I began receiving SSDI in February of 2013 with an onset date of May 2011. I was 54 years old and will be 59 in March of 2016. What role does age play in the frequency of a CDR? At this point I have not received a CDR. In addition is the CDR initially done on the short or long form and am I required to send medical files from provider once a CDR date is requested?

Thanks for the help.
