Wiki help with knee revision

[tmgexp1@yahoo.com]

Can somebody please clarify this for me? I thought that any time somthing is done to a joint that has already been replaced once, you would use a revision code. However, if a total knee is infected, doc removes the prosthesis, implants the spacer and then weeks later puts in a new knee, is that a revision code or should I be using 27447-58, 22? I have read articles that say do it one way and then I find an article saying the complete opposite. Does anyone know the most up-to date, current guidelines for this? I would appreciate any help.

In this case I would say code the removal of the replacement and if the dictation on the surgery for the removal states that the doc is going to put in a new prosthesis, and its within the 90 day global period, you would code the revision with a 58. However, if its after the 90 just code the revision with a right or left modifier. 22 doesn't make sense when the code describes a revision
