I was approved at age 52 and went through the short CDR's at ages 55 and 58. I was due for another one when I turned 61 last year and but still haven't received anything. I figure they're tied up with new applications and can't get to me yet. When I'm regular SS retirement age, I guess they'll stop coming after me. Until then, I keep all my records updated--MD receipts, calendar showing all appointments and lab tests, trips to hospital, etc. I also have rough draft letters for the two pertinent doctors with "suggestions" on salient points they should address--not simply, this patient is disabled. It ain't over 'til it's over!
