What Is The Difference Between Medicare Advantage And Medigap Insurance? 
Medicare Advantage plans are a privatized form of Medicare . When you enroll in an Advantage plan you are no longer in original Medicare . Your claims and care are managed by a private insurance carrier . If you are enrolled in original Medicare you should consider buying a Medigap -LRB- Medicare supplement -RRB- plan to cover your deductibles , coinsurance and other out of pocket costs on Medicare approved claims . Once beneficiaries understand the difference in Medicare Advantage and Medigap plans , almost everyone prefers the safety and flexibility of original Medicare and a Medigap plan .
