What Is Modifier 78?
Modifier 78 is appended to a procedure code to indicate an unplanned return to the operating or procedure room by the same physician for a related procedure during the global postoperative period of the original surgery.
- When complications require a return to the OR or procedure suite during the global period, document the relation to the original surgery clearly and use Modifier 78.
- Use Modifier 79 only when the return is for an unrelated condition.
Modifier 78
Also known as: Unplanned Return to OR Modifier; Related Procedure Modifier
Modifier 78 is appended to a procedure code to indicate an unplanned return to the operating or procedure room by the same physician for a related procedure during the global postoperative period of the original surgery.
Definition
Per AMA CPT, Modifier 78 covers a related, unplanned, return-to-OR procedure during the global period — typically to address a complication of the original surgery. Payment is reduced (typically to the intra-operative portion of the procedure's fee, around 70-80% of allowed). The new procedure does not start a new global period, so subsequent post-op care still falls under the original procedure's global period. Modifier 78 differs from Modifier 79 (unrelated procedure) and Modifier 58 (planned/staged procedure).
Example
A patient develops postoperative bleeding 5 days after an abdominal surgery and is returned to the OR for hemorrhage control. The hemorrhage-control procedure is related to the original surgery and unplanned — append Modifier 78. Modifier 79 would be wrong because the return is related; Modifier 58 would be wrong because it was unplanned.
Common Misconceptions
Modifier 78 reduces payment to the intra-operative portion only — pre- and post-operative work is bundled. The original procedure's global period continues; do not reset the global clock with the related return.
Practical Application
When complications require a return to the OR or procedure suite during the global period, document the relation to the original surgery clearly and use Modifier 78. Use Modifier 79 only when the return is for an unrelated condition.
