Your deadlines
- Now through February 28, 2027: because your plan is ending, you can choose new coverage until the end of February. Through December 7 you use the Annual Enrollment Period; from December 8 you use a Special Enrollment Period for people whose plan is ending.
- By December 31, 2026 for no gap: choose by December 31 and your new plan starts January 1, 2027. Choose in January and it starts February 1; choose in February and it starts March 1. Until then you'd have Original Medicare without drug coverage.
- Up to March 4, 2027: you have a guaranteed right to buy certain Medigap (Medicare Supplement) policies with no health questions. Apply as early as 60 days before your plan ends and no later than 63 days after it ends on December 31.
If your plan continues in 2027, these special deadlines don't apply; the usual Annual Enrollment Period (October 15–December 7) and Medicare Advantage Open Enrollment Period (January 1–March 31) rules do.
What happens if you do nothing
You won't lose Medicare. If you don't join another plan, you'll have Original Medicare (Part A and Part B) starting January 1, 2027. Original Medicare doesn't include drug coverage, so you'd also need a Part D plan, and it has no yearly limit on what you pay out of pocket unless you add a Medigap policy.
Five steps to take before December 31
- Find your letter. Your plan sent an Annual Notice of Change or a non-renewal notice. Keep it handy.
- List your doctors, hospitals and prescriptions, with the dose of each drug.
- See what's offered in your county. Every Arizona county still has Medicare Advantage plans open to everyone in 2027. Everywhere, you can also choose Original Medicare with a Medigap policy and a Part D plan.
- Talk with a licensed insurance agent. An agent can check your doctors and drugs against each option at no cost to you. Call (602) SENIORS (602-736-4677), TTY 711.
- Enroll by December 31 so your new coverage starts January 1 with no gap. You have until February 28 if you need more time.
How a licensed insurance agent can help
- Compare plans from the companies they work with in your county, side by side, at no cost to you.
- Check whether your doctors, hospital and pharmacy are in each plan's network, and how each plan covers your prescriptions.
- Help you apply for a Medigap policy while your guaranteed right lasts.
- Meet in person, by phone or by video, in English or Spanish.

Will I lose my Medicare?
No. Only your Medicare Advantage plan is ending. If you don't choose a new plan, you'll have Original Medicare (Part A and Part B) on January 1, 2027, but no drug coverage unless you join a Part D plan.
What is the deadline to choose a new plan?
Because your plan is ending, you have until February 28, 2027. Choose by December 31, 2026 and your new plan starts January 1 with no gap. If you choose in January, it starts February 1; in February, March 1.
Can I buy a Medigap policy without health questions?
Yes, for a limited time. When your Medicare Advantage plan leaves your area, you have a guaranteed right to buy certain Medigap policies if you switch to Original Medicare. Apply from 60 days before your plan ends until 63 days after it ends (by March 4, 2027).
Does it cost anything to talk with an agent?
No. Licensed insurance agents are paid by the insurance companies, not by you. You pay the same for a plan whether or not you use an agent.
