Health-care providers have incredibly important and demanding jobs. Physicians have enough on their hands without needing to worry about the intricacies of applying for payment to an insurance company. And as the number of patients covered by Medicare and Medicaid increases, the need to interact with the federal government adds to the burden of seeking payment for medical services. That’s why there’s a growing demand in hospitals, clinics, and treatment centers around the country for workers trained in medical billing and medical coding. These two activities streamline the interaction between the doctor and the agency responsible for payment, and greatly increase the ease and efficiency with which health care is provided in both medical clinics and hospitals.
