The patient fell in Nov. 2010, he had an ORIF for a fractured hip. He fell again during the post op period, December 2010 with a diagnosis of periprosthetic hip fracture. He the had an ORIF with left hip hemiarthroplasty revision.

Should I use 78 modifier for unplanned return to OR by the same physician for related procedure during the post op period, or 79 modifier unrelated procedure by the same physician during the post op period, or is there a modifier more accurate?

I am not sure which modifier to use, it was the same area but a second fall.

Thanks for any help.
