WHat does closed/current and paid,closed/collection mean?

They seem a bit ambiguous.

I have a collection on my account from a hospital bill that said paid,closed/collection account. The dates it was opened 1/2006 and last reported 1/2007 do not coincide with ANY visits to the hospital (I was in car wreck 2/2005). Does the paid/closed/current aspect warrant a dispute to have it removed? Its in the negative section obviously.

I have a paid/closed/current, was past due 60 days on my report...what's the difference?

I have a closed/current mcydsnb account from 2000-2001. It was last reported 12/2007. I"m not sure what this means either?????

My last ambigous example is Open/Current for a card that was closed 4/2006 .???

THANKS!
