Insertion of patellar component following TKA
A patient with a previous left total knee arthroplasty (TKA), without initial replacement of the patella, presents for resurfacing/replacement of the patellar component and replacement of the original tibial polyethylene liner. The extremity was exposed using the prior knee incision. Sharp dissection was carried down to the fascia followed by a medial arthrotomy. The polyethylene liner was then removed. The patella was everted and prepared using an oscillating saw. The trial liner was placed achieving full extension and flexion with excellent stability with a centrally tracking patella. All trial components were removed and the final polyethylene liner component was inserted into the tibia. The final new patellar component was cemented into place. What is the correct CPT code(s) for a revision of a total knee arthroplasty when the original tibial liner is replaced and patellar component is inserted for the first time? ...

Article Overview
This article explains a specific total knee arthroplasty revision scenario involving resurfacing or replacement of the patellar component along with replacement of the tibial polyethylene liner. It is relevant for orthopedics coders, surgeons, and reimbursement staff who need to understand which CPT code applies when the patella is being addressed for the first time in the setting of a prior knee replacement. The discussion centers on procedure classification and coding selection for this type of revision case.
Why This Topic Matters
Accurate reporting of revision knee arthroplasty services depends on correctly matching the operative scenario to the appropriate CPT category. This matters for compliant claims processing, consistent code selection, and avoiding miscoding when multiple components of a prior knee replacement are revised.
