if anyone can help on this one, I have an issue, a failed ankle arthroplasty was done, with removal of the hardware and an anti biotic spacer implanted, six weeks later, the spacer was removed and a revision was done, my thoughts are the first surgery should be just 27704 for removal of the implant, the second would be 27703 and another 27704 for removal of the spacer and the revision. Any thoughts?
