Medical billing is the preparation of invoices for procedures rendered, which are then given to patients and insurance companies. Medical billers act as the financial waypoint between patients, providers, and payers. Without billers, healthcare providers could not be reimbursed for the procedures they perform (medicalbillingandcoding.org).
