In the last decade, rapid advances in medicine and technology has resulted in the use of new terms. Policymakers, healthcare systems, advocacy groups, and vendors may unknowingly use terms incorrectly when discussing medicine and technology. This is especially true when it comes to the terms, telemedicine and telehealth. Although the words are often used interchangeably, there is certainly a difference between the two.

It has been around for decades, but in recent years private insurers, employers, and government programs have expanded their coverage. By 2016 at least half of U.S. healthcare institutions and hospitals were using some form of telehealth. And last September the Senate passed a bill that will expand Medicare coverage for telehealth services, if it’s signed into law.
