What is the Medicare Annual Enrollment Period?
The Medicare Annual Enrollment Period, often called Open Enrollment, is a specific window of time each year when you can make changes to your Medicare coverage. This period runs from October 15 to December 7. Any changes you make will take effect on January 1 of the following year. It is important not to confuse this with your Initial Enrollment Period (IEP), which is the seven-month window when you first become eligible for Medicare around your 65th birthday. It's also distinct from the Medicare Advantage Open Enrollment Period (January 1 to March 31), which only allows someone already in a Medicare Advantage plan to make a single change.
The purpose of the Annual Enrollment Period is to give everyone on Medicare a chance to review their options and switch plans if needed. Insurance companies can, and often do, change their plans every year. These changes can include monthly premiums, copays and coinsurance, the list of covered prescription drugs (the formulary), and the network of doctors and hospitals. Simply assuming the plan that worked well for you this year will work just as well next year can lead to unexpected costs and coverage gaps. This period empowers you to react to those changes and select a plan that better suits your needs for the upcoming year.
Key Actions You Can Take During Open Enrollment
During the October 15 to December 7 Open Enrollment period, you have the flexibility to make several important changes to your Medicare coverage. This is your main opportunity to adjust your plan based on shifts in your health or finances. You can:
1. Switch from Original Medicare (Part A and Part B) to a Medicare Advantage Plan (Part C). 2. Switch from a Medicare Advantage plan back to Original Medicare. If you do this, you can also apply for a standalone Medicare Part D prescription drug plan and, if you can pass medical underwriting, a Medicare Supplement (Medigap) policy. 3. Change from one Medicare Advantage plan to another. This could be a plan from the same insurance carrier or a completely different one. 4. Change from one standalone Part D prescription drug plan to another. 5. Enroll in a Part D prescription drug plan if you didn’t when you were first eligible and you are currently on Original Medicare. Be aware that if you do this and don't have other creditable drug coverage, you may have to pay a late enrollment penalty.
All of these choices are on the table every single year during this period. It's why we at BenefitsCompass encourage all our clients, from Cleveland to Akron and all the towns in between, to treat this as an annual healthcare check-up for their insurance plan.
Why You Must Review Your Coverage Every Year
Sticking with your current plan without reviewing it is one of the biggest risks a Medicare beneficiary can take. Insurance plans are not static; they are annual contracts that can change significantly from one year to the next. The plan that was a perfect fit for you last year might become a poor choice due to these adjustments. For example, let's consider a 68-year-old retired factory worker in Akron whose doctors are all with Summa Health. His current Medicare Advantage PPO plan covers them. However, during the next Open Enrollment, he must verify that Summa Health is still a preferred provider in that plan's network for the upcoming year. Networks can shrink or change.
Furthermore, prescription drug coverage is a major variable. The list of covered drugs, known as the formulary, is updated annually. A medication you take for a chronic condition might be removed from the formulary, or it could be moved to a more expensive cost-sharing tier. Your monthly premium is just one piece of the puzzle. A plan with a zero-dollar premium might have a high maximum out-of-pocket limit or high copays for services you use frequently, like physical therapy or specialist visits. An annual review allows you to catch these changes before they become expensive problems in January.

How to Prepare for Your Annual Plan Review
Being prepared makes the Open Enrollment process much smoother and more effective. Before October 15, it's a good idea to gather a few key pieces of information so you can accurately compare your options. Think of it as assembling your personal healthcare profile. Here’s a simple checklist of what you'll need:
1. **Your Annual Notice of Change (ANOC):** This document is the most important piece of mail you'll receive from your current plan. It arrives in September and outlines every single change to your plan for the upcoming year, comparing current costs and benefits to the new ones. Do not throw it away.
2. **A Complete List of Your Prescription Drugs:** Write down the exact name of each medication you take, the dosage (e.g., 20mg), and how often you take it. This is critical for checking if your drugs will be covered by a new plan and at what cost.
3. **A List of Your Doctors and Hospitals:** Make a list of all the healthcare providers you want to keep seeing, from your primary care physician to specialists like your cardiologist or oncologist. Include the hospitals and urgent care centers you prefer to use. This information is essential for verifying they are in a new plan's network.
4. **Your Red, White, and Blue Medicare Card:** Keep your Medicare card handy as it contains your Medicare number and your Part A and Part B effective dates.
Having this information ready makes it much easier to evaluate whether your current plan remains a good fit or if another plan available in your part of Ohio would serve you better.
Common Mistakes That Delay or Disrupt Coverage
Many people make preventable mistakes during the Annual Enrollment Period that can lock them into a less-than-ideal plan for a full year. One of the most common is simply doing nothing—assuming your current plan will auto-renew without any negative changes. As we've discussed, plans change, and this assumption can be costly. Another frequent error is choosing a plan based only on the monthly premium. A plan with a low or zero-dollar premium might have a smaller provider network or higher copays for the services you actually use. It's crucial to look at the total potential cost, including deductibles and the maximum out-of-pocket limit.
Forgetting to verify prescription drug coverage is another pitfall. A new plan might not cover a critical medication, or it may require prior authorization or step therapy. Finally, waiting until the last minute is a significant risk. The December 7 deadline is firm. If you miss it, you are generally stuck with your current plan until the next Open Enrollment, with very few exceptions. Trying to enroll on December 6th or 7th can be stressful, and you may not have enough time to properly vet all your options or get help from an agent. We've seen people in Northeast Ohio wait too long, only to realize their preferred doctor is no longer in-network come January, when it's too late to change.
How an Independent Agency Can Help
While you can certainly research plans on your own using Medicare's website or by calling insurance companies directly, the process can be time-consuming. State resources like OSHIIP (the Ohio Senior Health Insurance Information Program) offer valuable, unbiased counseling but don't represent specific plans. As a licensed, independent agency based here in Ohio, we serve a different role. For thousands of families across Northeast Ohio, we provide a structured way to compare the specific plans available in their ZIP code. Our service comes at no direct cost to you; we are compensated by the insurance carriers if you decide to enroll in a plan through us.
We can take the lists you prepared—your doctors, hospitals, and prescriptions—and quickly check them against the networks and formularies of multiple plans from different companies. This helps you see a clearer picture of your potential costs and coverage beyond just the monthly premium. We can help you identify if a plan that looks good on paper actually includes your cardiologist at the Cleveland Clinic or if your cholesterol medication will require a high copay. We are here to provide clarity and answer your specific questions. If you would like personalized assistance in reviewing your options for the upcoming Annual Enrollment Period, please fill out the callback form on this page. An agent will be in touch to help you get started.
Frequently asked questions
What's the difference between Open Enrollment and the Medicare Advantage Open Enrollment Period?
The main Open Enrollment (officially the Annual Enrollment Period) is from October 15 to December 7. During this time, anyone with Medicare can make a wide range of changes. The Medicare Advantage Open Enrollment Period (MA-OEP) runs from January 1 to March 31. This period is only for people who are already enrolled in a Medicare Advantage plan. During the MA-OEP, you can switch to a different Medicare Advantage plan or switch back to Original Medicare (and pick up a Part D plan). You can only make one change during this period.
If I'm happy with my plan, do I still need to do anything?
While you are not required to take any action and your plan will likely auto-renew, it is highly recommended that you review it. Your plan's costs, benefits, provider network, and drug formulary can change each year. Your satisfaction with the plan last year doesn't guarantee it will be the best fit next year. Reading your Annual Notice of Change (ANOC) letter, which arrives in September, is the most important step you can take. It will tell you exactly what's changing for the upcoming year.
Can I enroll in a Medigap plan during Open Enrollment?
This is a common point of confusion. The Annual Enrollment Period (Oct 15 - Dec 7) is for changing Medicare Advantage (Part C) and Medicare Prescription Drug (Part D) plans. It is not a designated enrollment period for Medicare Supplement (Medigap) policies. You can apply for a Medigap plan at any time of year. However, unless you are in your 6-month Medigap Open Enrollment Period (which starts when your Part B is effective) or qualify for a guaranteed issue right, you will likely have to answer health questions and can be denied coverage based on your health history.
What happens if I miss the December 7 deadline?
If you do not make any changes by the December 7 deadline, you will generally be locked into your current plan for the entirety of the next calendar year. Your existing plan will typically renew automatically. There are very few exceptions that would allow you to change plans mid-year, which are known as Special Enrollment Periods (SEPs). These are triggered by specific life events like moving out of your plan's service area or losing employer coverage. This is why it is so important to review your options between October 15 and December 7.
I get health insurance from my former employer. Does this period apply to me?
It depends on the specifics of your retiree coverage. Many employer-sponsored retiree plans have their own separate open enrollment period that may or may not coincide with Medicare's dates. These are often Medicare Advantage group plans. You should receive information directly from your former employer or benefits administrator about your options and deadlines. If you are considering leaving your group coverage for an individual Medicare plan, the Annual Enrollment Period would be the time to do so, but be sure you understand the consequences, as you may not be able to get back into the group plan later.
Is OSHIIP the same as an independent agency like BenefitsCompass?
No, we serve different functions. OSHIIP is a free, government-funded counseling service in Ohio that provides excellent unbiased information and education about Medicare. They do not sell or endorse any specific insurance products. An independent agency like ours also provides guidance at no cost to you, but we are licensed insurance agents appointed with multiple insurance carriers. This allows us to directly help you compare specific plans and enroll in the one you choose. We complement the educational role of OSHIIP by assisting with the practical steps of plan selection and enrollment.
Can I use the Open Enrollment Period to sign up for Medicare Part B for the first time if I missed my initial window?
No, the Annual Enrollment Period is not for initial Part A or Part B enrollment. If you missed your Initial Enrollment Period and do not qualify for a Special Enrollment Period (like from leaving employer coverage), you must wait for the General Enrollment Period. The General Enrollment Period runs from January 1 to March 31 each year. If you enroll during this time, your coverage will begin the first of the month after you sign up. You can sign up for Part B by contacting the Social Security Administration, for example at a local Ohio office like the one in downtown Cleveland.
