We are a practice of 5 general surgeons. In rare instances we will round for another surgical physician (only 1 doctor in his practice) on HIS patients when the need arises and he cannot be there. I would think we would not charge a consult code but a subsequent day E/M since we are rounding out of courtesy and not taking care of his patient. Is there also some type of modifier to use in this case to differenciate that this is not our patient? Thanks for any input.
