An e-visit is a medical visit that happens entirely through text-based messaging on a secure online patient portal, with no live conversation required. Unlike a video call or phone appointment, an e-visit is asynchronous: you describe your symptoms in writing, and your provider reviews them later, then sends back a diagnosis and treatment plan. The whole exchange can happen over the course of hours or even days, without either person needing to be online at the same time.
How an E-Visit Differs From Telehealth
The term “telehealth” gets used loosely, but e-visits are a specific, narrower category. A telehealth visit typically means a live video or phone call with a provider in real time. A virtual check-in is a brief, provider-initiated exchange to decide if you need a full appointment. An e-visit is neither of those. It’s a patient-initiated, text-based clinical encounter through your provider’s online portal, and Medicare recognizes it as a distinct billable service separate from both telehealth and virtual check-ins.
The key distinction is that no one is on camera or on the phone. You type out your symptoms, answer questions, and attach photos if needed. Your provider reads everything, makes a clinical decision, and responds in writing with next steps, which might include a prescription, a recommendation for lab work, or advice to come in for an in-person exam.
What the Process Looks Like
You start an e-visit by logging into your healthcare system’s patient portal, the same one you’d use to check lab results or request a prescription refill. From there, you’ll typically fill out a structured questionnaire designed for your specific complaint. The system may ask you to describe your symptoms, note how long they’ve lasted, and list any medications you’re currently taking. Some portals limit you to a text box with a character count; others walk you through branching questions depending on your condition.
Once you submit, your provider reviews the information on their end. Response times vary by health system, but some integrated care settings tell patients to expect a reply within four hours, with actual turnaround often closer to 30 to 60 minutes. Your provider’s response will include a diagnosis if one can be made, a treatment plan, and any prescriptions sent directly to your pharmacy. If your symptoms suggest something that can’t be safely managed without an exam, they’ll let you know and help you schedule a follow-up.
Conditions Commonly Treated
E-visits work best for straightforward, low-acuity problems, the kind of thing you might otherwise call your doctor’s office about and handle over the phone. Early adopters built their e-visit systems around seven high-frequency conditions: sinus and cold symptoms, back pain, cough, diarrhea, pink eye, urinary symptoms, and vaginal irritation or discharge. Of those, sinus and cold complaints were the most popular, making up about 35% of e-visits in one of the first large patient cohorts studied.
Interestingly, the single largest category in that same cohort was “other,” at roughly 38% of all e-visits. Patients used the system for a wide range of issues that didn’t fit neatly into the predefined categories: blood pressure questions, skin conditions, diabetes management, sleep problems, pain, hemorrhoids, and more. This suggests that once people get comfortable with the format, they use it for a broader set of concerns than designers originally anticipated.
Who Can Use One
Under current Medicare rules, e-visits are only available to established patients, meaning you need an existing relationship with the provider or practice before you can initiate one. You can’t use an e-visit as your first point of contact with a new doctor. The visit also has to be initiated by you, not your provider, though your doctor’s office can let you know the option exists.
There are no geographic restrictions. Unlike some telehealth rules that were historically limited to rural areas or specific clinical settings, e-visits can be used by any established patient regardless of where they live. You just need access to your provider’s patient portal.
Cost and Insurance Coverage
Medicare Part B covers e-visits, and the billing is based on how much cumulative time your provider spends reviewing your case over a seven-day period. For physicians and nurse practitioners, there are three tiers: 5 to 10 minutes, 11 to 20 minutes, and 21 or more minutes. Other licensed clinicians like physical therapists, occupational therapists, speech-language pathologists, and clinical psychologists can also bill for e-visits under a separate set of codes.
If you have Medicare, the standard cost-sharing applies: after your Part B deductible, you pay 20% of the approved amount. For private insurance, coverage varies by plan. Many large health systems and insurers now cover e-visits, but the copay structure differs. Some charge a flat fee that’s lower than an office visit copay, while others treat it more like a standard outpatient encounter. It’s worth checking with your insurer before submitting one if cost is a concern.
Benefits and Limitations
The obvious advantage is convenience. You don’t need to take time off work, drive to a clinic, or sit in a waiting room. You can start an e-visit at midnight if that’s when you notice symptoms, and your provider will review it during working hours. For simple problems like a recurring urinary tract infection or a flare-up of a known condition, an e-visit can get you a prescription without disrupting your day.
E-visits also create a written record of the exchange by default, which can be useful for tracking symptoms over time or referencing what your provider recommended. And because the format is asynchronous, providers can take time to look up your chart, review your history, and respond thoughtfully rather than working within the constraints of a 15-minute appointment slot.
The limitations are real, though. Your provider can’t listen to your lungs, press on your abdomen, or look in your ear. Any condition that requires a physical exam, imaging, or urgent intervention isn’t appropriate for an e-visit. Chest pain, high fever, severe abdominal pain, or anything that feels like an emergency should go through traditional channels. The format also depends on your ability to describe symptoms clearly in writing, which can be a barrier for some people. If you struggle with the portal interface or find it hard to articulate what you’re feeling in text, an e-visit may not be the right fit.
