Telehealth is healthcare provided by any means other than a face-to-face visit. In telehealth services, medical and mental health information is used for diagnosis, consultation, treatment, therapy, follow-up, and education. Health information is exchanged interactively from one site to another through electronic communications. Telephone consultation, videoconferencing, transmission of still images, e-health technologies, patient portals, and remote patient monitoring are all considered telehealth services.
