French living in the US here(California). I had to go to the general practitioner and I still don't understand how they can come up with prices as high as $400 when it cost me 22 euros back home for the exact same service.

Also my insurance company in France would rather pay for my flight ticket to go back home instead of going to the hospital in the US.

I've been in the US for almost 2 years now and it still puzzle me that I had to pay for STD test(!) and I still don't understand the US healthcare system.
