Your Options During Medicare Fall Open Enrollment
Medicare’s Fall Open Enrollment Period runs from October 15 through December 7 each year. Any coverage changes you make during this period generally take effect January 1 of the following year.
Even if you’re happy with your current coverage, it’s a good idea to review your plan every year. Medicare Advantage and Part D plans can change their costs, benefits, provider networks and prescription drug coverage from one year to the next.
During your annual review, check:
- Are your doctors and hospitals still in your plan’s network?
- Are your prescription medications still covered?
- Have your copays, deductibles or premiums changed?
- Has your preferred pharmacy changed?
- Have any additional benefits changed?
- Does your current coverage still fit your health care needs and budget?

Option 1: Enroll in or Change a Medicare Advantage Plan
A Medicare Advantage plan, also known as Medicare Part C, is an alternative way to receive your Medicare Part A and Part B benefits through a Medicare-approved private insurance company.
Medicare Advantage plans:
- Include your Medicare Part A and Part B benefits.
- Usually include Medicare Part D prescription drug coverage.
- May include additional benefits such as routine dental, vision and hearing services.
- May require you to use doctors, hospitals and other providers within the plan’s network.
- May require prior authorization for certain services or medications.
- Have an annual maximum limit on covered out-of-pocket medical expenses.
During Fall Open Enrollment, you can:
- Switch from one Medicare Advantage plan to another.
- Switch from Original Medicare to Medicare Advantage.
- Change from a Medicare Advantage plan with drug coverage to another Medicare Advantage plan.
- Drop a Medicare Advantage plan and return to Original Medicare.

Option 2: Return to Original Medicare and Consider a Medicare Supplement
If you currently have Medicare Advantage, Fall Open Enrollment gives you the opportunity to return to Original Medicare.
Original Medicare includes:
- Part A — Hospital Insurance
- Part B — Medical Insurance
You may also choose to add:
- A Part D prescription drug plan
- A Medicare Supplement Insurance policy, also called Medigap, to help cover certain out-of-pocket costs left by Original Medicare.
Important Medigap Consideration
Medicare Fall Open Enrollment is not the same thing as Medigap Open Enrollment.
Your six-month Medigap Open Enrollment Period generally begins when you are both:
- Age 65 or older, and
- Enrolled in Medicare Part B.
Outside of that period, depending on your situation and state, an insurance company may be able to:
- Ask health questions.
- Use medical underwriting.
- Charge a different premium.
- Decline your application.
There are also situations where you may qualify for guaranteed-issue rights, and some states provide additional Medigap protections.
Important: If you're considering leaving Medicare Advantage for Original Medicare and want a Medicare Supplement, it's important to understand whether you qualify for the Medigap policy before making your final coverage decision.

Option 3: Join or Change a Medicare Part D Prescription Drug Plan
If you have Original Medicare, you can purchase a separate Medicare Part D prescription drug plan.
Part D:
- Helps pay for covered prescription medications.
- Is offered by Medicare-approved private insurance companies.
- Has its own formulary, or list of covered medications.
- Can have different premiums, deductibles, copays and pharmacy networks depending on the plan.
During Fall Open Enrollment, people with Original Medicare can:
- Join a Part D plan.
- Switch from one Part D plan to another.
- Drop Part D coverage.
Be Careful About Going Without Drug Coverage
You may owe a Part D late enrollment penalty if you go 63 consecutive days or longer without Medicare drug coverage or other creditable prescription drug coverage after you're eligible.
The penalty is generally added to your monthly Part D premium for as long as you have Medicare drug coverage.

The Takeaway
Medicare plans can change every year — and your health care needs can change too.
Taking a little time during Fall Open Enrollment to review your coverage can help you avoid surprises in the coming year.
Before making a decision, consider reviewing:
- Your doctors and hospitals
- Your prescription medications
- Your pharmacies
- Your premiums and out-of-pocket costs
- Your plan benefits
- Your travel and health care needs
You don't necessarily need to change your Medicare coverage every year. The goal is simply to make sure the coverage you already have still makes sense for you.
