare to a Medicare Advantage plan.
Switch from Medicare Advantage back to Original Medicare.
Change from one Medicare Advantage plan to another.
Join, switch or drop a Medicare Part D prescription drug plan, subject to eligibility and coverage rules.
Keep your current coverage if it continues to meet your needs.
The available choices depend on your situation.
Medicare Open Enrollment is not the same as the Initial Enrollment Period for people joining Medicare for the first time.
12 Important Things to Check Before December 7
1. Review Your Current Medicare Plan
Start by checking the coverage you already have.
Look at the services you used during 2026 and consider whether your needs may change in 2027.
Ask yourself whether your current plan remains suitable for your healthcare needs and budget.
2. Read Your Annual Notice of Change
Medicare Advantage and Part D plans generally send an Annual Notice of Change explaining important updates for the following year.
This document can identify changes to premiums, benefits, cost-sharing and other coverage details.
Do not discard it without reviewing the information.
3. Compare Monthly Premiums
The monthly premium is one part of the overall cost of Medicare coverage.
Some plans may advertise low or zero additional premiums, but that does not mean healthcare services are entirely free.
Compare the full financial picture rather than choosing a plan based only on its monthly premium.
4. Check Your Prescription Drugs
Prescription drug coverage can vary between plans.
Before choosing coverage for 2027, prepare a current list of medications.
Include the drug names, dosages and how frequently you take them.
Then check whether each plan covers those medications and what restrictions or costs may apply.
5. Review Pharmacy Networks
Your preferred pharmacy may not have the same status under every prescription drug plan.
Some plans use preferred pharmacies or different cost-sharing arrangements.
Check whether your usual pharmacy participates and whether another accessible pharmacy would offer more suitable costs.
6. Confirm Your Doctors and Hospitals
Provider networks are especially important when comparing Medicare Advantage plans.
Check whether your preferred doctors, specialists and hospitals participate in the plan for 2027.
Do not rely solely on an old provider directory.
Contact the plan and, where appropriate, the healthcare provider to confirm current participation.
7. Understand Deductibles and Copayments
A deductible is an amount you may need to pay before certain coverage begins.
Copayments and coinsurance are other forms of cost-sharing.
Review these costs for the services you are likely to use.
A plan with a lower premium may have higher costs when you receive care.
8. Check the Annual Out-of-Pocket Limit
Medicare Advantage plans have annual limits on covered Part A and Part B out-of-pocket costs, although the applicable amount depends on the plan and coverage.
Original Medicare generally does not have an annual out-of-pocket limit for covered Part A and Part B services unless you have other coverage that provides financial protection.
Understanding these differences is important when comparing options.
9. Review Extra Benefits
Some Medicare Advantage plans offer additional benefits, which may include dental, vision or hearing-related coverage.
Availability and limits vary.
Before choosing a plan because of an advertised benefit, check eligibility requirements, participating providers, annual allowances and exclusions.
10. Consider Your Travel and Living Arrangements
Think about where you expect to live and receive healthcare in 2027.
If you spend significant time in another state or travel frequently, check how the plan handles care outside its usual service area.
Emergency coverage and routine non-emergency care may be treated differently.
11. Compare Overall Annual Costs
Do not make a decision based on one number.
Estimate the combined cost of premiums, prescription medications, deductibles and expected medical services.
Your actual expenses will depend on the care you need.
12. Review Your Options Before the Deadline
Avoid waiting until the final day if possible.
Give yourself enough time to compare plans, contact providers and ask questions.
If you decide to make a change, ensure the appropriate plan receives your enrollment request by the applicable deadline.
Original Medicare vs Medicare Advantage: Key Differences
Two major coverage arrangements are Original Medicare and Medicare Advantage.
| Feature | Original Medicare | Medicare Advantage |
|---|---|---|
| Administration | Federal Medicare programme | Medicare-approved private insurance companies |
| Core coverage | Part A and Part B | Includes Part A and Part B benefits |
| Provider choice | Generally any provider accepting Medicare | Often subject to plan network rules |
| Prescription coverage | Usually requires separate Part D coverage | Often included, depending on plan |
| Extra benefits | Generally limited without other coverage | May include additional benefits |
| Annual out-of-pocket limit for Part A and B services | Generally none without supplemental coverage | Plan-specific annual limit |
Neither option is automatically best for everyone.
The appropriate choice depends on healthcare needs, providers, medications, finances and personal preferences.
What Is Changing for Medicare in 2027?
Medicare plan details are updated each year.
For 2027, the Centers for Medicare & Medicaid Services has published information about Medicare Advantage and Part D plan availability and projected premiums.
However, national averages do not necessarily reflect the cost of a particular plan in your county.
A plan's premium may decrease while certain copayments, benefits or network arrangements change.
Therefore, the most useful comparison is between the specific plans available to you.
Prescription Drug Coverage
Prescription drug plans can change their covered medication lists, pharmacy arrangements and cost-sharing.
Review your current medications using the official Medicare Plan Finder.
Medicare Advantage Benefits
Plans may revise their additional benefits, service areas and participating providers.
Confirm details using the plan's current documents rather than relying on previous-year information.
Costs and Premiums
Some national premium averages are projected to decline for 2027, according to CMS.
That does not mean every beneficiary will pay less.
Your actual costs depend on your coverage and circumstances.

What Happens If You Do Nothing?
If you are satisfied with your current coverage and the plan continues to be available, you generally do not need to re-enroll simply to keep it.
However, your plan's benefits and costs may change for 2027.
If a plan is ending or your coverage is otherwise affected, different notices and enrollment rules may apply.
Always review communications from Medicare and your insurer.
Medicare Advantage Open Enrollment in 2027
There is another enrollment period from 1 January through 31 March 2027 for people who are already enrolled in Medicare Advantage.
During this period, eligible Medicare Advantage members can generally make one permitted change, such as switching to another Medicare Advantage plan or returning to Original Medicare.
This period is not a general second opportunity for everyone with Original Medicare to make any desired coverage change.
How to Avoid Medicare Enrollment Scams
Scammers may exploit the enrollment period by impersonating government agencies or insurance representatives.
Be cautious if someone:
Requests your Medicare number unexpectedly.
Demands immediate payment to secure a supposed benefit.
Claims you must switch plans without providing verifiable information.
Pressures you to disclose financial details.
Sends suspicious links requesting sensitive personal information.
Promises benefits that cannot be confirmed in official plan documents.
Use Medicare.gov or the official Medicare telephone service to verify uncertain information.
Do not share your Medicare number with unverified callers or websites.
