@tinaesims Is the problem that your insurance won't pay, or that Mayo won't work with your insurance to handle the money. I have plan F, AARP, so Mayo sent them the bill, they sent us the check, and we paid the bill with the check. I saw no problem except that we did have to handle the check. It was OK. The mayo system is sort of creeky and rusty, but it can work. Just be sure to document everything, and keep your receipts. Put the money in your own bank account when you get it from insurance, then pay it with your own check to avoid any issues, or have the bank pay it directly. old karl
