uncovered services ordered by family doctor during annual exam

请教老猫:

We live in Georgia. Two weeks ago my wife went to have an annual physical exam in her family doctor’s office, which is a preventive service covered by our health insurance. Recently, when she received the explanation of benefits(EOB) from the insurance company, she found she is charged and asked to pay about $250 co-pay for uncovered services of some microbiology tests and urology tests ordered by the doctor without her awareness and authorization during the annual exam. She contacted the insurance company and was told she would need to discuss the issue with the doctor. But the doctor insisted that he did right job during the exam. We would like to have your opinions and advice on whether or not the doctor worked appropriately in my wife’s case. Additional information would be greatly appreciated. Thanks.
