This works because moving counts as a significant life event and something like moving (say to a friends house or parents for work related things and a couple extra things like a bank statement) are generally enough. Take it one step further and update your license and it’ll be even harder to call BS and deny your coverage.
Wait a little bit and move back to the house you probably never left in the first place. Hope this helps someone get insurance if they fell through the American cracks of employer based health insurance
