HELP!! Is this enough for Complex repair 13120 or do need to ask for an addendum?

The left knee was then opened with #10 blade. A Subvastus approach performed. There was extensive adhesions and scar tissue within the medial and lateral gutters and the suprapatellar pouch. We excised this with cautery. Once we did this we had improved flexion to 115 degrees. We then cleaned out around the PCL and improved flexion to 125 degrees. I then assessed extension, which was full. I released the tourniquet, got good hemostasis and injected the local cocktail around the knee. I then wash with pulsatile lavage containing Rifampin. A Hemovac drain was placed. The wound was then closed with #2 Quill, 2-0 Vicryl and staples.
