As a remote medical biller, your responsibilities are you review the treatment record of a patient and submit the appropriate information and paperwork to a healthcare insurance provider or federal medical program, such as Medicaid or Medicare, for reimbursement. You also review any pre-authorization paperwork and eligibility concerns for the provider. Nearly all medical facilities, from small outpatient clinics to large hospitals and medical centers, rely on the services of medical billers, but now that medical files and patient histories are digital, most of these positions are work from home positions.
