What Is Medicare Advantage Open Enrollment? Medicare Advantage Open Enrollment is a period that runs annually from January 1 to March 31 and allows beneficiaries to adjust their coverage to better meet their healthcare needs.

Unlike the Annual Enrollment Period, which runs from October 15 to December 7 and is open to anyone eligible for Medicare, this window focuses solely on those who want to make changes to an existing Medicare Advantage plan.

During this time, you can:

Switch to another Medicare Advantage plan if your current plan no longer meets your needs. Return to Original Medicare and optionally add a standalone Part D plan for prescription drug coverage. It’s important to note that you cannot join a Medicare Advantage plan for the first time during this period — that opportunity is reserved for other enrollment periods.

Who Can Use the Medicare Advantage Open Enrollment Period? Beneficiaries who meet certain criteria can take advantage of this time to make adjustments to their coverage.

Here’s who qualifies to use the Medicare Advantage Open Enrollment Period:

Currently enrolled in a Medicare Advantage Plan: To participate in OEP, you must already be enrolled in a Medicare Advantage plan. This period is not for individuals with Original Medicare or those looking to join Medicare Advantage for the first time. Instead, it’s a chance for current beneficiaries to modify their coverage or switch to a different plan. Age and residency requirements: As with general Medicare eligibility, you must be a U.S. citizen or legal permanent resident living within the service area of your Medicare Advantage plan. This ensures you remain eligible to maintain or change your plan within the boundaries of its coverage. Preexisting conditions are not a barrier: Unlike some private health insurance options, Medicare Advantage plans cannot deny you the ability to make changes during OEP based on preexisting conditions. This inclusivity makes it easier for beneficiaries to adjust their coverage as health needs evolve. Special circumstances during the Open Enrollment Period: If your current Medicare Advantage plan no longer fits your healthcare needs—due to changes in benefits, costs, or provider networks—OEP allows you to explore other Medicare Advantage options. Alternatively, you can return to Original Medicare and consider enrolling in a standalone Part D plan for prescription drug coverage.

Confirm that your current plan still meets your needs, particularly regarding costs, provider networks, and covered services

Eligibility Misconceptions During Medicare Advantage Open Enrollment Clearing up these misconceptions can help you make the most of this period.

Misconception 1: You Can Enroll in Medicare Advantage for the First Time During OEP One of the most frequent misconceptions is that OEP allows you to join Medicare Advantage for the first time. This is not true.

OEP is specifically for individuals already enrolled in a Medicare Advantage plan. If you’re interested in joining Medicare Advantage for the first time, you’ll need to do so during the Annual Election Period (October 15 – December 7) or have a Special Enrollment Period.

Misconception 2: You Can Switch from Original Medicare to Medicare Advantage Unlike the fall Annual Enrollment Period, OEP does not allow beneficiaries with Original Medicare to switch to a Medicare Advantage plan.

It only permits changes for those who are already enrolled in Medicare Advantage.

Misconception 3: You Can Make Unlimited Changes During OEP While OEP gives you the flexibility to adjust your coverage, you’re limited to making one change during this period.

For example, you can switch to another Medicare Advantage plan or return to Original Medicare, but you cannot repeatedly switch plans.

Misconception 4: Eligibility Is Affected by Preexisting Conditions Medicare Advantage plans cannot deny you the opportunity to make changes during OEP based on preexisting conditions.

Misconception 5: Missing the December 7 Deadline Means You Have No Options While it’s true that OEP cannot be used to join Medicare Advantage after December 7, those already enrolled still have the option to modify their plans during OEP.

Additionally, Special Enrollment Periods (SEPs) are available for those who experience qualifying life events, such as moving out of a plan’s service area.

Steps To Verify Your Eligibility for Medicare Advantage OEP Here’s how you can verify your eligibility step by step:

Step 1: Confirm Your Current Plan Enrollment To participate in OEP, you must already be enrolled in a Medicare Advantage plan. This period does not allow you to switch from Original Medicare to Medicare Advantage for the first time.

Are you currently enrolled in a Medicare Advantage plan? Check to be sure your insurance is active. Step 2: Understand Timing Requirements The Medicare Advantage OEP runs annually from January 1 to March 31, and changes made during this time take effect the first day of the following month.

Step 3: Understand Special Enrollment Period Exceptions If you’re unsure about OEP eligibility, check if you qualify for a Special Enrollment Period (SEP) due to specific life events.

Have you experienced a qualifying event? Examples include moving out of your plan’s area, losing other health coverage, or changes in Medicaid status. Each SEP has a certain number of days where you can make plan changes, be sure to put these dates on your calendar when you have a life event.
