The rules — and the reality — of switching plans between October 15 and December 7
One of the most common questions during the Medicare Annual Enrollment Period (AEP) is:
“If I change my mind, can I change again?” The short answer: Yes. But there are a few things you should know.
The Basics
- Did you look at your Annual Notice of Change (ANOC) to see what’s changing in 2026?
- Are your doctors, hospitals, and specialists still in your plan’s network?
- Have your prescriptions changed or do you expect new ones next year?
Step 2: Compare Costs for 2026
The Annual Enrollment Period runs from October 15 to December 7.
- During this time, you can switch from Original Medicare to Medicare Advantage (and back).
- You can join, drop, or switch Part D prescription drug plans.
- You can change from one Medicare Advantage plan to another.
How Many Times Can You Switch?
There’s no official limit on how many times you can make changes during AEP. You could
change plans multiple times if you want to.
But here’s the catch: Only your last choice submitted by December 7 counts. That’s the plan that will go into effect on January 1, 2026 .
Why People Switch More Than Once
- Comparing options takes time. You might choose a plan early, then find a better one later.
- Doctor or drug coverage changes. After looking closely, you might realize your doctor isn’t in-network or your medication isn’t covered as well as you thought.
- Costs matter. Sometimes the premiums or copays look good at first glance, but the total yearly cost isn’t the best fit.
Be Careful About Last-Minute Changes
Yes, you can keep switching — but last-minute decisions can cause stress. If paperwork isn’t processed correctly or you miss the December 7 deadline, you could be stuck in the wrong plan
for a year.
Key Takeaway
You can make multiple changes during AEP, but your final choice before December 7 is the one that matters.
The smartest approach is to:
- Review your Annual Notice of Change early.
- Compare your top options carefully.
- Work with your broker to confirm your doctors and prescriptions fit the plan.
That way, you’ll feel confident about your choice — and won’t need to scramble with last-minute switches.
