Do I Have To Repay My Auto Insurer If They Pay My Medical Bills?

Do I have to repay my automobile insurance company if they pay my medical bills from my medical payments coverage and I recover a settlement from the at-fault driver? 

Probably.  Most automobile insurance policies that have medical payments coverage require that you re-pay them if you make a recovery from the at-fault driver.  Under certain circumstances you can force the company to reduce the amount of the re-payment.  Your lawyer can help you with this issue.
