that doesn't look like it, it is the codes that tell the claimant how they were approved for ssdi, i dont think there is a low med or high.
blindness would be a line item ,. paralysis would be another line item code
than there are codes if you were approved because of a bunch of factors, say lots of back problems and working in a heavy lifting industry for over 20 years, no college education, age 55 or over.
