Supplemtal
Supplemental plans helps fill "gaps" in Original Medicare because Medicare does not pay for all health care services or medical supplies. Plan benefits do not change if you pay the monthly premium. Supplem,ental plans allow you to relocate to another state and keep the plan benefits. Part D prescription coverage is not included in a Supplemental plan.
Medigap
Medigap pans help pay some of the remaining health care costs, like yearly Part A deductibles, Coinsurance and Copayments. You pay the monthly premium and depending on your Medigap level, you may pay zero for all health costs and medications.
Cost
Cost plans are only offered in certain counties in Minnesota, generally outside the metro Twin Cities counties. Cost plans have defined networks, clinics and care facilities.
