I must be very lucky with not having to pay for bone scans, MRIs and CT scans. They are all covered by Medicare.
My oncologist purposely sent me to radiology rooms which bulk bill MRIs. I was a bit reluctant to go to this practice at first because it was their mammographer who had burst one of my implants. But, seeing that it had been eight years since that happened and it was a different test, I went there to have my MRI.
