Review patient records and assign procedure codes and diagnosis codes. These codes have to be accurate because they are used in the patients’ insurance claims. Use special billing software to submit insurance claims to insurers. Be responsible for keeping up-to-date with insurance procedures, to insure that claims are submitted correctly. Interact with patients directly to get their insurance information. You might need to talk with patients about the charges, explain what the billing means, and help patients understand what their benefits cover. Contact insurance companies directly so that you can follow up on claims that are still waiting to be paid. Review payment and receivables records to make sure that your employer is receiving accurate and timely payments for the services it provides.
