Frequently Asked Questions
Is there a fee to switch Medicare plans?
No. Enrollment assistance from an independent Medicare advisor is provided at no cost to you. Insurance companies compensate independent advisors when you enroll. Your premium is exactly the same whether you use an advisor or enroll on your own.
Can I switch Medicare plans anytime?
No. You must qualify for an enrollment period. The most common is the Annual Enrollment Period (October 15 – December 7), but Special Enrollment Periods may apply in certain situations.
Will my prescriptions automatically transfer when I switch?
No. You should verify that your medications are covered under the new plan’s Part D formulary before switching. Pharmacies can assist, but coverage is not automatic and formularies differ by plan.
Can I switch Medicare plans more than once per year?
Generally no, unless you qualify for a Special Enrollment Period. During the MA Open Enrollment (January 1 – March 31), you can make one additional change if you’re already in an Advantage plan.
What if I’m turning 65 and haven’t enrolled yet?
If you’re new to Medicare, plan-switching rules don’t apply. You’ll choose your first plan during your Initial Enrollment Period. This is also when your Medigap guaranteed-issue rights are strongest.
What is required to switch from Medicare Advantage to a Medicare Supplement plan?
Outside of guaranteed-issue situations, switching from Medicare Advantage to a Medicare Supplement typically requires passing medical underwriting. The carrier can ask health questions, charge higher premiums, or deny coverage based on your health history. This is why the initial enrollment decision at 65 carries the most weight.
