What is Part C of Medicare?
Medicare Part C is most commonly referred to as Medicare Advantage (MA) plans.
MA plans are offered by private insurance companies and work in place of Original Medicare. You usually pay a lower monthly premium amount for these plans, when compared to Medicare Supplement coverage, but you are subject to co-pays/co-insurance when you see your doctor or receive medical services.
MA plans combine your hospital, doctor and prescription drug (usually) coverage all into one plan so you would be using one card at the hospital, doctors office and pharmacy.
These plans work completely different than a "Medicare Supplement". You must choose one or the other. You get to choose whether you want to receive your care directly from "Original Medicare" Parts A and B and adding an optional Medicare Supplement or from a private insurance company offering a Medicare Advantage plan.
It is very important to know that you can't have Medicare Supplement and a Medicare Advantage plan at the same time. You must choose one or the other.
