The show Big Medicine, does the show pay for people to get the gastric byp surgery for appearing on theshow

I know on the show Big Medicine they say they're waiting on the peoples insurance to accept the surgery but I was thinking that may just be for tv to be more realistic and not be bombarded with millions of people calling the show to get the surgery for free. I'm wondering if the show actually pays for the surgery for your participation on the show and airing your story. Just like how people say they don't have money on reality shows and are struggling but you know they get a check every week from the show and from all the reruns which sometimes come on multiple times everyday. So I know some shows do this but to make it more realistic they don't mention they extra money. and what about those plastic surgery shows like Dr. 90210, I mean where do those people get the money to pay for those procedures, does the show do the surgery for free as their payment for appearing on the show?
