What is Modifier 78?
Modifier 78 is used when the same physician must return a patient to the operating room during the postoperative period to perform a related procedure because of complications or other unforeseen circumstances following the original surgery.
Unlike Modifier 58, reporting Modifier 78 does not start a new global surgical period. The original global period continues.
When to Use
The patient returns to the operating room unexpectedly.
A complication develops after surgery.
The procedure is related to the original surgery.
The same physician performs the return procedure.
Documentation Requirements
Document the original procedure.
Explain the complication requiring the return to surgery.
Support medical necessity.
Include a complete operative report.
Document that the patient returned to the operating room.
Examples
Example 1
A patient develops postoperative bleeding after abdominal surgery and is taken back to the operating room for hemorrhage control. Modifier 78 is appropriate.
Example 2
A patient experiences wound dehiscence following surgery and requires an unplanned return to the operating room for wound closure.
Billing Tips
