Seems to me if Whoopi could afford the rental of the designated machine she would have - and she is loaded. Sounds like another type was offered that would be covered. Her contributions to her insurance likely would have not paid for her ordeal. Her choice was to stay in the hospital and use the machine, which was covered.
Loved how Mc/mememe said Aidy impersonates her on SNL (btw, once), and Aidy replies I did. LOL
