The job of the medical biller does not stop with coding and billing. Themedical biller tracks the claim until it is paid and collects the receipt(known as Remittance Advice) sent from the insurance company to the physician'soffice that verifies the transaction. The bill states the details oftransaction including what was paid, what the patient owes and how much is tobe written off, if at all. These transaction details need to be updated intothe software to balance the doctor and patient's accounts. The invoice willneed to be mailed to the patient. In case if claims are denied, you may need toinvestigate the reasons with the insurance company.
