Anthem and a University of Pittsburgh Medical Center health plan in western Pennsylvania are the only two Medicare Advantage insurers offering the virtual visits, and the traditional Medicare program has tightly limited telemedicine payments to certain rural areas. And even there, the beneficiary must already be at a clinic, a rule that often defeats the goal of making care more convenient. Congress has maintained such restrictions out of concern that the service might increase Medicare expenses.
