I'm just turning 65 and signed up for Medicare with a supplement. I require O2 24/7. My insurance supplement says if Medicare pays, we pay. Let's say I want a POC from Inogen and they except Medicare. So Medicare pays 80% and my supplement pays the other 20%. Now I also need a home concentrator. I would like one I saw with Respironics and they accept Medicare too. So Medicare pays 80% and my supplement pays 20%. My question is: Can you only use Medicare one time per year to get oxygen or would the scenario above work. Could I receive 3 concentrators in a year? I've heard some people on this site say Medicare paid for both their concentrators, and other people say Medicare won't pay for their's. Not even one. And again my insurance agent says if Medicare pays so does your supplement. Can any of you with Medicare experience clarify this for me, ole Hack is mixed up, thanks people
