Mary had a Brain MRI (without and with contrast) at a local hospital in Twin Falls. Since Mary had already met her annual deductible, her coinsurance amount was 20%. Her insurance paid the hospital the allowed amount of $2,370, which meant she needed to pay the coinsurance amount of $474. Had she visited Innovative Medical Imaging, she could have saved $258, since the allowed amount for the same service would have been $1,080 and therefore her coinsurance cost would have been just $216.
