Is your Medicare plan changing or ending?

Upload the letter you received (an Annual Notice of Change, a plan termination notice, or a drug coverage change) and we will explain what it means, your deadlines, and exactly what to do next.

PDF or photo, max 6 MB. Your letter is used only to explain your situation, and it is stored securely.

This explains your notice and general Medicare rules. It is not insurance advice and not a recommendation of any specific plan. CareRoute does not sell insurance or earn plan commissions. Confirm details with your plan or 1-800-MEDICARE before you enroll.

Which notice did you get?

The tool handles the notices Medicare beneficiaries most often receive:

  • Annual Notice of Change (ANOC). Mailed by late September, it lists next year's changes to your plan's premiums, copays, network, and drug coverage. Your plan is usually not ending, but the details can shift.
  • Plan ending, non-renewal, or leaving your area. Your plan will not be offered to you next year. You must choose new coverage, and you get a special enrollment window and possible Medigap rights.
  • Drug (Part D) formulary change. A medication is being dropped or moved to a higher tier. There are ways to bridge this, including a transition fill.
  • Extra Help / low-income subsidy change. A change to the assistance you get with drug costs.

The Medicare deadlines that matter

Oct 15 to Dec 7

Annual Election Period. Anyone can switch Medicare Advantage or Part D plans for January 1.

Jan 1 to Mar 31

Medicare Advantage Open Enrollment. Switch MA plans once, or return to Original Medicare with a drug plan.

Dec 8 to end of Feb

Special Enrollment Period if your plan is ending or leaving your area, plus possible Medigap rights.

The exact windows that apply depend on your specific notice. Upload it above and we will pin down your dates.

The hard part: which option actually fits you

Understanding the letter is step one. The real work is checking whether your doctors stay in network and your prescriptions stay covered under the plans available to you, and what you would actually pay. That has to be checked plan by plan. CareRoute Decision Support does that research for you and gives you a clear, factual comparison so you can choose with confidence. You make the choice and enroll yourself; we do the legwork.

Frequently asked questions

What does it mean if my Medicare Advantage plan is ending?

It means the insurer will no longer offer that plan to you next year, either because the plan is being discontinued or because it is leaving your county. Your current coverage stops on December 31, so you need to choose new coverage to avoid a gap. Because the plan is ending through no fault of your own, you get a Special Enrollment Period to pick a new plan, and you may also qualify to buy a Medicare Supplement (Medigap) policy without medical questions. Upload your letter above and we will lay out your specific deadlines and options.

What is an Annual Notice of Change (ANOC)?

The Annual Notice of Change is the letter your Medicare Advantage or Part D plan mails every year by late September. It describes what is changing for the coming year: premiums, copays, deductibles, the provider network, and which drugs are covered and at what tier. Your plan is usually not ending, but the costs and benefits can shift enough that it is worth comparing your options during the fall enrollment window. Upload your ANOC and we will summarize exactly what changed.

What deadlines do I have to change my Medicare plan?

The main window is the Annual Election Period, October 15 to December 7, when anyone can switch Medicare Advantage or Part D plans for coverage starting January 1. If you are in a Medicare Advantage plan, there is a second window, January 1 to March 31, to switch plans once or return to Original Medicare. If your plan is ending or leaving your area, you get an additional Special Enrollment Period, which generally runs December 8 through the end of February. The exact dates that apply to you depend on your notice.

Do I get a Special Enrollment Period if my plan is ending?

Yes. When your plan is non-renewing or terminating, Medicare gives you a Special Enrollment Period to enroll in new coverage, typically from December 8 through the end of February. You may also have a guaranteed-issue right to buy a Medicare Supplement (Medigap) policy without answering health questions, usually within 63 days of losing coverage. These rights are easy to miss, so we flag them for you when they apply.

Will my current doctors and prescriptions be covered by a new plan?

That is the most important question, and it has to be checked plan by plan, because each Medicare Advantage and Part D plan has its own provider network and drug list, and both can change from year to year. The free letter check tells you what to investigate. If you want it done for you, CareRoute Decision Support researches whether your specific doctors stay in network and your prescriptions stay covered under the options available to you, then gives you a clear comparison so you can choose with confidence.

Is the Medicare Letter Check free?

Yes. Uploading your notice and getting the plain-language explanation, your deadlines, your rights, and an action checklist is completely free. If you want CareRoute to do the deeper research (verifying your doctors and drugs against each option and comparing your real costs), that is our paid Decision Support service, which is optional.

Does CareRoute sell insurance or earn plan commissions?

No. CareRoute does not sell insurance and does not receive commissions from any plan or insurer. We are an independent healthcare navigation service. You choose your coverage and complete your own enrollment. We help you understand the change and, if you want, research which options fit your actual healthcare needs. That independence means our only job is to give you the clearest, most honest picture.
