Both the physician’s coder and the ASC’s coder should report the appropriate control-of-bleeding code appended with modifier 78 (Unplanned return to the operating /procedure room by the same physician …) because the procedure occurred within the ASC’s “same-day” global period.

Red flag: For postoperative operations beyond day 1, realize who you code for makes a difference in your modifier coding. The ASC coder should follow the “same-day” global rule, but the physician’s coder should follow standard global period rules from the fee schedule, says Annette Grady, COSC, CPC-H, CPC-P, CCS-P, PCS, FCS, senior orthopedic coder and compliance auditor for The Coding Network.

Example: Suppose in the above example the physician returned the patient to the ASC the day after the initial...
