Medicare always did cover the Inogen if that was the arrangement you wanted from your supplier. Most DME companies have them and any company that supplier O2 equipment will have them. Check the yellow pages.
as far as O jave been able to determine - the Inogen is only available from Inogen company if you have Medicare....can't specify the POC according to information I received from Lincare
Medicare pays for my portable oxygen as well as my stationary oxygen equipment check with your provider about getting your portable oxygen
check their web site - www.imogen.com or phone (Phone number can only be seen by the question and answer creators) Hope this helps.
