There is a debate going on between coders here. What modifiers can you use with an asa code? Can you use sugery modifers such as 80, 78, and 53?? For instance there were 2 anesthesiologists working on a pt at the same time and a coder wants to code 00542 AA/80. Can she do that? I wouldn't think so because they are not acting as surgeons. What do I do for this chart!!
