" the expectation would be documentation of the start and stop times or total time of the psychotherapy with an E/M service and documentation of the start and stop times or total time devoted to psychotherapy."
I am a bit confused by this. Are they saying that for 90833 you can add time spent on psychotherapy woven into E/M conversations with time spent on purely psychotherapy?
Realistically, most will do the "weaving" of psychotherapy along with medical decision making. I always put in a start and stop time (usually the first 16 min of the visit) purely to satisfy this requirement and avoid someone later on scrutinizing my notes and telling me there isn't a way to tell if I did 16 min of therapy or not. Otherwise, I'd have to put in "3:00-3:05, 3:12-3:17, 3:24-3:30" or something ridiculous like this to highlight the times I spent doing therapy. That probably wouldn't even be accurate.
