What Is Medicare Plan H? 
Plan H was a Medicare supplement plan that used to be available for purchase - this plan , along with plans E , I , and J were discontinued in June 2010 when the rules were changed so that prescription coverage could no longer be sold with a Medicare supplement plan -LRB- you now have to buy a separate stand-alone part D prescription drug plan -RRB- . Plan H is similar to plan G today , except plan H did not cover Part B excess charges -LRB- Plans F and G do -RRB- . Medicare supplement plans are guaranteed renewable so if you had one before they were pulled from the market , you can still keep it.If you want to secure new coverage that offers more comprehensive benefits , you may want to look into a plan F -LRB- and add a Part D plan for prescription benefits -RRB- .
