If a physician orders a test for example a carotid artery ultrasound how can a consumer find out the best cost they will be charged? Hospitals charge more than outpatient Independent Diagnostic Testing Facilities (IDTFs) or if the doctor can provide this service in their office. Efficiency of care costs for the consumers who have large deductibles or co-pays should be informed on how to shop around. If the charges at the hospital are $900 and the IDTF or the physician can provide this service in their office charges $234, there is a big difference to the consumer. Will physicians be tracked on the the efficiency of care costs? A physician should understand the cost of a test and should have available recommendations for their patients.
