i've heard/read that you can sometimes deal directly with imaging centers and pay much less out of pocket for these scans. In many cases, a collective of physicians actually own the equipment and are perhaps guided by the Hippocratic oath to provide the service at a much lower price. I realize this sounds naive but I played soccer with a physician/owner that confirmed this after one of our teammates needed a scan.I'm not sure that this fits in this discussion, but I had had to go the ER for chest pain, turned out to be benign. However on the CT scan, the Radiologist made note of a 5 MM nodule on my lower lung. The ER NP. recommended a follow up scan, and my primary Dr. agreed and ordered the test. Well, in steps BCBS of Michigan, and denied prior authorization, because the body part had been scanned within their 6 month window. My Dr. appealed the claim, but it was still denied. So I will wait my 6 months, and ask my Dr. for a followup CT. She wanted the CT, because original one only showed the lower lung and not the entire lung.
