Understanding Your Options: Medicare Advantage vs. Medigap
What Is Medicare Advantage?

What Is Medigap (Medicare Supplement Insurance)?
Medigap is supplemental insurance that helps cover the "gaps" in Original Medicare, like copayments, coinsurance, and deductibles. It's sold by private insurers and works alongside your Original Medicare.

When Medicare Advantage Might Be Better for You
1. You're Looking for Lower Monthly Costs
Medicare Advantage plans often have low or even $0 premiums. If keeping monthly costs down is a priority, this could be a good fit.
2. You Want Extra Perks
Many Advantage plans throw in extras like dental, vision, gym memberships, and hearing aids—benefits Original Medicare doesn’t cover.
3. You Don’t Travel Much
Medicare Advantage networks are usually local. If you stay close to home for healthcare, this might not be an issue.
When Medigap Might Be the Better Choice
1. You Want Predictable Costs
Even though Medigap plans can have higher monthly premiums, they significantly reduce surprise medical bills. If peace of mind is your priority, this is a win.
2. You Travel Often
Medigap gives you access to any provider in the U.S. that accepts Medicare, perfect for snowbirds or frequent travelers.
3. You Want Long-Term Flexibility
Medigap lets you stick with Original Medicare, which tends to be more stable over time compared to private Advantage plans.
