Most people use "telemedicine" and "telehealth" as if they were two names for the same thing. They're not quite, and the gap between them traces back to a very specific moment in 1968, long before either word meant what it means today.
At Bask Health, we build the systems that power telemedicine and telehealth services for a wide range of healthcare brands, so the distinction isn't just trivia for us; it shapes how those services get built and described. Here's where the words actually came from, what separates them now, and why getting it right still matters.
A Word With a Stranger Origin Story Than You'd Expect
In the summer of 1967, a Massachusetts General Hospital physician named Kenneth Bird was moonlighting as the medical director at Boston's Logan Airport. The hospital was only a few miles away, but Boston traffic and a single tunnel turned the commute into an hour each way. Frustrated, Bird had an idea: put a camera at the airport and a camera at the hospital, and let him examine patients over a television link instead of driving. With funding from federal grants and help from a local public television station, that link went live in 1968, and according to MGH's own historical account, Bird is the physician credited with coining the word "telemedicine" to describe it.
"Telehealth" came later, and more gradually. As remote care technology expanded beyond direct clinical exams to include provider training, patient education, and public health coordination, the field needed a broader term than "telemedicine" could honestly encompass. By the time federal health agencies began writing formal definitions decades later, "telehealth" had become the umbrella term, with "telemedicine" narrowed to refer to something more specific beneath it.
So What's the Actual Difference Today?
The short version: telemedicine refers to clinical care delivered remotely, diagnosis, treatment, prescribing, and anything a patient would otherwise get in an exam room. Telehealth is the broader category, including telemedicine plus things that aren't direct clinical encounters at all: a nurse's continuing education webinar, a public health department's remote outreach program, a hospital's virtual administrative meeting between departments.
Here's the part that surprises people: even within the federal government, the definitions don't fully agree. The American Medical Association notes that CMS defines telehealth fairly narrowly as a real-time, two-way interaction between a patient and provider using audio and video equipment at a minimum. At the same time, HRSA's definition is much broader, explicitly including education and administration alongside clinical care. So when someone says a service "isn't real telehealth," it's worth asking which definition they're using, because there isn't just one.
Two Stories That Show the Difference Better Than a Definition
Definitions only go so far. These two scenarios show what the difference actually looks like in practice:
- Maria has a worsening rash. She opens an app, answers a few questions, and uploads a photo. A dermatologist reviews it, diagnoses contact dermatitis, and sends a prescription to her pharmacy that afternoon. This is telemedicine: a clinical diagnosis and treatment delivered remotely that could have occurred in an exam room instead.
- James is a nurse at a rural clinic. Once a month, he joins a video session hosted by specialists at a regional academic medical center, where they walk through complex cases and answer questions from clinics like his. No patient is being diagnosed in that session; it's professional education, delivered remotely. By HRSA's definition, this is telehealth. It is not telemedicine, because no clinical care is being delivered to a patient.
Both James and Maria would probably describe what they did as "using telehealth." Maria's experience is also in telemedicine.

Why the Distinction Still Trips People Up
Plenty of companies use "telehealth" in their branding while delivering services that are entirely telemedicine, and vice versa; there's no rule requiring the name to match the technical definition. That's mostly harmless for marketing, but it becomes a real issue the moment the wrong word ends up in a contract, an insurance claim, or a state regulation that's written around one term specifically. A service description that says "telehealth consultation" when a payer's policy is written around "telemedicine visits" (or the reverse) can create avoidable friction during billing or compliance review, not because the care was wrong, but because the language didn't match the rule.
How Bask Health Thinks About the Difference
Bask Health was built primarily around the telemedicine side of this distinction, the clinical workflow that takes a patient from intake to diagnosis to treatment. Our questionnaire and patient portal builder capture the clinical information a provider needs, our EMR and e-prescribing tools connect that information to a documented diagnosis and a prescription, and our pharmacy fulfillment network gets the treatment to the patient, the same chain of events in Maria's story above.
At the same time, the platform supports broader telehealth use cases that healthcare brands build on top of that clinical core: patient education content, ongoing portal communication, and the ongoing touchpoints that fall outside a single billable visit but still matter to how a virtual clinic runs day-to-day.
Conclusion
Telemedicine and telehealth aren't interchangeable; one is a clinical activity, the other is the broader category it sits inside, and the line between them traces back to a frustrated doctor's commute in 1968, long before anyone wrote it into policy. Knowing which one actually describes a given service helps avoid the kind of mismatched language that causes real friction in billing, contracts, and compliance, even if it makes no difference at all to the patient receiving care.
