Because people ask ‘ what is a Medicare Advantage (MA) plan?  MA is another way to get your Medicare Part A and Part B coverage. Sometimes called “Part C” or “MA Plans,” these are offered by Medicare-approved private companies that must follow rules set by Medicare. If you join a Medicare Advantage Plan, you’ll still have Medicare.  But you’ll get most of your Part A and Part B coverage from your Medicare Advantage Plan, not Original Medicare.
