The chart on this page shows the features of Original Medicare (Parts A and B), Medicare Advantage (Part C), Medicare prescription drug coverage (Part D) and Medicare supplement insurance (Medigap). You can quickly see which parts and plans offer which benefits and how they compare.
Once you master this, you are well on your way to making informed Medicare decisions.
