Surgical Complications

“I have a patient who had a hammer toe deformity, and this required repair of the second toe. Unfortunately, the surgical site developed osteomyelitis. This complication occurred at postoperative week number four. I returned to the operating room to perform an amputation of the second toe because of osteomyelitis. I would like to hear thoughts on the appropriate modifiers. And how does the zero-day global period for the amputation play into the billing for the post operative care?”
