I am now coding for a Plastic Surgeon that has joined our surgical group and need some assistance in coding a breast reconstruction.

The doctor performed 2 reconstructions so far - both were Immediate reconstruction following mastectomy with tissue expander, placement of Alloderm and one was Intermediate closure, the other was complex closure and done bilaterally. How would I code this? I have 19357 for the procedure I believe, but would I also code the Alloderm placement and the closure separately?

I've tried this question on other forums, but have gotten no response. Any guidance would be great!
