Frequently Asked
Do I need Medigap (Medicare Supplement)?
No. TFL already serves the role Medigap is designed to play. Adding Medigap would be paying for coverage you already have.
No. TFL is your supplement.
Medigap (Medicare Supplement Insurance) is sold by private insurers to fill the gaps in Original Medicare — deductibles, coinsurance, copays. Those are the exact gaps TFL already wraps around.
Buying Medigap on top of TFL means:
- Paying a second monthly premium for redundant coverage.
- Coordination of benefits gets murky with three payers (Medicare, Medigap, TFL).
- No additional benefits in 99% of scenarios.
The decision tree is simple:
- Stay on Original Medicare + TFL — no supplement needed.
- Or switch to a Medicare Advantage plan — TFL becomes secondary to the MA plan; still no supplement needed.
Either path, Medigap is unnecessary for TFL beneficiaries.

FAQs
- 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.
- 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.
- What's the difference between TFL and Medicare Advantage?TFL is a wraparound secondary to Medicare. Medicare Advantage replaces how Original Medicare delivers benefits. They're not mutually exclusive — TFL stays active under MA.
