Do we need to extend our health insurance coverage for the LTR WP visa if it expires before we receive our visa?

LTR WP visa - health insurance: we applied one week after annual insurance renewal and it has now been about five weeks, so in two weeks we will have only 10 months remaining on our insurance. If we don't get the visa within two weeks, will we somehow need to extend our insurance coverage to hit 10 months again? This would be difficult as it's international insurance with annual premium. We were planning to do the e-visa through our embassy (Manila), but if they are slow perhaps doing it in Thailand would be better? Any comments from LTR holders with insurance (not money in bank) would be helpful. I have found BOI responsiveness not as good as advertised here.
