I would suggest to call the radiology office and find out what the charge is and if they offer a prompt pay discount or payment plan options. I work in medical billing and while small independent offices have room to negotiate fees with patients, larger facilities do not. (until after it is on a payment plan or goes to collections.) However they should allow you to make a partial payment and set up a payment plan for the rest. Usually the charge is around $800 but varies from place to place.
