The Medicare Annual Enrollment Period is an important window of opportunity. Medicare beneficiaries can take advantage of this enrollment window each year in the fall.

If you’re currently enrolled in either a Medicare Advantage or Part D drug plan; you’ll be able to make necessary changes to get the benefits you need at the costs you can afford.

We’re about to break it down to help you understand why this annual enrollment window is so important.

How the Medicare Annual Enrollment Period Works

It’s easy to confuse the Medicare Annual Enrollment Period with the open enrollment periods. They do have some things in common. But their dates are completely different, and they vary in the types of changes you are allowed to make to your health care plan.

Here’s what you can expect from the Annual Enrollment Period:

  • You can switch from Original Medicare to Medicare Advantage, or from Medicare Advantage back to Original Medicare
  • You can enroll in, change, or cancel your current Medicare Part D prescription drug plan

Medicare beneficiaries can take advantage of the Medicare Annual Enrollment Period between October 15th and December 7th each year. Both Medicare Advantage & Part D plans are guaranteed to change each year. It’s important to stay on top of what your plan offers – as well as its total costs. Your new plan will go into effect on January 1st of the following year.

Medicare Annual Enrollment Period

The Open Enrollment Period is a little more complex. There are two different types of OEPs:

  1. The Medicare Advantage Open Enrollment Period – You can make changes to your Medicare Advantage plan during the Medicare Advantage OEP if and only if you are already enrolled in Medicare Advantage
  2. Medicare Supplement Open Enrollment Period – If you have Original Medicare, you can shop around between different Medigap plans and you have your whole six-month open enrollment period to settle on a plan. Another benefit of enrolling during this window is that your plan will be guaranteed issue. Meaning you won’t have to prove you’re in good health in order to be given coverage at a fair premium

Here’s What You Can Do During the Annual Enrollment Period

Are you interested in trying out Medicare Advantage for the first time? Do you miss Original Medicare, and want to switch back? What about your prescription drug plan? Does your formulary cover all of the prescriptions you need at a decent price? If you’ve been contemplating any of these questions lately, then you want to take advantage of the AEP as soon as you can.

Switching Between Original Medicare and Medicare Advantage

If you have a Medicare Advantage plan and would like to go back to Original Medicare, you can do that during the AEP. Likewise, if you have Original Medicare but want to switch to Medicare Advantage, you can do that during this window of opportunity, too. If you switch back to Original Medicare you can then enroll in a Medicare Supplement plan at any time.

Change Your Prescription Drug Plan

Your drug plan’s formulary (the drugs which you can purchase at a subsidized discount) and the prices you pay are likely to change on an annual basis. If you have Original Medicare and notice inconvenient changes to your Medicare Part D prescription drug plan, you can shop around and choose a different plan. You can do the same if you have Medicare Advantage and a separate prescription drug plan.

You can also enroll in Medicare Part D if you are switching from Medicare Advantage to Original Medicare, or just cancel your Part D prescription drug coverage entirely, which you’ll likely end up having to do if you switch from Original Medicare to Medicare Advantage.

Here’s Why You Should Review Your Healthcare Coverage Before Each Annual Enrollment Period

We touched on it a little bit so far, but the reality is that your healthcare plan will change on an annual basis. Sometimes it’s simply a modest premium increase. Sometimes your formulary for your prescription drug program may not cover the life-saving drugs you need anymore. You might even lose access to the doctors and health care providers you need most.

Changes in Medical Costs

Regardless of which type of Medicare plan you have, your premiums are likely to increase each year. This is tied to both the cost of medical care for the average beneficiary, as well as inflation rates.

This is true for Medicare Advantage, a Medicare Supplement, and even Medicare Parts A and B. For your private plans like Medicare Advantage, you may also have changes in your coinsurance and copayment costs.

Changes in Medication and Provider Access

Private drug plans have the ability to change their formulary every year. The formulary is a list of drugs that are covered by your plan, as well as the cost that you pay for those prescriptions.

If you have Medicare Advantage, certain doctors and facilities may leave or be eliminated from your provider network.

Conversely, if you have Original Medicare, providers and facilities may choose not to accept Medicare assignment anymore, forcing you to either find care elsewhere or pay out-of-pocket.

Benefits, Ratings, and Travel

Your benefits could change or become more expensive from one year to the next. This is more common with private plans, but those plans can never offer you less than the benefits of Original Medicare without violating the law.

Furthermore, if your plan receives a low rating from its customers, you may no longer feel confident paying for such a plan.

Lastly, how often you travel will greatly affect what sort of plan you want. If you are a snowbird or otherwise travel frequently, you probably aren’t going to want to purchase an HMO plan with a medical network limited to a small zip code.

PPO plans are better for travelers, or Original Medicare since providers all over the country accept Medicare assignment.

Medicare Annual Enrollment Period Eligibility

You have to be enrolled in Original Medicare (Parts A and B) before you can take advantage of the AEP. Beneficiaries may not be enrolled if they have other qualifying coverage. such as an employer health plan.

If that’s the case, you’ll have to wait for either a Special Enrollment Period or the General Enrollment Period in order to enroll in Original Medicare.

FAQs

What is the Annual Coordinated Enrollment Period?

It’s common for the AEP to go by many different names, sort of like how Medicare Part C and Medicare Advantage are the exact same thing. The Annual Coordinated Enrollment Period is just another way of saying “Annual Enrollment Period” and/or “Annual Election Period”. You may also hear people refer to the AEP as the “Fall Open Enrollment Period”, but in reality, open enrollment periods are separate things that follow different rules.

When does the Medicare Annual Enrollment Period start and end?

It starts on October 15th and ends December 7th every year like clockwork. If you decide to change your health plan, your new plan and benefits will go live on January 1st of the following year.

What if I want to switch from Medicare Advantage to Original Medicare and purchase a Medicare Supplement?

You can enroll in a Medicare Supplement at any point in the year. Unlike Original Medicare, Medigap plans do not come with an annual enrollment window. If you choose to take advantage of the AEP and switch back to Original Medicare, you can enroll in a Medigap plan at that time. However, you’ll have to go through medical underwriting if you’re outside your one-time Medigap Open Enrollment Period. The only exception is if you qualify for a Special Enrollment Period.

Do I have to worry about changes to my Medigap plan during the Medicare Annual Enrollment Period?

Medigap plans are standardized, so your benefits will never change. You may, however, see a rise in your monthly premium. If the increase is too drastic, you can switch plans at any time of the year. You don’t have to wait until the AEP to do so.
