Medical Insurance Coding & Billing Specialists work in the hospitals, doctors' and insurance companies' offices. They analyze patient records to determine legitimacy of admission, treatment and length of stay in the health-care facility, and verify that the patient's costs are covered by either a government agency or a medical insurance company.

Medical Insurance Billing Specialists create fee schedules for patients who cannot afford to pay the bill right away and keep track of those schedules until the amount due is paid.
