Health insurers limit advanced scans
AP/Yahoo News, March 24, 2008
Insurance companies are looking closely at advanced medical scans like CT scans due to spiraling costs and safety concerns. Health insurers are requiring more pre-authorizations before patients can receive these types of scans, and setting restrictions such as mandating that the imaging equipment and medical staff operating it be credentialed in advance. Some doctors also agree that emerging evidence shoes that the scans are being over-prescribed.
