Medicare Open Enrollment Period (OEP)
Each year, Medicare Advantage and Part D prescription drug plans update their offerings. These changes are typically announced in the fall, giving individuals the opportunity to review and adjust their plans to better suit their needs.
Since 2019, Medicare beneficiaries enrolled in Medicare Advantage (Part C) plans can utilize the Medicare Advantage Open Enrollment Period (OEP), which runs from January 1 through March 31 annually. During this time, those already enrolled in a Medicare Advantage plan can make a one-time change to their coverage.
The OEP was reintroduced to address the confusion many beneficiaries faced when selecting Medicare Advantage plans, which led to choices they later regretted. For instance, some individuals did not fully understand that certain plans had networks or that some medications might not be covered under a plan’s formulary. Additionally, changes in network providers or restrictive networks prompted some to reconsider their plan options.
If you're satisfied with your current plan, you don’t need to take any action during the OEP.
What You Can Do During the Medicare Advantage Open Enrollment Period (OEP)
During this time, you can:
- Switch from one Medicare Advantage plan to another
- Change from a Medicare Advantage plan with drug coverage to Original Medicare, with the option to add a Part D prescription drug plan.
- Disenroll from Medicare Advantage and return to Original Medicare, with the option to add a Part D plan.
However, switching from one standalone Part D plan to another is not allowed during the OEP.
Why Consider Re-Evaluating Your Medicare Coverage During Open Enrollment?
Your health needs and financial situation may change over time, making it essential to review your coverage annually. This ensures you have the best protection both medically and financially. Additionally, since Medicare plans can be complex, consulting with a licensed Medicare insurance agent can help you navigate your options.
You can also contact Medicare or visit their official website to get further assistance.
How to Re-Evaluate Your Medicare Coverage During Open Enrollment
Each fall, you’ll receive an Annual Notice of Change (ANOC) or Evidence of Coverage (EOC) from your Medicare plan provider. These documents outline changes to your plan for the upcoming year. Carefully review them and consider how those changes align with your healthcare needs. If your current plan still meets your needs, you won’t need to make any adjustments.
Annual Enrollment Period (AEP) for Original Medicare (Part A and Part B)
The Annual Enrollment Period for Medicare Part A and Part B runs from October 15 to December 7 each year. During this period, you can:
- Enroll in a Medicare Advantage (Part C) plan.
- Switch from Medicare Advantage back to Original Medicare.
- Join, drop, or switch a Part D prescription drug plan.
Any changes made during this time will take effect on January 1 of the following year. Keep in mind that if you enroll in Original Medicare during this period outside your Initial Enrollment Period (IEP), you may be subject to late enrollment penalties.
Medicare Prescription Drug Plans (Part D) Enrollment
You have several opportunities to enroll in or modify your Medicare Part D prescription drug plan:
- During your Initial Enrollment Period (IEP) when you first become eligible for Medicare.
- During the Annual Enrollment Period (AEP), which runs from October 15 to December 7.
- During a Special Enrollment Period (SEP) if you experience a qualifying life event (e.g., moving out of your plan’s service area, losing other drug coverage).
- If you qualify for Extra Help, which assists with the cost of prescription drugs, you may also enroll in a Part D plan.
Medigap (Medicare Supplement) Open Enrollment Period
If you’re 65 or older, your Medigap Open Enrollment Period begins the month you’re enrolled in Medicare Part B. This six-month period allows you to purchase a Medigap policy without facing denial for pre-existing conditions. After this window, you may face higher premiums or denial of coverage based on health conditions.
Some states also offer Medicare SELECT plans, which are Medigap policies that require the use of in-network hospitals and doctors for full benefits.
Options If You Miss the Open Enrollment Period
If you miss the Medicare Advantage OEP, you may still qualify for a Special Enrollment Period (SEP) due to specific circumstances, such as moving or losing other coverage. You may also have the option to enroll in a five-star Medicare Advantage or Part D plan once per calendar year between December 8 and November 30.
Other Medicare Enrollment Periods
Several enrollment periods throughout the year allow you to modify your Medicare coverage, depending on your eligibility and circumstances.
General Medicare Eligibility
To enroll in Medicare, you must generally meet the following requirements:
- Be 65 or older and a U.S. citizen or permanent legal resident who has lived in the U.S. for at least five consecutive years.
- If under 65, qualify based on certain disabilities or diseases, such as End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS).
Initial Enrollment Period (IEP)
Most individuals enroll in Medicare at age 65 during their Initial Enrollment Period, a seven-month window that starts three months before the month you turn 65 and ends three months after. If you are already receiving Social Security benefits at age 65, you will automatically be enrolled in Medicare Parts A and B.
Special Enrollment Period (SEP)
You may qualify for a SEP if you delay enrolling in Medicare Part B because you or your spouse have employer-sponsored group health coverage. This SEP allows you to sign up for Part B without penalties when your employer coverage ends. Other SEPs apply to those with Medicaid or those who qualify for Extra Help with prescription drug costs.
General Enrollment Period (GEP)
If you miss your IEP, you can enroll in Medicare Part A and/or Part B during the General Enrollment Period, which runs from January 1 through March 31 each year. Coverage will begin on July 1, but late enrollment penalties may apply.
