Telemedicine is the use of technology that lets healthcare providers and people seeking medical services connect virtually. This gives you the freedom to receive treatment without having to go to an office for medical services. 

On the other hand, telehealth is a support tool — not a service. Telehealth is a way to improve patient care and physician education. It expands beyond telemedicine to cover nonclinical aspects of care. This includes appointment scheduling, continuing medical education, and physician training.
