So I have a procedure where the doc did a posterior interbody fusion of L4-5 and L5-S1. But later after he documents laminectomy and discectomy with this, he documents placement of pedicle screws bilaterally at L4, L5, and S1, then he does a rod placement, and documents sponylolisthesis reduction. He wants to get botht the 22630, and the 22612. I don't know enough to know if you can code these in same op session, or if this is even appropriate. It would seem to me that you can only code one technique or the other, which in this case would be the 22630, but I don't know for sure at all. Please help again! thanks again!!
