Do I Need Medigap If I Have Medicaid? 
No . If you have full Medicaid assistance you no longer need a Medigap Supplement policy . Everything that is not covered by Medicare will be covered by Medicaid . However you should make sure you are on full Medicaid . There are some people who get Medicaid assistance that pays their Medicare Part B Premium and RX assistance but does not pay their Medicare co-pays or deductibles .
