Just received this message from my health insurance company. Does anyone know if this in effect yet? Does immigration still mandate a Thai insurance company or can we show international health insurance certificate? We live in Hua Hin and due to renew O-A October 13 - many thanks! 
It has come to our attention that there are already immigration offices in certain provinces asking for the 3,000,000 THB certificate for the renewal of your non-OA visa. In some provinces however, immigration still accepts the ‘old’ 400,000/40,000 THB certificate. We therefore kindly advise you to first check with your local immigration office which insurance certificate is needed for the renewal of your non-OA visa,
TLDR : Answer Summary
The post discusses the recent health insurance requirements for renewing a Non-OA visa in Thailand. It highlights that some immigration offices may request a health insurance certificate of 3,000,000 THB (approximately $100,000), while others might still accept the older requirement of 400,000/40,000 THB. The author seeks clarification on whether international health insurance is accepted or if a Thai insurance policy is mandatory. Comments suggest that foreign insurance may be usable with proper documentation but recommend considering Thai insurance options. Additionally, a strategy to apply for a Non-O retirement visa is mentioned, which does not have specific insurance requirements.
