Within a postoperative global period, the same surgeon performs a procedure for a problem unrelated to the original surgery. Which modifier best reports that unrelated procedure?
Select an answer to reveal the explanation.
Short Explanation
Brand-new problem, same surgeon, still inside the global clock—modifier 79 says ‘unrelated procedure.’ Don’t mix it up with the related return-to-OR modifier.
Full Explanation
Modifier 79 reports an unrelated procedure or service by the same physician during the postoperative period of another surgery. Related unplanned returns use 78; decision-for-surgery E/M uses 57; modifier 25 applies to significant separate E/M with a procedure—not to rebrand an unrelated operation.
