I know several people are saying the money must be transferred from overseas to fund the 800K but that was not my experience. I never had to show anyone anything and it most definitely was not transferred from outside of Thailand.
I’m not saying to do this because everyone’s situation is different but that’s what happened with me.
Depends on where you are going. In Pattaya Bangkok Hospital is a direct billing FMP provider.
I haven’t done it yet but was told by those who have once you have signed up through the international insurance section when you get seen for a service connected condition you just sign your name and go on your way.
Also, as stated already if you get a Non O visa no insurance is required.
