Short answer

Telehealth is the delivery of healthcare services remotely through phone, secure messaging, or video instead of an in-person visit. It is generally best suited to non-emergency needs a clinician can evaluate through conversation and history, such as common minor illnesses, medication follow-ups, and ongoing care check-ins, and it does not replace a physical exam or emergency care.

What telehealth actually is

Telehealth is a delivery method, not a single service. It describes any healthcare interaction that happens remotely rather than in an exam room: a video call with a clinician, a secure message thread reviewed by a provider, or a phone consultation. The clinical standards that apply are generally the same ones that apply in person — a licensed clinician still has to decide whether what you need can be handled safely without physically examining you.

Because the term is so broad, two services both labeled 'telehealth' can look completely different in practice: one might be a single paid consultation focused on a specific medication question, while another might be an ongoing membership designed to function like a virtual primary care relationship.

The main service types

Most consumer telehealth options fall into a small number of categories, and figuring out which one matches your need is usually more useful than comparing individual brands.

  • Prescription-related care: a focused consultation where a clinician reviews whether a specific prescription is appropriate.
  • Virtual urgent care: a same-day visit for a new, non-emergency problem such as a minor illness or injury.
  • Ongoing care and health plans: a membership or subscription structure meant for continuing access rather than a single visit.
  • Employer and business telehealth: access arranged by an organization for employees or members, usually through a group agreement.

How a typical visit works

Regardless of service type, most telehealth visits follow a similar shape: you register with a provider, complete an intake describing your situation and history, and a licensed clinician reviews that information before the visit itself. Depending on the provider and the issue, the visit may be a written review, a phone call, or a live video appointment.

After the visit, the clinician documents the encounter, may send a prescription to a pharmacy if appropriate, and may recommend follow-up or in-person care if the issue turns out to need it. See our step-by-step breakdown for more detail on each stage.

What telehealth costs, conceptually

Telehealth pricing is not standardized. A single consultation may be billed as a flat fee, a membership may charge monthly regardless of visits, and insured visits may be billed through your normal copay structure. The only reliable way to know the real cost is to check directly with the specific provider and, if you plan to use insurance, with your insurer.

We do not publish a price on any page unless we have verified it directly with the provider named. If a page does not list a price, it means we have not yet confirmed one.

What telehealth cannot do

Telehealth cannot perform a physical examination, take vital signs directly, run in-office lab tests, or handle any condition where hands-on assessment is necessary for safety. It is not appropriate for emergencies of any kind. A responsible provider will tell you when your situation needs in-person or emergency care rather than trying to manage it remotely.

How to research a telehealth provider before you pay

  • Confirm the provider is licensed to operate, and that its clinicians are licensed, in your state.
  • Check whether the service is a single visit or an ongoing subscription, and read the cancellation terms.
  • Ask what happens, and what you pay, if the clinician determines they cannot help with your issue.
  • Verify which pharmacies the provider can send prescriptions to, if relevant.
  • Look for a clear description of how your health information is stored and used.

Limitations to keep in mind

  • This page is educational and does not evaluate or recommend a specific medical course of action for you.
  • We do not employ clinicians, run consultations, or make treatment or prescription decisions.
  • Availability, pricing, and clinical scope differ by provider and by state, and change over time.

Questions worth asking before you pay

  • Is this service licensed to operate in my state?
  • Is this a one-time visit or an ongoing subscription?
  • What happens if the clinician says I need in-person care instead?
  • How and where will any prescription be sent?
  • What does this cost in total, including any recurring fees?

Frequently asked questions

What is telehealth, in plain terms?

Telehealth is healthcare delivered remotely, usually by phone, secure message, or video, instead of an in-person office visit. It covers everything from a five-minute prescription consultation to an ongoing virtual primary-care relationship.

Is telehealth as good as seeing a doctor in person?

It depends on what you need. Telehealth works well for problems a clinician can assess through conversation and history, but it cannot replace a physical exam, imaging, or lab work performed on site.

How much does a telehealth visit cost?

Pricing varies widely by provider, service type, and whether insurance is involved. We do not publish a price on this site unless we have verified it directly with a provider.

Is telehealth covered by insurance?

Many insurers cover at least some telehealth services, but coverage rules vary by plan, state, and provider network. Confirm directly with your insurer and the provider before your visit.

Does Telehealth Discover provide the care itself?

No. We are an independent research and comparison site. We do not employ clinicians, run visits, or store health information. Every visit happens on an independent provider's own platform.
