CCI Says 27446 With 27438 Is OK

Question: I have a physician who is doing a medial unicompartmental replacement and a patella resurfacing. Should I code this with 27446 and 27438-59?

Answer: You should be able to report 27446 (Arthroplasty, knee, condyle and plateau; medial OR lateral compartment) and 27438 (Arthroplasty, patella; with prosthesis) together. CCI edits do not bundle 27446 and 27438, so you do not need to append 59 (Distinct procedural service) for separate payment.
