Was this bill forgotten by a medical provider, and do notices need to be sent before collections?
check the DATE OF SERVICE on all your invoices carefully.  It's possible you actually DID pay already. Sometimes when a medical provider gets "mostly" paid by a third party insurer, they just drop the (small) remainder, as it's more cost than it's worth if it is a trivial amount.  Alternatively, they wait until you show up for another office visit, and "ding" you then!
