Frequently Asked
Can I change my mind later?
Yes. AEP (Oct 15 – Dec 7) and OEP (Jan 1 – Mar 31) are the two main windows to switch or drop an MA plan and return to Original Medicare.
Yes — Medicare gives you regular chances to change course.
- Annual Election Period (AEP), Oct 15 – Dec 7: Join, switch, or drop an MA plan. Changes take effect Jan 1.
- MA Open Enrollment Period (OEP), Jan 1 – Mar 31: If you're already in an MA plan, you get one chance to switch to a different MA plan or go back to Original Medicare.
- Special Enrollment Periods (SEPs): Triggered by life events — moving out of a plan's service area, losing coverage, qualifying for Extra Help, etc.
Returning to Original Medicare + TFL is always allowed. Your TFL coverage stays intact regardless of which window you use.
One caveat for those considering a Medigap plan (uncommon for TFL beneficiaries since TFL already wraps Medicare): Medigap doesn't have the same guaranteed-issue protections after the initial 6-month window. Most TFL beneficiaries don't need Medigap at all.

- Can I go back to Original Medicare if I try Medicare Advantage?Yes. During AEP (Oct 15 – Dec 7) or MA OEP (Jan 1 – Mar 31), you can drop your MA plan and return to Original Medicare. TFL stays in place either way.
- I'm turning 65. What should I do first?About 90 days before your 65th birthday, enroll in Medicare Parts A and B through SSA. TRICARE For Life activates automatically once both are effective and DEERS is current.
- Should I choose Medicare Advantage?It's an optional consideration. A veteran-focused MA plan can lower your Part B premium and add dental/vision/hearing — while TFL continues to wrap around it.
