That's weird you didn't get a letter. I had my review last spring. I had to fill out a form and so did my therapist. A few weeks later I got a letter saying I was still eligible. I don't remember if it said anything else (hopefully I will find it if it did) but I do remember a letter for sure (I was so sick that little was registering. It was pretty easy to be sure I was going to be re-approved).
