Is health insurance required when renewing a Non-O retirement visa in Thailand?

There are two types of health insurance needed for Thailand: for entry and for extension of stay (only a Non-OA for the latter). All non-Thais must have $50k USD coverage for the period of time they get for their initial permission of stay. So enter on a visa-exempt entry get 30 day permission to stay, need 30 day insurance coverage. Enter on tourist visa get 60 day permission to stay need 60 day insurance. Enter on 90 day Non-O, need 90 day insurance coverage. Enter on Non-OA get 1 year need 1 year insurance. Enter on re-entry permit of Non-O visa get stamped in for time until extension expires. Despite this rule there have been some reports that only 30 days insurance is needed for entry or to get a Thailand Pass.

Then when you extend a Non-O you don't need insurance, when you extend a Non-OA you do. The coverage is for 400k baht inpatient and 40k outpatient. This is scheduled to increase to 3 million baht coverage by October 2022.

Thanks! I am due to extend mine in June and have been trying to work out if I need insurance to do this

I am going to uk for a month before then, so I would need covid insurance up to the renewal date?

Only issue is temporarily leaving and returning where you’d presently need covid insurance for the remaining length of your O visa!

There is no insurance requirement for an extension of a Non O. If you entered with a Non OA then there is.

You don't need insurance for an extension of a non -0
