Any visit provided during a hospitalization with a surgery (except critical care and emergency room visits) by the physician who performed the surgery would not be separately billable, as they would be considered part of the global care (including post-op) of the patient. Other providers involved can bill for appropriate visits.
When a critical care visit is unrelated to the procedure with a global surgical period, critical care visits may be paid separately in addition to the surgical procedure. When critical care is unrelated to the surgical procedure, append the modifier -FT (unrelated E/M visit during a postoperative period, or on the same day as a procedure or another E/M visit) to the critical care service. For more information, see our article on critical care services.
However, after the hospitalization, if the patient sees the same physician outside the hospital and during the global period, modifier 24 rules would apply to any potentially separately billable visits.
