Is Medigap The Same As Supplemental Insurance? 
Yes . When you hear the term Medicare Supplement insurance , it is the same as Medigap . If you hear the interchangeable terms -LRB- Medicare Supplement insurance or Medigap Plan -RRB- it is referring to private health insurance designed to supplement Original Medicare Part A and Part B . In other words , it helps pay some of the costs that Part A and Part B does n't cover -- copays , coinsurance , and deductibles . Thank you for reading my response . Please let me know if I can be of further assistance .
