Has anyone figured out a smarter way to handle billing in a busy urgent care clinic?

Working in a high-volume clinic helped me to understand that small billing mistakes accumulate so quickly. We experimented with various workflows and as we proceeded with it, an urgent care billing company allowed us to identify where the claims were stalling. The actual solution was to monitor the reasons of denial on a weekly basis rather than monthly. Wondering how other people in this group are able to maintain their billing system without overloading front desk personnel.
