When a patient has insurance, they typically don’t pay all of their medical expenses. Medical billers process fees and charges covered by insurance and send invoices or insurance claim forms to insurance companies or Medicare. What separates medical billing from similar jobs in the business world, aside from their knowledge of specialized medical terminology, is that medical billing is anything but straight-forward.

Medical billing requires an understanding of insurance contracts, Medicare regulations, workman’s comp, and personal liability laws. Medical billers work alongside medical coders and transcriptionists to ensure every patient detail is correct and that treatments have been properly documented, since poorly documented treatments can result in the loss of fees.
