That's the most obvious pick - US medical industry is so famed for being obnoxiously expansive that even their own movies makes fun of it.

Just from the top of my head I remember two scenes from two different movies - the one from Hangover II where Phil gets shot and gets treatment in Bangkok hospital ("10 dollars - how is this even possibile") and from some other comedy where one of main villans, literal rocket scientist, complains that he had no other choice because he have four children with braces and how he could possibly afford that.
