Charges during postoperative period

One of the physicians at the Orthopedic office I work at is taking over the post-operative care for a patient who had an ORIF of a bimalleolar fracture done by an outside physician. My physician is questioning how the visits will be billed since the patient is in the post-operative period for this surgery.
Would we bill regular E/M services supported by the notes since we are in a different practice than the physician who performed the surgery?
Any input would be greatly appreciated.
Thanks!
