our surgeon performed shoulder arthroplasty and postoperatively, during transfer off the bed, a shift was appreciated. Postoperative x-ray did show that the humeral hardware was protruding through the lateral cortex. Decision was made to revise the humeral component and that happened the same day, within few hrs from the original sx. I coded 23472 for initial sx and 23473 with 78 mdf for revision of humeral component only. Not sure if this is correct. Any help is greatly appreciated. Thank you
