Do the Health Insurance Dates Need to Align with O-A Visa Extension Dates?

This question is in regards to the new health insurance requirements for extension of stay of type O-A visa. Do the dates on the new health insurance requirements have to align with the exact dates of your type O-A visa extension of stay? I have a group policy from Pacific Cross through the expat group in Pattaya that I think meets the Thai immigration requirements (out patient and in patient coverage). However, my annual policy coverage is May 2020- May 2021 and I will apply for another extension of stay in about 3 months. I have been on the Thai immigration site looking for this requirement but have not found it. Can you please provide the link as to what the exact health insurance requirements are for type O-A visa extension of stay.
