The Medicare & You handbook provided the following description of "telehealth":

"Medicare covers services like office visits, psychotherapy, consultations, and certain other medical or health services provided by an eligible provider who isn’t at your location using an interactive, two-way telecommunications system (like real-time audio and video). These services are available in rural areas, under certain conditions, but only if you’re located at: a doctor’s office, hospital, critical access hospital, Rural Health Clinic, Federally Qualified Health Center, hospital-based dialysis facility, skilled nursing facility, or community mental health center.

Medicare has expanded telehealth to include:

• You can get certain telehealth services at renal dialysis facilities and at home.
• You can get telehealth services for faster diagnosis, evaluation, or treatment of symptoms of an acute stroke no matter where you’re located.
• If you have a substance use disorder [such as alchoholism] or a co-occurring mental health disorder, you can get telehealth services from home.

For most of these services, you’ll pay the same amount that you would if you got the services in person."

The Medicare & You handbook continues on to expand the geographically-limited concept telehealth noting that:

"Starting in 2020, Medicare Advantage Plans may offer more telehealth benefits than Original Medicare. These benefits will be available no matter where you’re located, and you can use them at home instead of going to a health care facility. Check with your plan to see what additional telehealth benefits are offered."
