Do I need health insurance to re-enter Thailand with a non-O-A retirement extension?

Now that we sussed out what visa/extension you're on (and what one you're not on :O)

You would ONLY need the 100K USD covid policy and the other entry requirements to get back in.

AND

as long as you bought a re-entry permit before you left (and your covid insurance was good for a year) you'd get stamped in until your current extension expires (March next year) when you came back. :)

First off how did you get a year long O-A visa extension without showing proof of the 40K/400K mandatory insurance policy from a thai carrier?

If you are concerned about getting yearly insurance and you are starting over then you should be aware that there is a pathway back to Thailand by getting a non-O visa that doesn’t require yearly insurance. You still need the Covid insurance to enter.

I debated allowing this post to appear tonight as its 11:00pm here in Thailand.

But to start...

What does your OA extension of stay show as your OA insurance expiration date?

You have to have OA compliant health insurance to initially obtain the OA visa in your home country...then to extend it in Thailand requires the 400,,000 inpatient/outpatient health insurance from an approved Thai insurer.

To cut to the quick...the least extensive way to meet the health insurance is to buy the LMG OA policy.... Issue ages thru age 74.

To leave and reenter Thailand will require the US $100,000 COVID health insurance for the time you will be stamped into Thailand on arrival.

The rates for the COVID ONLY policy may be higher than that of a new OA compliant health policy

If you are from a hi covid risk country such as UK US Poland etc

With your age known and what your passport nation ...is how I can better advise you.

As it may be best to buy a new one year OA compliant policy which has both insurance needs covered.

You asked do you need health insurance to return...

YES...OA COMPLIANT. as you are on an OA based extension of stay.

And will also need have the insurance include cover for COVID $100,000 in medical expenses.
