Your Complete Guide to Medicare Open Enrollment
What is Open Enrollment?
The Medicare Open Enrollment Period is an annual period of time (October 15 through December 7) when current Medicare users can choose to re-evaluate part of their Medicare coverage (their Medicare Advantage and/or Part D plan) and compare it against all the other plans on the market. After re-evaluating, if you find a plan that is a better fit for your needs, you can then switch to, drop or add a Medicare Advantage or Part D plan. Medicare Advantage is also known as a “Part C” plan.
You cannot use Open Enrollment to enroll in Part A and/or Part B for the first time. For more information on all of the parts of Medicare, and when you can enroll in them, visit our Medicare coverage map.
Still confused about Open Enrollment? Try taking our Medicare Questionnaire assessment, which can connect you to free professional advice about Medicare from a licensed benefits advisor (who abides by our Standards of Excellence).
What you can do during the Open Enrollment Period (OEP):
- Anyone who has (or is signing up for) Medicare Parts A or B can join or drop a Part D prescription drug plan.
- Anyone with Original Medicare (Parts A & B) can switch to a Medicare Advantage plan.
- Anyone with Medicare Advantage can drop it and switch back to just Original Medicare (Parts A & B).
- Anyone with Medicare Advantage can switch to a new Medicare Advantage plan.
- Anyone with a Part D prescription drug plan can switch to a new Part D prescription drug plan.
When is Open Enrollment?
Open Enrollment is from October 15th through December 7th every year. If you use the Open Enrollment period to choose a new Medicare Advantage or Part D plan, that new coverage will begin on January 1.

Why should I consider re-evaluating my current Medicare coverage during Open Enrollment?
Unfortunately, choosing health insurance is no longer a one-time decision for most Medicare beneficiaries. Each year, insurance companies can make changes to Medicare plans that can impact how much you pay out-of-pocket—like the monthly premiums, deductibles, drug costs, and provider or pharmacy “networks.” A network is a list of doctors, hospitals, or pharmacies that negotiate prices with insurance companies. They can also make changes to your plan’s “formulary” (list of covered drugs). Given these yearly changes, it is a good idea to re-evaluate your current Medicare plan each year to make sure it still meets your needs. Below are some additional benefits of re-evaluating your coverage during Open Enrollment:
- You can switch to better prescription drug coverage. Using Open Enrollment to switch your drug coverage—or add drug coverage for the first time—can make crucial medications that you need less expensive. It can also ensure that your drug plan still covers the drugs you need (as your prescriptions may not be included on your plan’s formulary for next year).
- You can save money and keep your doctor in-network. Switching your Medicare Advantage or Part D plan can potentially save you hundreds of dollars a year—especially if your current plan’s out-of-pocket costs will increase next year. Research shows that the average consumer can save $300 or more annually if they review their Part D coverage. One way to lower your medical costs is to check that your current doctors, hospital, and pharmacy are “in-network” with whatever Medicare Advantage or Part D plan you choose. If your insurance company has changed your plan’s provider or pharmacy network for next year (and your doctor or other resources will no longer be included), you can use Open Enrollment to switch to a plan that will include your current doctors, hospital and/or pharmacy in-network, thereby lowering your medical costs.
- You can find a higher quality plan. Finally, check the quality of your plan using the Medicare 5-star ratings system. Plans with a 5-star rating are considered high quality and those with fewer than 3 stars are considered poor quality. If your current plan is ranked as less than a 3, consider using Open Enrollment to switch to a higher rated plan.

Next Steps: How do I re-evaluate my current Medicare coverage during Open Enrollment?
Interested in re-evaluating and/or switching your current Medicare coverage? We recommend one of the three options below:
- Take our quick Medicare Questionnaire. It can connect you to free professional counseling from a licensed benefits advisor at Aon Retiree Health Exchange (our trusted partner who abides by the NCOA Standards of Excellence).
- Use the plan finder tool on Medicare.gov. This is the official U.S. government site for Medicare.
- Contact your local SHIP (State Health Insurance Assistance Program). SHIPs provide federally-funded Medicare counseling through a trained staff member or volunteer.
When you have chosen a plan that’s best for your situation, you’ll need to provide your Medicare number and the date your Part A and/or Part B coverage started. This information is on your Medicare card. In general, you need to be careful about when you give out your personal Medicare information (see “5 Steps for Avoiding Medicare Scams“), but this is a situation when licensed advisors in a trusted setting can help you make a beneficial change.
