A list of the medical industry's current coding procedures is published by the American Medical Association. The United States National Library of Medicine also has standards and codes specific to various professions, such as dentistry. The codes are used to describe specifics of medical treatments and services, including the use of different specialties and any technology that was needed, such as an MRI.
Medical codes are used by Medicaid and insurance providers to classify the services rendered by a hospital into billable sections. The codes are frequently updated to reflect new findings in medicine, such as a new disease or treatment. There are international codes used universally, and the Centers for Disease Control and the World Health Organization are responsible for keeping these codes current.
