Can I use Medicare and supplemental insurance for a retirement visa in Thailand, and can I self-insure?

True medicare will not cover you outside the usa at all and is not recognised in thailand

Also be aware that Medicare will not cover you in Thailand. Like someone else said maybe a Medicare Advantage Plan might offer some coverage.

No insurance needed for a non-O retirement visa, but to answer your question, no, Medicare cannot be used to satisfy the insurance requirement for a non-OA retirement visa. There are only specific health providers the government requires you to have in order to satisfy the requirement. As for self insuring, just weigh the benefit of paying a small amount for outpatient services as you need them vs a large health insurance premium that might save you financially if you are ever in a catastrophic accident or have a stroke leaving you in the hospital for months. Up to you.

No

Get the non O so no insurance required. You can get travel insurance up to a year. That gives you plenty time to get here and figure out what you want to do about long term insurance.

You don’t need insurance for a non-o retirement visa, however it is prudent to have when you are here, or have $0 in the bank ringfenced for a medical emergency

Don't know what your supplement plan is . Medicare Plan C is a private company of your choice. Some plan C cover limited care for tourists in other countries.

I agree with Brandon above, no insurance needed..

The non-O visa, which most people use for retirement, does not require any insurance.

It's only the non-OA that requires medical insurance, and you would not be able to use your own insurance.
