What documentation do you use to code anesthesia cases? The docs I work for give me the Anesthesia Summary and it will have a diagnosis which doesn't always match the OP note. Also they may give me an ASA code of a 3 or 4 with no supporting diagnosis. I work in a hospital so I have access to OP notes and medical records can I use this to support the level even though the anesthesiologist did not provide the information? I'm trying to be as thorough as possible without crossing any lines and I am still very new to anesthesia coding so any advice is greatly appreciated.
