<prompt> Human: Hi PF,My father is a US citizen but lives and works in a country with national healthcare. He had a heart attack a few days ago while visiting in the US California - ambulance ride, stent insertion, and several days of observation later he is looking at a 100k bill. I called the hospitals financial services and they said they can give a 50 discount with no insurance, but even then thats still a significant amount to pay. We are looking into how much the national insurance can cover for overseas emergencies probably not too much as US health costs are ridiculous, and the hospital mentioned some other financial assistance available pending submission of previous tax returns.Is there anything else we can look into? Medi-cal? Other programs? Thanks for any help.  <response>: This is complicated enough that you should look into hiring a Patient Advocate, especially one with international experience.
