I was taught to address the reason you are there (acute skilled needs) and not get into chronic problems. If they are diabetic, note that they are "independent with diabetes management" if appropriate. If more than one MD involved in case, note who manages PT/INR for example, on a postop patient. If patient is attending outpatient PT, I note it. I was also taught that a diagnosis must cover all meds. For example, Lexapro is listed, so must a diagnosis for depression. Hope this helps!
