Hi, When coding General Anesthesia, if provided by MD we would use modifier AA, if CRNA would use QZ. Would we also use QS? In my coding books, it has MAC as all service with or without medication. I think we should add it because the provider was in the room with the patient monitoring the whole time.... We have a few different opinions on this modifier.....
What is you opinion?

QS modifier represents 'Monitored anaesthesia care service'. It is just an informational modifier and should be used with primary appropriate anaesthesia modifier. In your scenario, if the provider was in the room with patient and has monitored the anaesthesia care throughout the procedure, you should use QS modifier with AA modifier.
