The trump administration did an executive order that forces hospitals to list all their prices. Imo easily his best move. Now, the current implementation does not work for a myriad of reasons that are mostly "hospitals have good lawyers and don't want to reveal prices" but the law can be fixed. A working implementation would make price shopping easy as someone would build a centralized site and you could have your health care provider put in the treatment needed along with your location and distance willing to travel.
