Hi dismama, I tried to click on the thanks button at the bottom of your post but it said I do not have permission to access this page, so I will thank you right here. I was going through my file cabinet (which needs to be reorganized badly)and found the What You Need to Know handbook for SSI, and came across the reviews section. You were right dismama, I read that it said about 3 or 6 years. I never heard the term diary date, thats informative as well. I know my mind will rest at ease when I can get insurance to buy my meds with. I need documents from the doctor too so I have it handy at my first review. Dismama and youtoo1955, you have both been a great help to me.
