Telehealth is real medicine: what a virtual doctor can and cannot do

There are still misconceptions about telemedicine. Here is what a board-certified physician can genuinely accomplish remotely, and where in-person care is still needed.

Telehealth is real medicine: what a virtual doctor can and cannot do

The misconception: “you cannot really diagnose anything virtually”

This is one of the most common things new patients say, and it is worth addressing directly. A medical diagnosis is based primarily on history and symptoms. Studies show that in primary care, 70 to 80% of diagnoses are made from the patient’s history alone, before any physical exam or test is ordered.

When your physician asks when your symptoms started, what they feel like, what makes them better or worse, what medications you take and what other conditions you have — that is exactly what would happen in an office. The absence of a stethoscope does not change that diagnostic process for most common conditions.

What can be done virtually

·Diagnose and treat infections — UTIs, sinus infections, skin infections, pink eye
·Evaluate and treat respiratory illness — flu, COVID, allergies
·Prescribe non-controlled medications, and refill medications you already take
·Order lab work and interpret the results
·Provide medical weight management, including GLP-1 prescribing
·Evaluate skin conditions — rashes, acne, eczema — which you can show directly on camera
·Provide sick notes and documentation
One honest limit

Li Health is a focused practice, not a primary care clinic. We do not manage chronic conditions like high blood pressure, diabetes or thyroid disease on an ongoing basis — though we can refill a medication you already take, or bridge you when you are temporarily without access to your regular physician. Keep a primary care physician for long-term management.

When you will be told to go in person

Patient safety comes before a booking. Your physician will always be honest if a virtual visit is not the right setting. You need in-person evaluation for:

In person, without delay
Chest pain, shortness of breath, or signs of a heart attack
Stroke symptoms — face drooping, arm weakness, slurred speech
Severe abdominal pain
High fever with a stiff neck
Injuries needing imaging, sutures or a physical exam
Anything needing an in-office procedure

“We would rather earn your trust by being honest about the limits than overpromise what a virtual visit can do.”

Not sure if a virtual visit can help?

Start a $39 quick care visit and describe your situation. If it turns out to be beyond the scope of virtual care, you will be told immediately — and you choose whether to be refunded in full or move to a video visit.
