    What code do you recommend?

    Patient had a prior unicompartmental knee arthroplasty.

    Is now going to a Total knee arthroplasty.

    Is that considered a revision ? 27487?

    I am thinking yes, but would like confirmation.

    This is a very interesting situation and would be interested in others' opinions as well. I do not think that I would use 27487 because that is for revision of a total, which is not the case here. I would be more inclined to use 27447, possibly with a 22 modifier for removal of the unicompartmental hardware.
