What Telehealth Is Actually Good For — and What It Isn't

Telehealth is very good at some things, useless at others, and marketed as though the difference did not exist. Knowing where the line falls protects you, and it also makes the operations that blur it deliberately much easier to spot.

What remote care genuinely does as well

Start with the uncomfortable fact that makes telehealth work: the great majority of diagnostic information in an ordinary consultation comes from what you say, not from what the clinician touches. A careful history is the single most productive part of most appointments. It transfers to a video call intact, and sometimes improves, because a clinician who cannot examine you tends to listen harder and ask more.

Medication management. Reviewing what you take, why, at what dose, what has and has not worked, what side effects you are having, and whether anything needs adjusting. This is conversation and record review. It works remotely.

Follow-up. Checking whether a treatment started six weeks ago is doing what it should. Most follow-up appointments in most specialities are a conversation plus a look at some numbers. Requiring a patient to take half a day off work and drive across a city for that is a habit, not a clinical necessity.

Mental health care. This is the strongest evidence base in telehealth. Psychotherapy and psychiatric medication management delivered by video have been compared with in-person care repeatedly and generally hold up well. Some patients disclose more from their own living room than they do in a clinic, and access improves substantially for people who cannot easily travel.

Chronic condition monitoring. Blood pressure, blood glucose, weight, symptom diaries. Home devices produce more data points over time than an occasional clinic reading does, and a single blood pressure taken after you rushed to an appointment was never a great measurement anyway.

Results, explanation and decisions. Going through lab results, explaining what a diagnosis means, weighing up options. Nobody needs to be in the room for that.

Reaching people who could not otherwise reach a clinician. In parts of northern Michigan the nearest relevant specialist is a long drive on winter roads. Telehealth does not create providers where there are none, but it changes who can reach the ones that exist, as we cover in telehealth in rural Michigan.

What it cannot do

Any service that will not tell you this is not being straight with you.

Physical examination. Nobody can listen to your chest, palpate your abdomen, look in your ear, check a reflex, feel a lymph node, assess a joint properly or perform any internal examination through a screen. Some of that can be partly compensated for. A patient can be talked through pressing their own abdomen and reporting what hurts. Most of it cannot.

Anything acute. Chest pain, difficulty breathing, sudden severe headache, signs of stroke, severe abdominal pain, a significant head injury, uncontrolled bleeding, an allergic reaction in progress. Telehealth is the wrong tool and using it costs time you may not have. Call 911 or go to an emergency department.

Anything needing imaging, on-site samples or a procedure. X-rays, ultrasound, CT, MRI, most blood draws, biopsies, wound closure, injections, removals. A remote clinician can order tests and interpret results, but somebody has to be physically present to take the sample or make the image.

Skin, sometimes. Some skin complaints are perfectly assessable from a good photograph. Others need to be seen under proper light, felt, measured, or examined with a dermatoscope. A remote clinician who cannot be certain about a lesion should tell you to be seen in person, and telling you that is good practice rather than a failure.

Anywhere the exam is the diagnosis. A new murmur, a suspicious mass, an unexplained neurological sign. If the examination is what settles the question, the appointment needs to be in a room.

How to identify a prescription mill

The distinction is not between telehealth and in-person care. Prescription mills have operated out of physical buildings for decades. The distinction is between practices that make a clinical decision and operations that process an order and dress it as one.

The fee depends on the outcome

This is the clearest signal there is. "No approval, no charge." "Money-back guarantee if you don't qualify." It sounds consumer-friendly and it is structurally corrupt: the person deciding whether you meet the criteria gets paid only if the answer is yes. A legitimate practice charges for the clinician's time and judgement, and you pay the same whether the answer helps you or not.

Approval is promised before anyone has spoken to you

"Guaranteed approval." "Approved in minutes or your money back." "99% approval rate." Nobody can promise you a prescription, a certification or any other clinical outcome before evaluating you, because the evaluation is what determines the outcome. A promise made in advance is a statement that the evaluation is decorative.

No medical history is taken

A two-minute quiz with six checkboxes is not a history. A real evaluation asks about your conditions, your surgeries, your family history, every medication and supplement you take, allergies, alcohol and substance use, pregnancy status where relevant, and what you have already tried. If nobody asked, nobody assessed.

You never learn who treated you

If the site never names the prescribing clinician, if there is no way to check their licence, and if "our medical team" is as specific as it gets, that opacity is a choice.

The product is decided before the visit

If you can select the medication first and the consultation exists to authorise it, the sequence of medicine has been inverted. Assessment precedes treatment.

There is no follow-up and no way to reach anyone

Prescribing a drug that needs monitoring, then having no monitoring, no accessible clinician and no plan, is not treatment. We list the full set of warning signs in how to spot a prescription mill.

Informed consent, and what it should contain

Consent to telehealth is a specific thing, not a checkbox on a payment page. A proper consent document, which you should be able to read before you agree to it and keep afterwards, should tell you at minimum:

• What telehealth is and how your visit will be conducted.
• Its limitations, explicitly including that a physical examination is not possible and that in-person evaluation may still be necessary.
• What alternatives exist, including being seen in person.
• Who will have access to your information, how it is stored, and the privacy and security risks involved in electronic transmission.
• What happens if the technology fails partway through a consultation.
• What to do in an emergency, with the explicit statement that the service is not for emergencies.
• The full fee, what it covers, and what it does not.
• That you may withdraw consent at any time.

Consent that consists of one line agreeing to terms of service is not informed consent. Read it. If a service will not show it to you until after you have paid, that itself is the answer.

Your right to know who is treating you

You are entitled to know the name of the clinician treating you, their professional credential, whether they are a physician, nurse practitioner or physician assistant, and the states in which they hold a licence. You are entitled to verify that licence, which you can do free through the relevant state board's public lookup.

Asking is normal. A practice that finds the question awkward has told you something. This and the rest of what you are owed as a patient is covered in your rights as a telehealth patient.

State licensure: the rule that surprises people

Medical licensure is issued by states, and the general rule is that the clinician must be licensed in the state where you are physically located at the time of the consultation. Not where the clinic is incorporated. Not where the clinician lives.

The practical consequences are worth understanding. If you live in Michigan and travel to Illinois, a visit that happens while you are in Illinois may need an Illinois-licensed clinician. If you are a student registered at your parents' address but living in another state, the state you are actually in is what matters. And a national telehealth brand does not have one licence covering the country; it maintains clinicians licensed state by state, or none.

There are mechanisms that ease this. An interstate compact expedites obtaining licences in multiple states, some states have specific telehealth registration routes, and there are narrow exceptions for consultations and for follow-up with an existing patient. None of them abolishes the underlying rule.

Controlled substances add a further federal layer. Prescribing controlled substances by telemedicine is governed by federal rules that have been extended, revised and re-proposed repeatedly in recent years, and their status remains unsettled. Licensure and controlled-substance rules change; verify anything you plan to rely on with the relevant state medical board and, for controlled substances, with the DEA.

This is also why our state-specific services are exactly that. Certification services for Michigan, Illinois and California are separate because the licensure, the programme rules and the regulators are separate. Michigan is administered by the Cannabis Regulatory Agency, Illinois by IDPH, and California involves county health departments alongside the state's Department of Cannabis Control. None of those rules travel across a state line.

Your records

Federal privacy law gives you a right of access to your own medical records held by a covered provider. You can request a copy, you can generally receive it in the electronic format you ask for if it can be readily produced, and the provider must respond within a defined period. A reasonable, cost-based fee may be charged for copying; a fee designed to discourage you is not permitted. You also have a right to request corrections to information you believe is wrong.

Ask a prospective telehealth practice how you obtain your records, in what format, and how long it takes. A practice that has not thought about it is a practice that may not be keeping much of a record. That matters later, when another clinician needs to know what you were prescribed and why.

Privacy, and what health websites actually do

This part gets less attention than it deserves.

Privacy law protects the information your provider holds about you. It says much less about what happens on the website before you become a patient. Many health websites load third-party analytics and advertising code, and that code can transmit the page you visited, together with identifiers, to companies that had nothing to do with your care.

The page address alone can be revealing. A URL containing a condition name discloses something about you before you have typed a word or given a name. Regulators have taken this seriously: federal agencies have issued guidance on tracking technologies in the health context and have brought enforcement actions against health companies for sharing user data with advertising platforms. Parts of that guidance have been contested in court, so the legal position is still developing, but the underlying practice is real and widespread.

What you can reasonably do: read the privacy policy and look specifically for whether data is shared with advertising partners; use your browser's tracker blocking and private browsing for sensitive searches; and ask a practice whether it has business associate agreements in place with the vendors that touch patient data. We go into detail, including how to check what a site is loading, in what health websites do with your data.

Using it well

Telehealth is a tool with a defined scope. Used inside that scope it is efficient, evidence-supported and often better than the alternative of not being seen at all. Used outside it, or used by an operation designed to sell rather than assess, it is worse than useless.

The practices worth using look much the same as good practices anywhere. They take a history. They tell you what they cannot do. They put their clinicians' names and licences in front of you. They charge for time, not for outcomes. They keep records you can get hold of. They refer you elsewhere when that is the right answer, and they occasionally tell you no.

If cost is a consideration, note that some telehealth expenses are eligible for tax-advantaged health accounts and some are not, and the boundary is not where most people guess; using HSA and FSA funds for telehealth sets out the general rules. And when you want to talk to a clinician about your own situation rather than read about the category, you can book a consultation.
