Thank you so much for your answer! The patients do have a diagnosed mental health condition, and are assessed by a psychologist to determine if they have decision making capacity by evaluating them for the ability to evidence a choice, ability to understand relevant information, ability to appreciate the situation and consequences, and ability to manipulate information rationally. Basically, do they have the ability to make their own medical decisions. The psychologists meet the documentation requirements for a 90791, and also usually perform one or more of the screenings I mentioned previously. I did look at the 99483 code, but did not think psychologists could use that code as it includes medication reconciliation, which does not fall under their purview. The 90791 on the other hand does not seem like the best choice, as the process can occasionally last longer than the proscribed max of 90 minutes for that code, and the clinicians want to be (and of course should be) compensated for their time.
