A patient with a carotid body tumor and inflammation around the carotid body has had an ultrasound and MRI with imaging that indicates a larger amount of inflammation than normal in this area. His surgeon elects to undergo laparoscopy of this area to obtain more information before scheduling surgery to remove the tumor, to better prepare for whether the carotid artery will have to be excised as well. The patient is scheduled for surgical laparoscopy to explore the carotid body. What is the correct CPT code for this procedure?
