There are two types of Medicare plans, and the way that they are accepted by insurance companies is very different. The first option is Original Medicare with a Medigap plan. On these plans, you do not have a network, so you can go to any doctor or hospital (around 97% of providers in the US accept Medicare). The second option is Medicare Advantage. On these plans, you have a network, so some providers will not accept your plan if you are not in the network or if they don’t accept Medicare Advantage at all.
