A different physician repeats a procedure on the same day that another physician already performed, with documentation supporting the repeat. Which modifier best identifies the repeat by another physician?
Select an answer to reveal the explanation.
Short Explanation
Different physician repeats the work on the same day—modifier 77 is the name tag. Don’t borrow 76 just because it feels close.
Full Explanation
Modifier 77 identifies a repeat procedure by another physician when documentation supports that a different physician repeated the service on the same day. Distinguishing same-physician versus other-physician repeats keeps professional claims in multi-provider community groups accurate and prevents misapplication of modifier 76.
Modifier 76 for a repeat by a different physician outside the group mislabels another-physician work as same-physician repeat. Modifier 79 because every same-day repeat is unrelated surgery confuses unrelated postoperative procedures with same-day repeat reporting. Modifier 57 on the repeat procedure to show decision for surgery belongs on decision-for-surgery E/M services, not on repeat procedure lines.
Exam caveat: “another physician” means a different physician (as defined for modifier 77), not merely a different building or different nurse assisting. Operational check: identify who performed the original and who performed the repeat, append modifier 77 when another physician repeats the service the same day, document clinical necessity, and coordinate claim lines so public payers see a true other-physician repeat rather than a duplicate same-physician bill.
