It’s finally fall! For many people, that means football, foliage, and delicious pumpkin-flavored treats. For Medicare recipients, fall also signals a slightly-less-fun (but equally important) event: the annual Medicare Open Enrollment Period (OEP). Open Enrollment occurs every year from October 15th to December 7th. During Open Enrollment, anyone with Medicare can change their prescription drug plan or Medicare Advantage plan for any reason.

**Please note, as a result of Hurricanes Harvey, Irma, and Maria, the Centers for Medicare & Medicaid Services (CMS) has authorized a special enrollment period for all Medicare beneficiaries and certain individuals seeking health plans offered through the Federal Health Insurance Exchange. This special enrollment allows Medicare beneficiaries affected by these hurricanes to enroll, dis-enroll or switch Medicare Advantage Plan and/or Medicare prescription drug coverage. It is available at the start of the incident period and runs through the end of the calendar year (December 31st, 2017). Individuals may contact 1-800-MEDICARE to request enrollment using this special enrollment opportunity.

You may be thinking, “But I already chose my Medicare plan! Why change plans and go through all that again?” The answer is simple: to make sure your coverage is still the best fit for your needs. Insurance companies can make yearly adjustments to Medicare plans, potentially increasing your out-of-pocket costs (these changes are outlined in your Annual Notice of Change–more on this below). Given these yearly changes, it is a good idea to re-evaluate your current Medicare plan each year, and compare it against other available options. Switching to a different Medicare Advantage or Part D plan could potentially save you hundreds of dollars a year.

Not sure where to start? Check your mailbox

Not sure where to start when it comes to evaluating your coverage? It’s actually as easy as looking in your mailbox. Starting in October, insurance companies will start flooding your mailbox with marketing materials about their plans. The Centers for Medicare and Medicaid Services (CMS) will also send you mail alerting you to coverage changes you may need to make. So, how do you know which mail to open and which to recycle?

To start, follow our guide to the most important mailers below:

  • Annual Notice of Change/Evidence of Coverage (ANOC/EOC): You’ll receive this if you have a Medicare Advantage plan or a Medicare Part D plan. Your plan has to mail it out to you by September 30, so it should be in your mailbox in early October. If you don’t receive it by the second week in October, then call your plan and ask for it. Or look for it online and download a copy. The ANOC/EOC is a BIG packet (it’s easy to get overwhelmed) but resist the urge to stash it in a drawer unopened. You will need the Evidence of Coverage (EOC) part because it lists specific details about when your plan will cover costs, which you will need if you have to file an appeal. The ANOC part lets you know what aspects of your plan will change from 2017 to 2018; remember, insurance companies can make yearly changes to Medicare plans that might increase your out-of-pocket costs. The ANOC/EOC is the only mailer plans are required  to send out in order to alert you to these yearly plan changes. Whether the changes are major or minor, you need to figure out what impact they will have on you.
  • Medicare & You Handbook: The Centers for Medicare and Medicaid Services (CMS) mails this handbook out in late September. If you don’t receive one by the second week in October, call 1-800-Medicare to get another copy with your state’s specific plan information, or go to to view the general information online. This handbook contains lots of useful information about when Medicare covers certain services, including preventive care, medical equipment and supplies, and much more.
  • Additional mail from the Centers for Medicare and Social Security:
    • If your current plan will no longer be available in 2018, CMS will mail you a letter saying you need to pick a new plan. In addition, your insurance company might send you a letter offering to move you into a different plan to replace the old one. No matter what you decide, make sure you enroll in your new plan by the end of the Open Enrollment period (Dec. 7).
    • CMS will also send you a letter if your current plan received a low star rating for at least three years in a row. 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 the Open Enrollment period to switch to a higher rated plan.
    • Do you qualify for Extra Help to help pay some of the costs of your Part D prescription drug plan? You may receive a letter from CMS saying that you’ll be put in a different plan in 2018; this is known as “reassignment.” Additionally, some people with Extra Help receive letters because they need to submit income information to stay in the program; this is known as “redetermination”.
  • Going paperless. If all this paper mail becomes overwhelming, you can take steps to go paperless. Create a account to start receiving all notices via email. Then, call your plan to learn about their paperless options. You can find their customer service phone number on your insurance card.
