I need to see more info on the routing slip. Outstanding insurance over 30 days from the original date of service is important. For example pt had a build /crown and expected insurance is $800. The claim is outstanding 3 months. They are back for a cleaning and more fillings. Current Route slip would show they have $800 balance and $800 out to insurance and may have ins available of $700/$1500 so staff is allowing them to continue to get treatment when ins may never pay for work already completed or future work.
