According to American Academy of Orthopaedic Surgeons (AAOS), normally, this scenerios should be coded with CPT code 27487. The revision code includes the removal of the old prosthesis. However, depending upon documentation and the situation, this could also be coded 27447 and 27488 -51.

Note: This is not a revision of a total knee replacement. Except for removal of a partial tibial tray and femoral metal runner, the procedure is the same work as a primary total knee.
