Medicare Open Enrollment 2026: 7 Things Seniors Should Check Before December 7
October 5, 2026
Medicare’s annual open enrollment period is approaching, and millions of older Americans will soon have an opportunity to review their healthcare coverage for the coming year.
For many seniors, this is an important time to look beyond the monthly premium. Changes to prescription drug costs, doctors, hospitals, coverage rules and out-of-pocket expenses can all affect how much a Medicare plan actually costs.
Medicare’s Annual Enrollment Period runs from October 15 through December 7 each year.
Changes made during this period generally take effect on January 1 of the following year.
If you are enrolled in Medicare, here are seven things worth checking before the December 7 deadline.
1. Check Your Medicare Plan’s Costs
Don’t assume that your current plan will cost the same next year.
Review the information your plan sends you about changes to:
- Monthly premiums
- Deductibles
- Copayments
- Coinsurance
- Out-of-pocket limits
- Prescription drug costs
Even a plan that worked well this year may become less attractive if its costs or benefits change.
2. Review Your Prescription Drug Coverage
Prescription medications can represent a significant expense for older Americans.
Before choosing a plan for the coming year, make sure your medications are still covered.
Check:
- Whether your prescriptions are included
- Which tier each medication belongs to
- Your expected copayment
- Whether your pharmacy is preferred
- Whether mail-order options are available
- Whether any coverage restrictions apply
A plan with a low monthly premium isn’t necessarily the cheapest option if your prescription costs are significantly higher.
3. Make Sure Your Doctors Are Still Covered
If you have a doctor you trust, check whether that doctor will continue to participate in your plan.
The same applies to:
- Specialists
- Hospitals
- Clinics
- Physical therapists
- Other healthcare providers
A plan can look attractive on paper but become inconvenient if you have to change doctors or travel farther for medical care.
4. Look at the Plan’s Out-of-Pocket Costs
Premiums aren’t the only number that matters.
Consider how much you could potentially pay during the year if you need significant medical treatment.
Review the plan’s:
Deductible
How much you pay before certain coverage begins.
Copayments
Fixed amounts you may pay for covered services.
Coinsurance
A percentage of the cost that you may be responsible for.
Out-of-pocket maximum
For applicable Medicare Advantage plans, this can be particularly important because it establishes a limit on covered in-network medical expenses.
Understanding these numbers can help you compare the real financial risk of different plans.
5. Don’t Ignore Extra Benefits
Some Medicare Advantage plans offer additional benefits beyond basic medical coverage.
Depending on the plan, these can include benefits related to:
- Dental care
- Vision
- Hearing
- Fitness
- Transportation
- Over-the-counter products
However, benefits and eligibility rules can vary significantly between plans.
Don’t choose a plan simply because it advertises an attractive extra benefit. Make sure the benefit is actually useful to you and understand its limitations.
6. Compare Your Current Plan With Other Options
One of the biggest mistakes seniors can make is assuming that staying with the same plan is automatically the best choice.
You don’t necessarily need to change plans.
But you should compare.
Look at your current plan alongside other available options and consider your own healthcare needs.
For example, someone who rarely visits a doctor may prioritize different features than someone who regularly sees several specialists and takes multiple prescriptions.
7. Don’t Wait Until the Last Week
The enrollment deadline can seem far away when October begins.
But comparing plans takes time.
You may need to review:
- Your medications
- Your doctors
- Your preferred pharmacies
- Your current costs
- Alternative plans
- Coverage details
Starting early gives you more time to ask questions and avoid making a rushed decision.
Medicare Advantage vs. Original Medicare
One of the biggest decisions for some beneficiaries is whether to remain with Original Medicare or choose a Medicare Advantage plan.
Original Medicare generally consists of:
Medicare Part A — hospital insurance
Medicare Part B — medical insurance
Many people with Original Medicare also consider Medicare Supplement Insurance and prescription drug coverage.
Medicare Advantage plans, also known as Medicare Part C, are offered by private insurance companies approved by Medicare.
Each option has different rules, costs and coverage arrangements.
There is no single choice that is best for every senior.
What If You’re Happy With Your Current Plan?
If your current coverage continues to meet your needs, you may decide to stay with it.
However, it’s still worth reviewing the plan’s annual changes.
Your insurer should provide information explaining changes for the upcoming year.
Pay particular attention to changes involving your medications, doctors, premiums and other out-of-pocket costs.
Be Careful With Medicare Scams
Medicare enrollment season is also a time when scammers may become more active.
Be cautious if someone unexpectedly asks for sensitive information while claiming to be helping you enroll.
Never provide financial information simply because someone says you need to act immediately.
Be especially suspicious of anyone who:
- Pressures you to make an immediate decision
- Guarantees you a special Medicare benefit
- Asks for payment to “unlock” Medicare coverage
- Requests your Medicare information through an unexpected message
- Claims to represent Medicare without proper identification
If you’re unsure about an offer, verify it through an official Medicare source.
When Is the Medicare Enrollment Deadline?
The Medicare Annual Enrollment Period runs from:
October 15 through December 7, 2026.
Changes made during the Annual Enrollment Period generally take effect on January 1, 2027.
Because individual circumstances can differ, beneficiaries should check Medicare.gov or speak with a qualified Medicare representative for questions about their specific coverage.
A Simple Medicare Checklist
Before December 7, ask yourself:
☐ Are my doctors still covered?
☐ Are my prescriptions covered?
☐ Has my premium changed?
☐ Have my deductibles or copayments changed?
☐ Is my preferred pharmacy still in-network?
☐ Does the plan’s out-of-pocket limit work for my budget?
☐ Do I actually use the plan’s extra benefits?
☐ Have I compared my current coverage with other available options?
If you can answer these questions, you’ll have a much clearer picture of whether your current Medicare coverage still makes sense for you.
The Bottom Line
Medicare Open Enrollment is an opportunity—not an obligation—to review your healthcare coverage.
You don’t have to change plans simply because another option is available.
But reviewing your coverage each year can help you identify changes in premiums, prescription costs, doctors, benefits and other expenses before the new coverage year begins.
