Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 27446 covers

An orthopedic surgeon uses this code for a knee arthroplasty confined to one femorotibial compartment: medial or lateral. A typical case is replacement of the damaged surfaces in one compartment for isolated disease, rather than replacement of the entire knee. The operative report should identify the compartment treated and describe the prosthetic reconstruction. This code is used for partial knee replacement, not a revision merely because the CMS short descriptor uses broad revision wording.

Choose the code by the extent of the arthroplasty documented, not by disease severity or the number of implant pieces. Distinguish a one-compartment procedure from arthroplasty involving both compartments or total knee replacement. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. For bilateral procedures reported with modifier 50, CMS pays at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
