Wiki Pf arthroplasty to tka

[cpccpma]

Good morning! I would like some input on the above procedure-I'm leaning towards 27487-52. The doc also performed patellar autologous bone grafting-the code he selected is 27416 however what is throwing me is he states "I felt we did have the opportunity, given her young age, to use her cancellous autologous bone from our bone cuts to try and bone graft her patella to restore bone stock, if for no other reason to protect her extensor mechanism and hopefully allow for future or down-the-line patellar resurfacing as needed" so I do not feel this is separately billable. Thoughts?

Thank you! Michelle B

27416 is not supported

27416 is when the doc takes a dowel of bone from a non-weight bearing area of the femur and places it into the condyle of the distal femur that needs support since it is within the weight-bearing part of the knee.

The doc took the bone from making the cuts for the TKA to use in the patella. Allograft, if needed, is already built into the revision code.
