Our doctors see patients for an office visit and bill V76.51 when they are going to have a screening colonoscopy. They are coming into the office because it is time for their colonoscopy. They do not have any symptoms but the doctor does go over their history and everything else. We bill the office with V76.51. We usually do get paid from the insurance company but one insurance company refuses to pay us. They are saying we are billing with the wrong CPT code. Does any else bill like this or are you billing differently?
