dentist bill went to collection in 2002. Should I pay it?

I have a $600 dollar dentist debt on my credit report. It was posted in 2002. What would you recommend I do? I had insurance at the time but its possible that they did not cover the work that was done. Since this was from 2002, should I contact the collection agency? or should I dispute it? or is it better to leave it alone since its from 2002. I appreciate your guidance in this matter

I guess it depends on your credit score now
and
if this is affecting something you wish to do

you can dispute it and hope
might do that
then
negotiate, pay and be done
ask for humble credit help
talk to both the collection agency and the original creditor

if you have new good credit this should not hurt your score much even if they do redate it
but i would make sure they at least did not re date the account
