What You Need to Know

Open Enrollment is Oct. 15 to Dec. 7

Medicare Open Enrollment is your opportunity to make changes or enroll in a Medicare Advantage or Prescription Drug Plan. You can use the plan recommendation tool to help you choose your plan with confidence.

If you're satisfied with your current plan and it's available next year, there's nothing you need to do. Your plan will automatically renew.

Medicare Advantage Plans


Aon offers high-quality Medicare Advantage plans with low or zero monthly premiums in many areas. Most Medicare Advantage plans cover both medical and prescription drugs, and many retirees find them to be a great long-term financial choice that helps maximize their health care budget.

You can only enroll in or change a Medicare Advantage plan during Open Enrollment. You must submit your application between October 15 and December 7, and your new plan will start on January 1.

Switching to a New Medicare Advantage plan

If you're currently enrolled in a Medicare Advantage plan and want to switch to a different one, just log in and go to View Plans to see if there's a better fit.

If you decide to switch, simply add the plan to your cart and start the enrollment process.

Changing to a Medicare Supplement Plan

If you switch from Medicare Advantage to a Medicare Supplement plan, you'll need to do it during Open Enrollment, and you'll have to answer health questions on your application (also known as underwriting). There's a possibility you won't be able to get a Medicare Supplement Plan if you don't pass underwriting. However, certain situations, like moving to a different county, may allow you to change to Medicare Supplement without going through underwriting.

Use the plan recommendation tool to compare your Medicare Advantage plan to Medicare Supplement plans. If you decide to switch, add the plan to your cart and go through the application process.

Medicare Advantage plans usually cover medical expenses and prescription drugs, and often come with extra benefits like vision and dental.


Prescription Drug Plans


You can save time by looking for a new plan with the plan recommendation tool. Just log in, then go to View Plans to compare your current Prescription Drug Plan to others. You can see if your medications are covered, find out how much you can save by using mail order, and compare plans side by side. Add your plan to the shopping cart when you're ready to start the enrollment process.

If you want to enroll in or change your Prescription Drug Plan, you must do so during Open Enrollment. You must submit your application between October 15 and December 7, and your new plan will start on January 1.

Keeping your Prescription Drug Plan

To keep your current Prescription Drug Plan, simply do nothing. As long as it's available, your plan will automatically renew.

Depending on what type of Medicare plan you pick, you may need additional coverage for prescription drugs.


Medicare Supplement Plans


Medicare Supplement plans (also called Medigap) help pay for some of the costs Original Medicare doesn't cover, like copays, coinsurance and deductibles. With this option, most people buy two separate plans — a Medicare Supplement plan for medical expenses and a Prescription Drug Plan for medications.

Changing Your Medicare Supplement Plan

If you have a Medicare Supplement plan, you can change plans anytime — you don't have to wait until Open Enrollment. Just keep in mind that when you first got Medicare Supplement, you had a one-time, 6-month window to enroll without health questions (underwriting). If you change your plan after that window, you'll have to answer health questions in most states, and the insurance company can accept or decline your application based on your health.

To avoid becoming uninsured, you can submit an application and end your current coverage only after you've been approved.

Shop for a new Medicare Supplement Plan with our plan recommendation tool. Be sure to check your Prescription Drug Plan to see if it's still the best plan for you, as well. And, it's a good idea to review your Medicare Advantage options to see if that type of plan is a better long-term financial choice for you.

Keeping Your Medicare Supplement Plan

If you like your Medicare Supplement plan and want to keep it, simply do nothing. Your plan will automatically renew.

Medicare Supplement, also known as Medigap, gives you dependable monthly costs and flexibility with the doctors you can see.


Other Important Information


When to Consider a New Plan

If you've moved to a different county or state, if your health needs or finances have changed, or if your plan just isn't working for you, it might be time to find a new plan.

If you've moved, you can log in to update your account information online or call us to find new coverage. Always change your plan through Aon, not the insurance company. If you have a Health Reimbursement Account (HRA), you could lose it if you call the insurance company directly.
