A medical administrative assistant performs numerous clerical and administrative duties for a specific doctor, clinical unit, laboratory, or department. The range of your responsibilities in this career depends on the type of office in which you work, but typically you answer the phone, schedule appointments, check in patients at the front desk, have them fill out any necessary paperwork for their patient records, and deal with billing, insurance claims, and accounting tasks. You also make sure that the office is kept clean and handle inventory stocking.
