Simultaneous Bilateral TKA with two surgeons

One surgeon performed the right TKA and the other performed the left. Does each surgeon bill their side with no modifier other than RT or LT? Do they bill 27447-50,62?


  • Each surgeon would bill 27447 with the 62 modifier and RT or LT based on which provider worked on which side. If they both worked on both knees than each surgeon could bill with the 50 modifier along with the 62 modifier. Be prepared to send both op notes. I've yet to have one where an insurance processed before asking for the documentation.
