What Does Medicare Part J Cover? 
Unfortunately , there is no such thing as Medicare Part J. Medicare consists of 4 parts - Part A -LRB- hospital insurance -RRB- , Part B -LRB- medical insurance -RRB- , Part C -LRB- Medicare advantage -RRB- , Part D -LRB- prescription drug coverage -RRB- . In addition to these 4 parts , there are also Medicare supplement programs available for individuals to provide coverage for the gaps in benefits that Original Medicare -LRB- Parts A & B -RRB- do not cover . There used to be a Medicare Supplement Plan J , however , in 2010 , this plan was taken off the market along with plans E , H , and I .
