I don't understand what you are trying to filter out here. /^5,/d
will remove all lines that start with "5,". I don't understand how
that is useful here.

Here, you need to set IFS. Also, in the first line of diffsum,
INSERTED gets the text string "INSERTED" rather than an integer
value. Try:
sed -n '2,$p' diffsum | (IFS=','; while read INSERTED DELETED MODIFIED
FILENAME; do if test $INSERTED -gt 0; then echo $FILENAME;fi;done )

I like that. Your invocation of sed is cleaner than mine...
Even better would be:
for line in $(sed 1d diffsum); do...
In this last one, your problem is a simple typo. replace
"insert" with "$insert"
Thanks for the help.
