Human Dental paid for a claim. According to Humana, they then later denied the validity of the claim, after almost 1 year, and then said I owe them money. They never tried to contact my Dentist who did the billing or myself. I have no record of an original attempt to collect repayment. And the billing department at the Dentist office verified they had never been contacted.This happened in September 2006. And even so, the originally billing to them was correct and, should have been paid by Humana. Now in December of 2008, Finance Systems of Green Bay, on behalf of Humana, has blemished a perfect credit record. Even after I told them this was a incorrect billing error on Humana's part. People at Humana were incompetent and now my credit report has been tarnished.
