Medical billing is a huge undertaking for most medical practices. It requires an incredible amount of data entry, follow up, and paperwork in order to get the right pre-certifications, prior authorizations, and insurance verifications that you need. Some medical practices think that this is just part of the business of running a medical practice. While it's true that this sort of insurance paperwork is a necessity, it doesn't necessarily have to be done in your office. In fact, doing it yourself could be negatively impacting your practice.
