I rec'd a dispatch from a collection agency concerning a bill from a laboratory biopsy made oct 2002?
That's a sentence next to a question mark at the completion of it, not a question.
This is a medical test.
Try contacting your doctor from that time to see if the bill was ever compensated.
It could be a mistake or an insurance mix-up
Don't pay anything unless you're sure its a legitimate charge.
Answers: Yeah, and? If you had the procedure, you owe the money. Bottom line: payment up. (Five and a half years after the fact is too long to research it - that ship sail five years ago.)
