Can I change my Medicare plan after open enrollment ends?

Yes, if you qualify for a Special Enrollment Period (SEP) — for example, moving to a new ZIP code, losing employer coverage, qualifying for Extra Help, or your plan ending its contract with Medicare. Medicare Advantage members also get a second window January 1 – March 31 to switch back to Original Medicare or change MA plans once.

Will I have a gap in coverage when I switch?

No, as long as your new plan's effective date is the day after your old plan ends. The old plan is automatically disenrolled when you enroll in a new one — you should never cancel manually.

Can I switch from Medicare Advantage back to Original Medicare in Tennessee or Georgia?

Yes. During AEP (Oct 15 – Dec 7) or the Medicare Advantage Open Enrollment Period (Jan 1 – Mar 31), you can drop your MA plan and return to Original Medicare. You may also want to add a Part D drug plan and a Medigap policy — but Medigap underwriting rules differ in TN and GA, so it's worth a 15-minute call before you switch.

The four windows when you can change

There are only four times Medicare lets you switch plans. Miss them and you're locked in until the next one.

Annual Enrollment Period (AEP)

October 15 – December 7

Change anything — Advantage, Part D, or back to Original Medicare. New plan starts January 1.

Medicare Advantage Open Enrollment (MA-OEP)

January 1 – March 31

If you're already on a Medicare Advantage plan, you can switch to a different MA plan once or drop back to Original Medicare. Doesn't apply to Original Medicare members.

General Enrollment Period

January 1 – March 31

For people who missed their first sign-up for Part B. Coverage starts the month after you enroll.

Special Enrollment Period (SEP)

Triggered by a life event

Moved out of your plan's service area, lost employer coverage, qualified for Medicaid or Extra Help, plan left Medicare, or you live in a long-term care facility. SEPs typically last 2–3 months from the event.

Step 1 — Know what you have today

Before changing anything, pull these out:

Your red, white, and blue Medicare card (or your MyMedicare.gov login).
Your current plan's Annual Notice of Change (ANOC) — mailed every September. It lists what's changing for next year.
A list of your prescriptions (name, dose, how often) and your doctors.

Step 2 — Compare on the right things

Most people pick the plan with the lowest premium. That's almost always the wrong call. Compare in this order:

Are my doctors in-network? Especially specialists in Knoxville, Memphis, Atlanta, or Savannah — networks shrink and grow every year.
Are my drugs on the formulary, and what tier? A $0-premium plan with your insulin on Tier 4 will cost more than a $30 plan with it on Tier 2.
What's the max out-of-pocket? This is the worst-case number for a bad health year.
Then look at the premium.

Step 3 — Enroll the right way

You have three legitimate ways to switch:

Call 1-800-MEDICARE directly.
Use Medicare.gov's Plan Finder and enroll online.
Work with a licensed agent (that's me) — no cost to you, the carrier pays the commission either way.

Never cancel your old plan manually. Enrolling in the new one automatically disenrolls the old one on the right date. Cancelling first creates a gap.

Tennessee & Georgia: the local quirks

Medigap underwriting. Both TN and GA allow medical underwriting outside your initial 6-month Medigap window — meaning a carrier can decline you or charge more. Georgia's new "birthday rule" (since 2024) lets you switch to an equal or lesser Medigap plan within 60 days of your birthday without underwriting. Tennessee does not have one yet.
Rural network gaps. Several MA plans look great on paper but have thin specialist networks in East TN and South GA. Always check your specific providers before switching.
TennCare & Georgia Medicaid coordination. If you're dual-eligible, certain D-SNP plans cover things Original Medicare won't — dental, transportation, OTC allowance. Worth a separate look.

Frequently asked

Can I change my plan after open enrollment ends?

Yes — if you qualify for a Special Enrollment Period. Moving, losing employer coverage, qualifying for Extra Help, or your plan ending its Medicare contract all trigger one.

Will I have a gap in coverage?

No — as long as you enroll in the new plan before the old one ends. The old plan auto-cancels on the correct date.

Can I switch from Medicare Advantage back to Original Medicare?

Yes, during AEP (Oct 15 – Dec 7) or the MA Open Enrollment Period (Jan 1 – Mar 31). You'll likely want to add a Part D plan and a Medigap policy — and that's where TN vs GA underwriting rules matter.

Does it cost anything to use an agent?

No. Carriers pay the same commission whether you enroll online, by phone, or with an agent. You don't pay extra, and the plan price is identical.
