I honestly, don't know? Summary sheets, of appointments only became available, last year, in my doctor's office. I'd been under treatment/ care of my PDoc, since 2009. Perhaps, for billing, within the first several months. Before treatment, the nurse/secretary mentioned the break down of how the appointments would go. The initial 45minute consultation, followed by a couple more 15minute appointments. I want to say I started in early January, after a three month wait, by April I was prescribed an AD. Perhaps, that's when the billing code/diagnosis was added? Last year, I realized what I have, for a label. Knew I was being treated for anxiety and some depression.
