Used in 2011 for supplies. on 11/12/12 I rcvd a bill for $700. The mgr did not file ins, but continued to send supplies the entire year. They billed 2011 ins, even tho 2012 ins was provided. Said I was resp. Claimed they were out of network, when in reality, they just did not file the PA (prior autho) 1/1/12. Mgr told me my doc should have done PA. Called my doc, said NO prov would have to do PA. Called mgr again, would not return call. Called billing, billing said call mgr. Left VM for Mgr. Called billing who said mgr was at fault. on 11/27/12 billing said "she'd take care of it." 2/9/13 rcvd bill for $507.78. 4/1/13 billing said mgr did not provide something, they would resubmit to my ins. Billing said they would adjust copay off. 4/12/13 rcvd stmnt showing charge in 2012 paid by ins and co-pay for uncvd chrgs was $435.00. Pd monthly. By 6/3/13 called, verified last pymt of $64.10. 9/4/13 rcvd bill for another $7.98, that they won't write off.
