Frequently Asked Questions
Can I switch between Medigap and Medicare Advantage?
You can switch from Medigap to Medicare Advantage anytime during Annual Enrollment (Oct 15 - Dec 7). Switching back to Medigap is much harder—you may face medical underwriting.
What if I develop a serious illness with Medicare Advantage?
You’ll be limited to the MA network and may pay more out-of-pocket up to the $8,850 maximum. You generally cannot switch to Medigap mid-year unless you have a special enrollment situation.
Is Medigap worth it if I’m healthy?
If you’re very healthy and don’t use healthcare often, Medicare Advantage will likely cost less. But consider: Medigap is insurance against future health problems. Once you develop a condition, switching to Medigap becomes difficult.
Do Medigap premiums increase faster than Medicare Advantage?
Medigap premiums increase with age (attained-age) and inflation. MA plan premiums are more stable but benefits can change annually. Long-term, Medigap may cost more in premiums but protect you from high out-of-pocket costs.
Can I have Medigap and Medicare Advantage at the same time?
No. It’s illegal for an insurer to sell you Medigap if you have Medicare Advantage. You must disenroll from MA before Medigap takes effect.
