ANY help would be greatly appreciated. My surgeon harvests veins for the cardiothoracic surgeon to perform the coronary bypasses. He does not dictate this and we only charge for assisting the cardiothoracic surgeon by appending modifier 80. My surgeon wants to know the codes for this and if he should dictate and how PA's and Tech's charges are billed. From what I can gather the rule is if a surgeon performs the graft procurement we add a modifier 80 to the 33510-33516 codes...does anyone know if the procurement needs a separate dictation and how is it billed for a PA (AS?) or hospital Tech? Again, greatly appreciated!
