You probably know the feeling. You don’t think it’s an emergency, but you do feel sick enough to see a doctor. Still, getting there can be a problem if you don’t drive, don’t feel well enough to or are reluctant to venture out on an icy road—and just the thought of getting dressed requires more energy than you can muster. Then there’s the wait. Sitting for even a half-hour in a doctor’s office or urgent care waiting room filled with sneezing, coughing, germ-laden patients is not an option. Top that with getting sick on a weekend or holiday when even getting a call-back from your doctor is a small miracle.

Wouldn’t it be wonderful, you think, as you crawl back into bed, if doctors still made house calls?

They do—virtually, via a secure online connection to your smartphone, tablet or computer. And there may be only a 10-minute or less wait time to “see” the doctor. That is especially appealing given that the average wait time in a major city for a non-urgent problem like a bout of poison ivy is five days to two months.

Telehealth or telemedicine as it’s also called—video calling with doctors, email and text messaging, even Facebook messaging—is becoming the next big thing. In fact, one telehealth company, Teladoc, already has 15 million members.

Your Virtual House Call: How It Works

Telehealth is not meant to replace your personal physician, but rather offers a convenient, 24/7 consultation about a non-emergency health problem with a doctor who is licensed to practice in your state.

Signing up for most telehealth services is as simple as going online, filling out contact information and, if you want to have your doc visit via your mobile device, downloading an app. You can set up an appointment or have a video appointment with a healthcare professional right away. Some services also will communicate with you via email or phone.

Once you’ve scheduled a visit, depending on your issue (for example, if you’re “seeing” a dermatologist), you might be asked to take pictures of yourself and upload them to the website or app. If you use a smartphone or tablet, it’s an easy two-step process.

Why You Might Use Telehealth

You would use a virtual health service for a non-emergency situation, such as a sore throat, cold or flu, diarrhea, sports injury, a distressing rash or other skin issue, symptoms of a sinus or urinary tract infection—even a mental health issue. The online doctor evaluates your condition and gives you medical advice and instructions for self-care. The doctor can also recommend over-the-counter medication or email a prescription to your local pharmacy; some will make a specialist referral.

In the not distant future, Medicare may cover telehealth services for people with certain chronic conditions that need regular follow-up.

In addition to primary care for minor health complaints, several telehealth services now include behavioral health counselors, including psychiatrists, for treating people with symptoms of depression and anxiety. Some also offer consultations with a specialist, nutritional counseling for those with diabetes or other chronic illnesses, and orders for diagnostic testing.

Depending on the service, you might be able to choose a doctor on the company’s roster. Others assign you to a physician, specialist or counselor depending on your needs. All healthcare professionals you’ll see are board certified and state-licensed.

Who Pays?

The cost of a visit typically runs from $35 to $50, possibly more, depending on consultation time. Some services also charge a monthly subscription fee.

Some insurance company plans—for example, United Health Care, Cigna and Aetna, including some ACA marketplace plans—may cover the cost. More and more companies are including telehealth services in their benefit plans.

Some 49 state Medicaid programs will reimburse for telehealth video visits.

How about Medicare? Original Medicare only covers telehealth for seniors living in remote rural areas, but some Medicare Advantage plans—as many as 72 according to this source, most notably Anthem and Humana plans—cover telehealth for seniors in some cases. And Medicare is the next major area for growth, Modern Healthcare reports. Already, Medicare pilot programs are underway in some states, among them programs that are evaluating telehealth for chronic conditions common to seniors.

If you have a Medicare supplemental plan, ask about coverage and deductibles for telehealth visits. You insurer may be partnered with a virtual health care service or cover the cost of a visit.

Here’s a sampling of telehealth services currently available. All allow you to see the doctor via a computer or mobile app.
