I got a call yesterday from a collections agency (http://www.creditservicecompany.com). They are claiming I owe $18 to the hospital I stayed at in June when I injured my back. Had the right info for me (which they gave me, I didn't have to give them anything but my name), the right hospital and the right date of service. I told them I'll get back to them, and called the hospital. 3 different billing departments, and no one has any record of me owing anything. I also pulled my credit reports, which don't have anything flagged on them.

I am planning to go back to this agency and asking them for a full itemized bill in writing. Is there anything else I should be doing? I'm neurotic about my bills, so this is my first go round with this and I really don't want to end up with credit report issues, especially as we're trying to buy a house this year.
