Telemedicine

Also known as: telehealth, virtual care, virtual visit, online doctor

Telemedicine (also called telehealth) allows patients to consult with healthcare providers through video calls, phone calls, or secure messaging instead of in-person visits.

It covers everything from a primary care video visit on your phone to remote specialist consultations, mental health therapy sessions, and chronic disease monitoring. The COVID-19 pandemic accelerated telemedicine adoption dramatically, and many regulatory barriers to reimbursement were relaxed, some permanently and others only temporarily.

Telemedicine, explained at three levels

At home

Telemedicine is seeing your doctor by video call instead of going to the clinic in person. You open an app or website, select a doctor or your regular provider, join a video call, describe your symptoms, and get a diagnosis and prescription if needed, all from home. It works well for common illnesses, prescription renewals, and follow-up appointments.

At work

Healthcare organizations offer telemedicine to extend access to patients who live far from clinics, have mobility limitations, or can't take time off work for in-person visits. From a business perspective, telemedicine reduces physical facility cost, increases provider capacity, and improves patient satisfaction scores, particularly for routine and follow-up care.

Real-world examples

At home

Aisha woke up with a severe ear infection on a Sunday. Instead of going to an urgent care clinic and waiting two hours, she opened her health insurance app, connected with a doctor via video in 10 minutes, received a diagnosis, and had a prescription sent to her pharmacy, where it was filled before noon.

At work

Fatima, a healthcare IT director, integrated her health system's Epic EHR with their Zoom for Healthcare telehealth platform. Patients received a visit link in their MyChart patient portal, clicked to join at appointment time, and the provider documented the visit directly in Epic during the call. Post-visit notes, orders, and prescriptions appeared in the patient's chart automatically.

Common confusions

  • Many assume telemedicine and telehealth mean the same thing — Telemedicine technically refers specifically to clinical care delivery at a distance: a doctor diagnosing and treating a patient remotely. Telehealth is the broader term that includes non-clinical services like health education, remote patient monitoring, administrative consultations, and wellness coaching. In practice, most people and many providers use the terms interchangeably.
  • Some believe a regular video call like Zoom or FaceTime is acceptable for telehealth — Standard consumer video apps don't meet HIPAA requirements for protected health information. Healthcare providers must use HIPAA-compliant platforms with Business Associate Agreements (BAAs) in place, such as Zoom for Healthcare, Doxy.me, or telehealth modules in major EHR systems. Using regular Zoom or FaceTime for clinical consultations exposes providers to significant HIPAA liability.
  • People think telemedicine works equally well for all medical conditions — Telemedicine is highly effective for routine care, prescription renewals, mental health, dermatology, and follow-ups. It's not appropriate for physical examinations requiring hands-on assessment, emergency conditions, complex diagnostics requiring in-person tests, or procedures. Knowing when to escalate a telehealth visit to in-person care is a core clinical competency in telehealth delivery.

For analysts

When a healthcare client is evaluating telehealth platforms, the EHR integration question is critical: a telehealth platform that doesn't integrate with their EHR will create parallel documentation workflows and increase provider burden. Native EHR telehealth modules (Epic's telehealth, Oracle Health's virtual visit) simplify this but may lag behind standalone platforms in user experience.

History & origin

Telemedicine has roots in the 1950s, when radiology images were transmitted over telephone lines between medical facilities. Space medicine programs in the 1960s advanced remote patient monitoring. Early videoconferencing-based telemedicine appeared in the 1990s but was limited by bandwidth and cost. Consumer-facing telehealth platforms (Teladoc, launched 2002; Doctor on Demand, 2013) began making telemedicine accessible to individuals. COVID-19 in 2020 produced a massive adoption spike: US telehealth visits increased 154% in the last week of March 2020 alone. Post-pandemic, telemedicine settled at a usage level significantly higher than pre-2020 and became a standard care delivery channel.
