I'm confused about when I can change my Medicare plan. Can you clarify the different enrollment periods for me?

Ann Sanfelippo · Accepted Answer

There are several Medicare enrollment periods, each with a different purpose. Your Initial Enrollment Period (IEP) is when you first become eligible for Medicare, starting 3 months before your 65th birthday month, including your birthday month, and ending 3 months after. The Annual Enrollment Period (AEP) runs October 15 through December 7 each year and allows you to change Medicare Advantage or Part D plans. The Medicare Advantage Open Enrollment Period (OEP) runs January 1 through March 31 and allows people already enrolled in a Medicare Advantage plan to make one plan change or return to Original Medicare. You may also qualify for a Special Enrollment Period (SEP) if you experience certain life events, such as moving, losing other coverage, or becoming eligible for Medicaid.

It's Pamela Fugitt-Hetrick, and a lot of people are confused about when they can change their Medicare plan. The reason it's confusing is it depends on what Medicare plan you're talking about.

Medicare from the federal government will just give you a notice every year as to what, if anything, has changed and the price of that for you for the next year.

But then behind that we have Medicare supplement and drug plans, or Medicare Advantage plans, and the rules for these are different. So look at your ID cards. If it says Medicare supplement, regardless of the company, if you live in the state of California, at least, we have what's called the birthday rule. You have 60 days from your birthday to take a look at that plan and shop it with other carriers. Maybe you can get the same coverage with another carrier for less money. Maybe you're starting to get priced out and you want to consider coverage that has maybe a deductible or some features that will lower the premium cost for you. So again, Medicare supplement, these are the plans that have the single letter name F, G, and N. Those are the ones you can shop around your birthday.

Prescription drug plans: October 15th through December 7th every year. Take a look at the changes to your plan, if your plan is even continued, and make sure you elect the best plan for you for the following year.

Medicare Advantage plans, these have names like Kaiser Senior Complete, Alignment Health Plan. They're HMOs, PPOs. These plans say Medicare Advantage across your card. And these plans also use the October 15th through December 7th. Do you have to do anything? Technically, no. Should you? Yes, because oftentimes you'll find that these plans have changed. And if you don't elect, take a look, you might not like the change. And after December 7th, it's too late in many cases.

So if you have any questions and you're in the state of California, you know how to find me. Thanks.

It can definitely be confusing. Medicare has several enrollment periods, each with different rules:

• Annual Enrollment Period (AEP): October 15–December 7. You can join, switch, or drop a Medicare Advantage or Part D prescription drug plan, with changes effective January 1.

• Medicare Advantage Open Enrollment Period: January 1–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 (with or without a Part D plan, if eligible).

• Special Enrollment Periods (SEPs): Available in certain situations, such as moving, losing other creditable coverage, qualifying for Extra Help, or other qualifying life events.

The enrollment period available to you depends on your current coverage and individual circumstances. If you're unsure which one applies, a licensed Medicare agent can help you review your options.

Sandra Teel · Answer

I understand your confusion. Different Medicare plans have different times you can make changes.
Most people have a Medicare advantage plan ( HMO or PPO ). Advantage plans have an annual open enrollment period starting Oct 15-Dec 7 each year.  This is when you can make changes to another Advantage Plan, drop an Advantage Plan or change your prescription drug plan. Prescription drug plans fall under the Advantage Plan umbrella.

If you have a Medicare supplement, some states have rules that you can "shop rates" with different companies each year during your birthday.  To find out your state's rules, give me a call.

There are some special election periods for people who are on Medicaid through their state, for some Chronic conditions, if you move out of your area or if you become institutionalized in a care facility.

Of course, each situation is different, so give me a call and we can discuss what might apply to you.

Adriane Williams · Answer

Typically Annual Enrollment period is October 15 to Dec 7th. If you have a life event, qualify for Medicaid, or move you may qualify for a plan change now.

Kristina Guerry · Answer

You can change your Medicare plan at any time throughout the year. You will need to be able to pass the underwriting process. 

There are a series of verbal health questions, once that is completed, we wait to receive an answer from the new insurance company.

There are no enrollment periods once you are already on Medicare, unless you live in a special state that has a birthday rule, anniversary rule, or open enrollment year round.

Mel Stevens · Answer

Enrollment periods can be confusing and the rules are different depending on whether you are enrolling into original Medicare, Medicare supplement, Prescription drug plan or a Medicare Advantage plan. I would suggest contacting a local Medicare specialist to discuss the details.

Ok if you are on a supplement, you do not have an enrollment period, but if you are on Medicare Advantage, you have certain times of the year that you can change to different plans.
