Has anyone done this?

Was chatting with a coworker about the struggles im dealing with daily associated with my HH. He casually said, "why don't you just tell them you need surgery?" I have a barium swallow on the 11th, is it realistic to go in and explain the way this has affected me and ask for a surgery? Is this something insurance would approve if the doctors agreed? Any advice would be appreciated as I have been struggling for years
