What is Medicare Open Enrollment?

Medicare Open Enrollment is a period when you can make changes to your Medicare coverage. This includes switching plans, adding coverage, or dropping coverage. It's important to understand your options to make the best decision for your healthcare needs.

Key Enrollment Periods:

The AEP runs from October 15 to December 7 each year. During this time, you can switch between Original Medicare and Medicare Advantage, join a Medicare Part D plan, or change your Part D plan.
The OEP is from January 1 to March 31. If you're already enrolled in a Medicare Advantage plan, you can switch to another Medicare Advantage plan or return to Original Medicare.
SEPs are triggered by certain life events like moving, losing other insurance, or qualifying for Extra Help. These periods allow you to make changes outside the standard enrollment periods.
Insider Tip from Dr. Ed
Always review your current plan during the Annual Enrollment Period, even if you're happy with it. Plans can change their premiums, coverage, and provider networks each year.

Urgent Action Needed

Facing a Deadline? Here's What to Do

⏰ Time-sensitive: If you're nearing the end of an enrollment period, it's crucial to act quickly. Missing a deadline can result in penalties or gaps in coverage.

Follow these steps to ensure you're covered:

1
Review your current coverage to determine if it still meets your needs. Consider changes in health, medications, and finances.
2
Compare available plans using the Medicare Plan Finder tool. Look for plans that cover your prescriptions and preferred doctors.
3
Enroll in a new plan before the deadline. You can do this online at Medicare.gov or by calling 1-800-MEDICARE.
Insider Tip from Dr. Ed
If you're switching from Medicare Advantage to Original Medicare, consider enrolling in a Medigap policy to cover additional costs. Be aware that you may face underwriting if you're outside your Medigap open enrollment period.

Annual Enrollment Period

What You Can Do During AEP

The Annual Enrollment Period (AEP) is your opportunity to make changes to your Medicare coverage. Here's what you can do:

1
Switch from Original Medicare to a Medicare Advantage Plan — or vice versa.
2
Join a Medicare Prescription Drug Plan (Part D) if you didn't enroll when first eligible.
3
Switch from one Part D plan to another — find a plan that better suits your medication needs.
4
Drop your Part D coverage completely if you no longer need it.
Insider Tip from Dr. Ed
If you switch from Medicare Advantage to Original Medicare during AEP, consider enrolling in a Medigap policy to cover additional costs. Be aware of potential underwriting if you're outside your Medigap open enrollment period.
🔄

Medicare Advantage Open Enrollment Period

What You Can Do During OEP

The Medicare Advantage Open Enrollment Period (OEP) allows you to make changes if you're already enrolled in a Medicare Advantage plan:

1
Switch to another Medicare Advantage Plan — with or without drug coverage.
2
Drop your Medicare Advantage Plan and return to Original Medicare.
3
Enroll in a standalone Medicare Prescription Drug Plan (Part D) if you return to Original Medicare.
Insider Tip from Dr. Ed
Use the OEP to fine-tune your coverage if your needs have changed. This period is not for adding or dropping Part D coverage if you're not switching from a Medicare Advantage plan.
🔄

Special Enrollment Periods

Qualifying for a Special Enrollment Period

Special Enrollment Periods (SEPs) allow you to make changes outside the standard enrollment periods due to specific life events:

1
Moving — If you move out of your plan's service area or to an area with new plan options.
2
Losing current coverage — Such as losing employer coverage or Medicaid.
3
Qualifying for Extra Help — If you qualify for financial assistance with prescription drug costs.
Insider Tip from Dr. Ed
If you qualify for an SEP, act quickly to avoid gaps in coverage. Contact Medicare or your plan provider to understand your options and deadlines.
