I have 6 physicians in my office. One of the Dr's specializes in surgical oncology. He saw a pt in the office and the patient had a hernia. He does not do hernia surgery and asked another Dr that was also in the office that day to see this patient for the hernia. How do I bill for the second Dr's consultation? Is there a modifier that I should use since I will now have 2 charges- one for each of the Dr's on the same day for the same group.
