Question: An MD consults on a patient in the hospital early in the week and indicates the plan is for the patient to have surgery later in the week with a partner. The NP for the same group rounds on the patient for the rest of the days prior to surgery checking neuro status, etc.. For which visit do I use the 57 modifier? If I use it the day the decision for surgery was made, the rounding visits become unbillable(global), correct? Any input appreciated.
