Regarding foreigners who are currently living in Thailand and have a Non-Immigrant Visa (O-A), an insurance certificate is strictly required to be presented to Immigration when re-entering. They can apply for an insurance certificate with the listed companies who participate in this scheme, as follows: https://longstay.tgia.org/…/companies_contact…
Those who have a Non-Immigrant Visa (O-X) are requested to contact authorized insurance companies directly to apply for a Thai health insurance policy. Any inquiries on completing the insurance application can be addressed at each insurance company.
