Hi, I apologize if my comment is not relevant to the conversation, but this specific comment seems very useful to my personal situation and I desperately need some further insight on the matter. I am an US expat living in a country with free universal healthcare. It is also affected by a war that started a year ago. I could not leave then because I had a life threatening health emergency and had to spend 2 month in a hospital. Luckily, it was finally resolved, but i need to stay on heavy meds to remain in remission. And they just discovered that I have a tumor in my kidney that requires major surgery. To have surgery here is almost certain death from complications/infections/neglect (i've seen it happen) So I have to go back to US. My plan is to move back, buy a "cadillac" health plan on ACA market place. I understand that one can enroll after enrollment period if moving from overseas. Then try to get a treatment. What is the best approach to get the treatment as fast as possible? Is concierge thing only way to go? I checked major cancer centers in an area where I plan to settle, they are all accepting new patients. Does it mean I can go directly to them and expect them to treat me right away? Most important question. What if I denied insurance or it is delayed and I end up uninsured? Is there a way to get a treatment first and pay later/negotiate price, payment plan, etc Any advice is appreciated Thank you
