Medicare Supplement (Medigap) plans are “supplemental” policies offered by private insurers that you can add to your Original Medicare. Since Parts A and B still leave you with 20% to pay out-of-pocket, it’s important to have insurance that can help with the leftover decuctubles, copays, and coinsurance. Any Florida or Texas senior who wants or needs help filling the “gaps” in coverage in Original Medicare could benefit from a Medicare Supplement plan.
