Telemedicine introduces new medical and ethical questions. Historically, medical licensing applied only to the state of residence. This was practical and reasonable as medical workers lived and worked in one state thus could be licensed for that state. Telemedicine has the potential to remove all distance bars and to operate at any remote distance that can be accessed through Internet communication channels. In this case, multiple-state licensing and/or national licensing takes on an interesting and advisable characteristic. Many would be of the opinion that such expansive should be implemented.
