SSDI CDR question
 

I have looked high and low and cannot find a list of codes for the SSA CDR= Scanline 2 –
Field 1 – Medical Diary Reason/Type

Does anyone have this list? Mine has a number (3) and I've read where it's typically a 3, 5 or 7, depending on how frequently they send out the CDRs....but my friend's has a letter (N)

Anyone know what the N means? I know my 3 means I'm sent a CDR every 3 years-ish.

Thanks!
