Is Medicare Advantage An HMO? 
Medicare Advantage plans can be a an HMO or PPO . However , Medicare Advantage/HMO/PPO mean almost the same thing once you are on Medicare , meaning they are all a Medicare Advantage plan . One of the common statements from people turning 65 is , `` I want a PPO '' , because that is what they knew before they went on Medicare . However , it means something way different now that they are on Medicare . A Medicare Supplement is the only plan that does n't have a network and that gives you the greatest flexibility in deciding who you go see for care .
