Obviously being licensed nationally would end many impediments to telemedicine on a state-by-state basis. In 1996, a "Model Act" was created by the Federation of State Medical Boards to regulate telemedicine between state lines. A special license is required to practice medicine electronically but this license would still prohibit the actual practicing of medicine in person, unless that physician was licensed in each individual state.
States still have a great deal of say about the practicing of telemedicine. States are at liberty to determine how "regularly or frequently" a doctor engages in telemedicin and "[e]ach state medical board would define what "regular or frequent" means."
