Medical tourism, from the States to elsewhere, has been a "thing" for some time, maybe a decade(?). I'm sure it's been done individually by out of the box thinkers well before that.

It's great that businesses like in the article are making this a bit more accessible and known, it will put some cost pressure on Stateside providers. Also help people save some money by going outside the States, or even get care that just would not happen otherwise.
